问题 I've got a view controller showing a view with a UITextView, and I want to resize the view when the keyboard appears so that the UITextView isn't covered by the keyboard. I have this working correctly in almost all cases.

I did it using this extension that I found on stackoverflow while searching for the problem. struct AppUtility { static func lockOrientation(_ orientation: UIInterfaceOrientationMask) { if let delegate = UIApplication.shared

问题 Is there a simple way to disable screen rotation in Qt for whole app? I just don't want to worry about that and simply disable it. I am using Qt 5.8 and targeting Windows. 回答1: It's pointless, because screen rotation from your perspective is the same as a screen resolution change, and if you turn that off, your users will be rightly hating you. If you wish to test your code for compatibility with screen rotation, emulate it by changing screen resolution. 回答2: The best way would be to disable

问题 I have managed to create an android application to record videos but the problem is with the orientation of front camera video . The output is not the as per requirements . It gets automatically rotated . Application orientation is landscape . So, I need to record using front cam in landscape mode.
