iOS做自定義拍照的時候影象選擇90度，為了契合iPad的拍照

可以通過獲取AVCaptureConnection，然後呼叫setVideoOrientation:方法解決影象90°問題。 比如：顯示AVCaptureVideoPreviewLayer
[[_videoPreviewLayer
connection]
setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];
攝像，輸出用AVCaptureMovieFileOutput時，outputPic = [[AVCaptureStillImageOutput alloc]init]; AVCaptureConnection * videoConnection = [outputPic connectionWithMediaType:AVMediaTypeVideo]; [videoConnection setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];
outputMovie
= [[AVCaptureMovieFileOutput alloc] init];
AVCaptureConnection
* videoConnection = [outputMovie connectionWithMediaType:AVMediaTypeVideo];
[videoConnection
setVideoOrientation:AVCaptureVideoOrientationLandscapeRight];
