Hi: I am using zoom custom UI, implement the participants viewcontroller. I used to MobileRTCMeetingService class fuction [changeName: withUserID:] change participant screen name, but I don’t get callback event. Please tell me when perform “MobileRTCMeetingService changeName withUserID:” which method can invoke, then refresh UI. Example: I perform [MobileRTCMeetingService raiseMyHand], the [onMyHandStateChange delegate] can invoke. Thanks! ---

Hi @ios_feifei, Thanks for the post. We do not have such callback at the moment. We will add this in the next release. Hope this helps. Thanks! ---

Hi @carson.zoom, I’m using zoom custom UI.One question about meeting Settings is whether to change the screen name or not. I found default UI have this setup, but custom UI don’t have this setup. If custom UI need this setup, how to do that? I don’t found about change screen name property in “MobileRTCMeetingSettings.h”.Could you tell me what to do. Thanks! ---

Hi @carson.zoom, I’m using zoom custom UI. When my role is host, I call [MobileRTCMeetingService askUserStartVideo:] function let member open video,then member can invoke the following callback: > /\*! > @brief Callback event that host requests to unmute the user’s video. > \*/ > - (void)onSinkMeetingVideoRequestUnmuteByHost:(void (^\_Nonnull)(BOOL Accept))completion; When member completion(YES) can invoke host the “onSinkMeetingAudioStatusChange” function,then I refresh UI,but when member completion(NO) can invoke host which function? I used iOS sdk, version is [4.6.21666.0428](https://github.com/zoom/zoom-sdk-ios/releases/tag/v4.6.21666.0428).Thanks! ---

Hi @ios_feifei, Thanks for the reply. Regarding the callback `- (void)onSinkMeetingVideoRequestUnmuteByHost:(void (^_Nonnull)(BOOL Accept))completion;`, the default status is “mute”. When the host requests to unmute video, the callback `onSinkMeetingVideoRequestUnmuteByHost` will be triggered. - Selecting “accept” will return YES and unmute the video. And the host will trigger `(void)onSinkMeetingVideoStatusChange:(NSUInteger)userID; `. - Selecting “Decline” will return NO and will keep muted. It will not trigger any other callbacks. Hope this helps. Thanks! ---

Thanks @carson.zoom, I found zoom sdk demo, when host ask member open video,the member refused. Host can alert view, if not trigger any other callbacks , when appear this alert view . ![IMG_1691.PNG](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/0/0e2d0f2b1e8d06b9b8015e140039b662bde11732.jpeg) ---
