I've integrated AVCam in my iOS app. The problem is in iPhone 4 the preview frame isn't fullscreen, it has empty side borders...

推荐答案

您需要使用AVCaptureVideoPreviewLayer的videoGravity属性.

看看

基于问询者建立的解决方案是:

Based on that the solution founded by the asker is:

- (void)setSession:(AVCaptureSession *)session {
    ((AVPlayerLayer *)[self layer]).videoGravity = AVLayerVideoGravityResizeAspectFill;
    ((AVPlayerLayer *)[self layer]).bounds = ((AVPlayerLayer *)[self layer]).bounds;
    [(AVCaptureVideoPreviewLayer *)[self layer] setSession:session];
}
