I did not do any setting before join meeting. The annotation button (like a pencil in a circle) should appear when others share screen. However it did not show no matter which version of ios sdk I use. And it does not work for all our ios devices. Also your sdk sample works on the same devices. Please tell me any possibilities about this. Thank you very much.

Hi Rex Is our sample work? but in your project not work. Our guess is that your account has turned off annotations on the web. Can you check it? Thanks ---

If the annotation is not turned off on the web Can you provide the SDK version, and then we will check it. Thanks ---

Hi Murray, It’s ON on the web. Same account same meeting works in your sample project and does not work in my project. I tried both versions 4.3.47201.0322 and 4.4.55968.0904. Are there any base requirement for the delegate o MobileRTCMeetingService? Thank you for your quick response. Rex ---

Looks like delete is not the key point. It still works in your project even I commented out the line: [self initDelegate]; in Line 42 of SDKStartJoinMeetingPresenter.m in your latest ios sdk sample project. Thanks, Rex ---

Hi Rex Can your debug with view hierarchy? and Check if the annotation is overridden by another view. ---

HI Murray, You are right, it’s overridden by other view. Now it works well in my project. Thank you very much. Rex ---

I have the same problem with the annotation button and tool bar disappearing. How do you override another view? I have no other windows open and have clicked on every menu, tab, and button on the zoom screen. I also can’t find anything that leads to anything called “view hierarchy.” Can you help? ---

Hi [goodwin](https://devforum.zoom.us/u/goodwin), Thanks for using Zoom SDK. Which SDK version are you using? Are you using Zoom default UI or Custom UI? The introduction of the view hierarchy can be found here: [https://developer.apple.com/library/archive/documentation/ToolsLanguages/Conceptual/Xcode\_Overview/ExaminingtheViewHierarchy.html](https://developer.apple.com/library/archive/documentation/ToolsLanguages/Conceptual/Xcode_Overview/ExaminingtheViewHierarchy.html) Thanks! ---
