SDK Functions and Usage

  1. MobileRTC Initialize

To integrate with MobileRTC, MobileRTC should be initialized in your app.

didFinishLaunchingWithOptions: in AppDelegate class, code snippets as following:

1. Set MobileRTC Domain
[[MobileRTC sharedRTC] setMobileRTCDomain:@“”];
2. Set MobileRTC Resource Bundle path
//Note: This step is optional, If MobileRTCResources.bundle is included in other bundle/framework, use this method to set the path of MobileRTCResources.bundle, or just ignore this step
NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
[[MobileRTC sharedRTC] setMobileRTCResPath:bundlePath];
3. Set MobileRTC Root Navigation Controller
//Note: This step is optional, If app’s rootViewController is not a UINavigationController, just ignore this step.
[[MobileRTC sharedRTC] setMobileRTCRootController:navController];
4. MobileRTC Authenticate
MobileRTCAuthService *authService = [[MobileRTC sharedRTC] getAuthService];
if (authService){
authService.delegate = self;
authService.clientKey = @“xx-xx-xxx”;
authService.clientSecret = @“yy-yy-yyy”;
[authService sdkAuth];

Once your app logs in with work email, MobileRTC will auto login while app is launched each time, and your app can stop it by calling interface “logoutRTC”.

5. Login with work email account
MobileRTCAuthService *authService = [[MobileRTC sharedRTC] getAuthService];
if (authService){
BOOL ret = [authService loginWithEmail:@"xx@xx.xx" password:@"yyy"];
6. Logout
MobileRTC AuthService *authService = [[MobileRTC sharedRTC] getAuthService];
if (authService){
[authService logoutRTC];


2. Listener for MobileRTCAuthDelegate

To check the authentication from MobileRTC, the listener can be added in AppDelegate.

#pragma mark - Auth Delegate 
//Sink auth event 
- (void)onMobileRTCAuthReturn:( MobileRTCAuthError)returnValue { 
NSLog(@"onMobileRTCAuthReturn %d", returnValue); } 
//Sink login event 
- (void)onMobileRTCLoginReturn:(NSInteger)returnValue { 
NSLog(@"onMobileRTCLoginReturn result=%zd", returnValue); 
//Register delegate of pre-meeting service after login with work email account 
MobileRTCPremeetingService *service = [[MobileRTC sharedRTC] getPreMeetingService]; if (service) {service.delegate = self;} }
//Sink logout event
- (void)onMobileRTCLogoutReturn:(NSInteger)returnValue
NSLog(@"onMobileRTCLogoutReturn result=%zd", returnValue);

  1. Start Meeting

After the stack is initialized, your app can start a meeting.

MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if (ms){
ms.delegate = self;
//For API User
NSDictionary *paramDict = @{
                            kMeetingParam_UserType:@( MobileRTCUserType_ZoomUser), 
//For login user start scheduled meeting
 NSDictionary *paramDict = @{kMeetingParam_MeetingNumber:kSDKMeetNumber,kMeetingParam_IsAppShare:@(appShare)};
//For login user start instant meeting
NSDictionary *paramDict = @{kMeetingParam_IsAppShare:@(appShare)};
MobileRTCMeetError ret = [ms startMeetingWithDictionary:paramDict]; NSLog(@"onMeetNow ret:%d", ret);

  1. Join Meeting

MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if (ms){
ms.delegate = self;
//For Join a meeting with password
NSDictionary *paramDict = @{ 
//For Join a meeting
NSDictionary *paramDict = @{
MobileRTCMeetError ret = [ms joinMeetingWithDictionary:paramDict]; NSLog(@"onJoinaMeeting ret:%d", ret);


  1. Listener for Meeting Service

Once App has started/joined a meeting, the stack will return the meeting state by Meeting Service Delegate.

#pragma mark - Meeting Service Delegate

- (void)onMeetingReturn:( MobileRTCMeetError)error internalError:(NSInteger)internalError
{NSLog(@"onMeetingReturn:%d, internalError:%zd", error, internalError);}
- (void)onMeetingStateChange:( MobileRTCMeetingState)state
{NSLog(@"onMeetingStateChange:%d", state);}


  1. Get/Set Meeting Audio/Video State

After the stack is initialized, your app can change the meeting audio/video state.

