Your app won't have access to the screen when the call is ringing. 通话响铃时，您的应用将无法访问屏幕。
- Press power and home buttons together to do a system screenshot? 同时按下电源和主页按钮以进行系统截图？
- Use the screenshots section in the Xcode Organizer to capture the screen while tethered? 使用Xcode Organizer中的屏幕截图部分来捕获屏幕时是否被束缚？
When a call is in progress you can press Home and re-open your app. 通话进行中，您可以按Home键并重新打开您的应用程序。
At that point you could use UIGraphicsBeginImageContext but it probably won't include the statusbar or green 'in progress' bar. 到那时，您可以使用UIGraphicsBeginImageContext但它可能不包括状态栏或绿色的“进行中”栏。
