## Enable the custom meeting UI

To use your custom meeting UI, enable it before you start or join a meeting.

```objectivec
[[MobileRTC sharedRTC] getMeetingSettings].enableCustomMeeting = YES
```

Once the custom meeting UI feature is enabled, then starting or joining
a meeting is the same:

### Start a meeting

```objectivec
{
#if 0
    //customize meeting title
    [ms customizeMeetingTitle:@"Sample Meeting Title"];
#endif
}

//Start a meeting
MobileRTCMeetingStartParam * param = nil;

// Check whether the user is logged in
if ([[[MobileRTC sharedRTC] getAuthService] isLoggedIn]) {
    MobileRTCMeetingStartParam4LoginlUser * user = [[[MobileRTCMeetingStartParam4LoginlUser alloc]init]autorelease];
    param = user;
    param.meetingNumber = kSDKMeetNumber; // if kSDKMeetNumber is empty, it's a instant meeting.
    param.isAppShare = appShare;
}
else
{
    //Sample: How to Get Token or ZAK via RestAPI
    NSString * token = [self requestTokenOrZAKWithType:MobileRTCSampleTokenType_Token];
    NSString * ZAK = [self requestTokenOrZAKWithType:MobileRTCSampleTokenType_ZAK];

    MobileRTCMeetingStartParam4WithoutLoginUser * user = [[[MobileRTCMeetingStartParam4WithoutLoginUser alloc]init] autorelease];
    user.userType = MobileRTCUserType_APIUser;
    user.meetingNumber = kSDKMeetNumber;
    user.userName = kSDKUserName;
    user.userToken = token;
    user.userID = kSDKUserID;
    user.isAppShare = appShare;
    user.zak = ZAK;
    param = user;
}
MobileRTCMeetError ret = [ms startMeetingWithStartParam:param];
return;
```

### Join a meeting

```objectivec
MobileRTCMeetingService *ms = [[MobileRTC sharedRTC] getMeetingService];
if (ms)
{
#if 0
    //customize meeting title
    [ms customizeMeetingTitle:@"Sample Meeting Title"];
#endif
    ms.delegate = self;

    //For Join a meeting with password
    NSDictionary *paramDict = @{
                                kMeetingParam_Username:kSDKUserName,
                                kMeetingParam_MeetingNumber:meetingNo,
                                kMeetingParam_MeetingPassword:pwd,
                                //kMeetingParam_ParticipantID:kParticipantID,
                                //kMeetingParam_WebinarToken:kWebinarToken,
                                //kMeetingParam_NoAudio:@(YES),
                                //kMeetingParam_NoVideo:@(YES),
                                };
//        //For Join a meeting
//        NSDictionary *paramDict = @{
//                                    kMeetingParam_Username:kSDKUserName,
//                                    kMeetingParam_MeetingNumber:meetingNo,
//                                    kMeetingParam_MeetingPassword:pwd,
//                                    };

    MobileRTCMeetError ret = [ms joinMeetingWithDictionary:paramDict];

    NSLog(@"onJoinaMeeting ret:%d", ret);
}
```

## Create a custom meeting UI

![](/img/1550619402240.png)

## Assign customized UI meeting delegate

To implement a custom meeting UI, firstly assign
`MobileRTCCustomizedUIMeetingDelegate` to your
`StartJoinMeetingPresenter` (Meeting View).

```objectivec
#import "SDKStartJoinMeetingPresenter.h"

@interface SDKStartJoinMeetingPresenter (CustomizedUIMeetingDelegate)<MobileRTCCustomizedUIMeetingDelegate>

@end
```

![](/img/1550619412576.png)

Then, in your `StartJoinMeetingPresenter.m` file, implement these two functions.

```objectivec
@implementation SDKStartJoinMeetingPresenter (CustomizedUIMeetingDelegate)

- (void)onInitMeetingView
{
  // Create & Present View Controller
  NSLog(@"onInitMeetingView....");

  CustomMeetingViewController *vc = [[CustomMeetingViewController alloc] init];
  self.customMeetingVC = vc;
  [vc release];

  [self.rootVC addChildViewController:self.customMeetingVC];
  [self.rootVC.view addSubview:self.customMeetingVC.view];
  [self.customMeetingVC didMoveToParentViewController:self.rootVC];

  self.customMeetingVC.view.frame = self.rootVC.view.bounds;
  ...
}

- (void)onDestroyMeetingView
{
  // Remove & Dismiss View Controller
  NSLog(@"onDestroyMeetingView....");

  NSLog(@"onDestroyMeetingView....");

  [self.customMeetingVC willMoveToParentViewController:nil];
  [self.customMeetingVC.view removeFromSuperview];
  [self.customMeetingVC removeFromParentViewController];
  self.customMeetingVC = nil;
  ...
}
```