MobileRTCMeetingSettings *settings = [[MobileRTC sharedRTC] getMeetingSettings];
if (!settings)
return nil;
BOOL isAutoConnected = [settings autoConnectInternetAudio]; 
BOOL isAudioMuted = [settings muteAudioWhenJoinMeeting]; 
BOOL isVideoMuted = [settings muteVideoWhenJoinMeeting]; 
BOOL disabled = [settings driveModeDisabled];
BOOL disabledCallIn = [settings callInDisabled]; 
BOOL disabledCallOut = [settings callOutDisabled];

//Set Meeting Audio/Video State
UISwitch *sv = (UISwitch*)sender;
[[[MobileRTC sharedRTC] getMeetingSettings] setAutoConnectInternetAudio:sv.on];
[[[MobileRTC sharedRTC] getMeetingSettings] setMuteAudioWhenJoinMeeting:sv.on]; 
[[[MobileRTC sharedRTC] getMeetingSettings] setMuteVideoWhenJoinMeeting:sv.on];
[[[MobileRTC sharedRTC] getMeetingSettings] disableDriveMode:sv.on];
[[[MobileRTC sharedRTC] getMeetingSettings] disableCallIn:sv.on]; 
[[[MobileRTC sharedRTC] getMeetingSettings] disableCallOut:sv.on];


  1. Pause/Resume Meeting Audio

Once in the meeting, your app can pause/resume the meeting audio.

BOOL isNoAudio = [[[MobileRTC sharedRTC] getMeetingService] isNoMeetingAudio];
[[[MobileRTC sharedRTC] getMeetingService] pauseMeetingAudio:!isNoAudio];
  1. Option to Show/Hide Thumbnail video and Hide “Leave Meeting” item in Host side

Your app can show/hide thumbnail video while viewing/starting share in meeting.

[[[MobileRTC sharedRTC] getMeetingSettings] setThumbnailHidden:hidden];

Partner can hide “Leave Meeting” item in host side in meeting, code snippets as following:

[[[MobileRTC sharedRTC] getMeetingSettings] setHostLeaveHidden:hidden];


  1. Customize the participant invite template
//To enable to customize Invite Participant, you should implement the delegate method “- (void)onClickedInviteButton:(UIViewController*)parentVC”, Partner can present customized Invite view controller in this method.

- (void)onClickedInviteButton:(UIViewController*)parentVC
InviteViewController *inviteVC = [[InviteViewController alloc] init]; 
UINavigationController *nav = [[UINavigationController alloc]
nav.modalPresentationStyle = UIModalPresentationFormSheet;
[parentVC presentViewController:nav animated:YES completion:NULL];

And partner can get meeting ID and join meeting URL by the following properties:

NSString *meetingID = [MobileRTCInviteHelper sharedInstance].meetingID; 
NSString *meetingURL = [MobileRTCInviteHelper sharedInstance].joinMeetingURL;


10.Customize the content of “Invite by Message”, “Copy URL” and “Invite by Email”

Your app can customize the content of “Invite by Message (SMS)”, “Copy URL” and “Invite by Email” after the meeting has started, and can enable/disable the feature of “Invite by Message”/ “Copy URL”/“Invite by Email”.

//For Enable/Disable Copy URL
[MobileRTCInviteHelper sharedInstance].disableCopyURL = YES;
//For Enable/Disable Invite by Email
[MobileRTCInviteHelper sharedInstance].disableInviteEmail = YES;
//For Enable/Disable Invite by Message
[MobileRTCInviteHelper sharedInstance].disableInviteSMS = YES;
if (state == MobileRTCMeetingState_InMeeting)
//For customizing the content of Invite by SMS
NSString *meetingID = [[MobileRTCInviteHelper sharedInstance] meetingID];
NSString *smsMessage = [NSString stringWithFormat:NSLocalizedString(@"Please join meeting with ID: %@", @""), meetingID];
[[MobileRTCInviteHelper sharedInstance] setInviteSMS:smsMessage];
//For customizing the content of Copy URL
NSString *joinURL = [[MobileRTCInviteHelper sharedInstance] joinMeetingURL]; 
NSString *copyURLMsg = [NSString stringWithFormat:NSLocalizedString(@"MeetingURL: %@", @""), joinURL];
[[MobileRTCInviteHelper sharedInstance] setInviteCopyURL:copyURLMsg];
//For customizing "Invite by Email"
[MobileRTCInviteHelper sharedInstance].inviteEmailSubject = @"Invite by Email";
[MobileRTCInviteHelper sharedInstance].inviteEmailContent = [NSString
stringWithFormat:NSLocalizedString(@"Please join meeting with ID: %@", @""), meetingID];

11.Turn on/off cloud recording

MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
//To check whether support cloud record or not
[ms isCMREnabled];
//To check whether cloud record is in progress
[ms isCMRInProgress];
//Turn on cloud record
[ms turnOnCMR:YES];
//Turn off cloud record
[ms turnOnCMR:NO];

12.Customize to Dial-Out

 You can customize the behavior of Dial-Out if the account supports dial-out.

