I’m pretty sure this is just a bug in iOS 8.0. It’s reproducible with the simplest of POC apps that does nothing more than attempt to present a UIImagePickerController like you’re doing above. Furthermore, there’s no alternative pattern to displaying the image picker/camera, to my knowledge. You can even download Apple’s Using UIImagePickerController sample app, … Read more

I found that in iOS 8.0.2 iPad does not seem to have that bug but iPhone still does.

The problem in iOS7 has to do with transitions. It seems that if a previous transition didn’t complete and you launch a new one, iOS7 messes the views, where iOS6 seems to manage it correctly. You should initialize your Camera in your UIViewController, only after the view has Loaded and with a timeout: – (void)viewDidAppear:(BOOL)animated … Read more
Check the AVAuthorizationStatus and handle the cases properly. NSString *mediaType = AVMediaTypeVideo; AVAuthorizationStatus authStatus = [AVCaptureDevice authorizationStatusForMediaType:mediaType]; if(authStatus == AVAuthorizationStatusAuthorized) { // do your logic } else if(authStatus == AVAuthorizationStatusDenied){ // denied } else if(authStatus == AVAuthorizationStatusRestricted){ // restricted, normally won’t happen } else if(authStatus == AVAuthorizationStatusNotDetermined){ // not determined?! [AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) { … Read more
