Continuing the discussion from [Can't use the appShareWithView](https://devforum.zoom.us/t/cant-use-the-appsharewithview/56311/25):

Since the post had been locked. I create a new one.

I double-check the SDK reference ([https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/in-meeting-function/screen-share](https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/in-meeting-function/screen-share))

I found that there are to type of sharing.

1. Screen Broadcast with ReplayKit.
2. share Single UIView

What I want to do should be the second one. As a result, I didn’t add the screenShare framework to my Xcode project. Is it the reason why I called the method but have nothing happened?

And I found that if need to use the appShareWithView, it needs the enable the Custom Meeting UI, is that need if we are using [ms meetingView], this function will not be able to use?

For your information, actually, I want to do the function is like the Zoom app, just share a picture with the participants.

Hey @lemon97213,

Thanks for using the dev forum!

Yes you can use this in default UI actually. Try this code before calling appShareWithView:  
MobileRTCMeetingService \*ms = [[MobileRTC sharedRTC] getMeetingService];  
if (ms) {  
if (ms.isStartingShare) {  
[ms stopAppShare];  
} else {  
[ms startAppShare];  
}  
}

Thanks!  
Michael

So I don’t need the “Replaykit” ?

Hey @lemon97213,

Does this happen with other UIViews besides the meetingView?

Thanks!

@Michael_Condon  
Sorry, I am not very understanding. i tried to add this in different function, it is still don’t work. And The app now only have one view which is the meetingview while the meeting started.