//To enable to customize Dial-Out, Partner should implement the delegate method “- (void)onClickedDialOut:(UIViewController*)parentVC isCallMe:(BOOL)me”, Partner can start dial-out in this method.
- (void)onClickedDialOut:(UIViewController*)parentVC isCallMe:(BOOL)me
MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if (!ms)
if ([ms isDialOutInProgress]){
NSLog(@"There already exists an ongoing call");
NSString *callName = me ? nil : @"Dialer";
BOOL ret = [ms dialOut:@"+866004" isCallMe:me withName:callName]; 
NSLog(@"Dial out result: %zd", ret);
And partner can get dial-out status by the following code:
- (void)onDialOutStatusChanged:(DialOutStatus)status
NSLog(@"onDialOutStatusChanged: %zd", status);


13.Customize call out to  H.323/SIP Room System (if its enabled in your account)

//After joined meeting, Partner can call Room System directly as following
//For Call-In Room Device
ms sendPairingCode:@"xxxyyy"];
//For Call-Out Room Device
MobileRTCRoomDevice *device = [[MobileRTCRoomDevice alloc] init];
device.deviceName = @"abc"; 
device.ipAddress = @""; device.e164num = 0;
device.deviceType = MobileRTCDeviceType_H323; 
device.encryptType = MobileRTCDeviceEncryptType_None;
[ms callRoomDevice:device];

//And partner can get Call Room System status by the following code:
- (void)onSendPairingCodeStateChanged:(NSUInteger)state
NSLog(@"onSendPairingCodeStateChanged %zd", state);
- (void)onCallRoomDeviceStateChanged:(NSUInteger)state
NSLog(@"onCallRoomDeviceStateChanged %zd", state);


14.Provide Participants list in meeting

If your app want to implement a participant list, the stack provides interface to get attendees in meeting, and provides delegate to notify your app if attendees’ state gets updated.

MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService]; NSArray *users = [ms getInMeetingUserList];
NSLog(@"In Meeting users:%zd", users.count);
MobileRTCMeetingUserInfo *myself = [ms getMyUserInfo]; 
NSLog(@"In Meeting myself:%@", myself);
And provides delegate to notify Partner if attendees’ state updated by the following code:
- (void)inMeetingUserUpdated


15. Notify app if it become active/inactive

MobileRTC should notify the common layer that app will become inactive in applicationWillResignActive: in AppDelegate class.

[[MobileRTC sharedRTC] appWillResignActive];

MobileRTC should notify the common layer that app did enter backgroud in applicationDidEnterBackground: in AppDelegate class,.

[[MobileRTC sharedRTC] appDidEnterBackgroud];

MobileRTC should notify the common layer that app did become active in applicationDidBecomeActive: in AppDelegate class.

[[MobileRTC sharedRTC] appDidBecomeActive];

16.Pre-Meeting Service

This class provides support for schedule/edit/delete meeting once login with work email.

//For Schedule Meeting
MobileRTCPremeetingService *service = [[MobileRTC sharedRTC] getPreMeetingService];
if (service)
id<MobileRTCMeetingItem> item = [service createMeetingItem]; 
[item setMeetingTopic:@"xxx"];
[item setStartTime:[NSDate date]];
[item setTimeZoneID:[NSTimeZone defaultTimeZone].name];
[item setDurationInMinutes:60];
[service scheduleMeeting:item];
[service destroyMeetingItem:item];

//For Edit Meeting
MobileRTCPremeetingService *service = [[MobileRTC sharedRTC] getPreMeetingService];
if (service)
id<MobileRTCMeetingItem> item = [service getMeetingItemByNumber:123456789];
if (item){
[item setMeetingTopic:@"xxx yyy"]; 
[item setMeetingNumber:123456789]; 
[item setStartTime:[NSDate date]]; 
[item setMeetingPassword:@"yyy"];
[service editMeeting:item];}

//For Delete Meeting
MobileRTCPremeetingService *service = [[MobileRTC sharedRTC] getPreMeetingService];
if (service){
id<MobileRTCMeetingItem> item = [service getMeetingItemByNumber:123456789];
if (item){
[service deleteMeeting:item];}

//For List Meeting
MobileRTCPremeetingService *service = [[MobileRTC sharedRTC] getPreMeetingService];
if (service){
[service listMeeting];}

17.Listener for Pre-Meeting Service

Once Schedule/Edit/Delete/List meeting with MobileRTCPremeetingService, MobileRTCMobileRTC will return the event state by Pre-Meeting Service Delegate.

- (void)sinkSchedultMeeting:(NSInteger)result
NSLog(@"sinkSchedultMeeting result: %zd", result);
- (void)sinkEditMeeting:(NSInteger)result
NSLog(@"sinkEditMeeting result: %zd", result);
- (void)sinkDeleteMeeting:(NSInteger)result
NSLog(@"sinkDeleteMeeting result: %zd", result);
- (void)sinkListMeeting:(NSInteger)result withMeetingItems:(NSArray*)array
NSLog(@"sinkSchedultMeeting result: %zd items: %@", result, array);

18. App Share

The stack supports to start a meeting with sharing content in App(App Share), and at the same time the meeting UI can be hidden in the background while app sharing.

//Once meeting is started, user can sink “onMeetingReady” and start app share in this method
- (void)onMeetingReady{
MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if ([ms isDirectAppShareMeeting]){
if ([ms isStartingShare] || [ms isViewingShare]){
NSLog(@"There exist an ongoing share"); [ms showZoomMeeting:nil];
BOOL ret = [ms startAppShare]; NSLog(@"Start App Share... ret:%zd", ret);}

//Notify that user can share the splash in this method
- (void)onAppShareSplash{
MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if (ms){
[ms appShareWithView:self.splashVC.view];}

//Notify that user clicked the share button in meeting UI, user can hide meeting ui and share his/her content in the App.
- (void)onClickedShareButton{
MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if (ms){
if ([ms isStartingShare] || [ms isViewingShare]){
NSLog(@"There exist an ongoing share");
[ms hideMobileRTCMeeting:^(void){ [ms startAppShare];

//Notify that there exists no ongoing share, user can determine to share his/her content or not.
- (void)onOngoingShareStopped{
NSLog(@"There does not exist ongoing share");
MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if (ms){
[ms startAppShare]; }

19.Customize waiting UI

When the user tries to join a meeting which the host has not started, the “Waiting for Host” UI can be shown and your app can customize the waiting room UI once it receives the callback.

//This method is optional
- (void)onJBHWaitingWithCmd:(JBHCmd)cmd
switch (cmd) {
case JBHCmd_Show:
UIViewController *vc = [UIViewController new];
NSString *meetingID = [MobileRTCInviteHelper sharedInstance].meetingID;
vc.title = meetingID;
UIBarButtonItem *leaveItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Leave", @"") style:UIBarButtonItemStylePlain target:self ac- tion:@selector(onLeave:)];
[vc.navigationItem setRightBarButtonItem:leaveItem];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewCon- troller:vc];
nav.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentViewController:nav animated:YES completion:NULL];
case JBHCmd_Hide:
[self dismissViewControllerAnimated:YES completion:NULL];


Zoom iOS MobileRTC should be integrated in the main thread.

For fixing bug that view will move up about 20px after leaving meeting:

Add the following code in method “viewWillAppear” in the view controller which call the interface of starting/joining meeting

- (void)viewWillAppear:(BOOL)animated
[super viewWillAppear:animated];
//for bug that there exist 20 pixels in the bottom while leaving meeting quickly
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAni- mationNone];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAni- mationNone];


For keeping app continues to run in the background to support audio, add flag in project’s:


For Ignoring App Transport Security (ATS):

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app’s Info.plist file.


Note: NSAllowsArbitraryLoadsInWebContent will only work in iOS 10, and NSAllowsArbitrary- Loads will not work if added NSAllowsArbitraryLoadsInWebContent into Info.plist file.


For integrating RTC with Xcode8:

In Xcode8 and iOS 10.x, the app has crashed because it attempted to access privacy-sensitive data without a usage description. The app’s Info.plist must contain an NSCameraUsageDescrip- tion/NSMicrophoneUsageDescription/NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data.


For hiding warning from iOS MobileRTC:

Set “Debug Information Format” = “DWARF” in project’s build setting.

For customizing string resource in iOS MobileRTC:

Your app can define the string resource in Localizable.string file, and the key of string should be matched with the one in MobileRTC. On the other hand, the key and value of defined string should not be the same, or the customized string will not take place the one in MobileRTC.

We customized some strings in MobileRTCSample project, as follows:

"Waiting..." = "Sample Waiting...";
"Zoom" = "SDK Sample";
"Leave" = "Exit";
"Leave Meeting" = "Exit Meeting";


For customizing image resource in iOS MobileRTC:

Your app  can define the image resource by their own, and the image file name should be equal to the one in MobileRTC, which will take place the one in MobileRTC.

We customized some images in MobileRTCSample project, the name of image files as follows:
