OP写道：

以下是解决方案：

我有两个UIViewController。主ViewController和CustomOverlay（用于摄像机控件）。

我是ViewController我声明了源类型和可能相机控制的叠加，如下所示：

- (void)viewDidLoad
{
    // notification from the CustomOverlay Controller that triggers the eTakePicture method
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(eTakePicture:) name:@"eTakePicture" object:nil];

    daysBtn.delegate = self;
    daysBtn.hidden = YES;

    picker = [[UIImagePickerController alloc] init];
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.cameraDevice = UIImagePickerControllerCameraDeviceFront;
    picker.showsCameraControls = NO;
    picker.navigationBarHidden = YES;
    picker.wantsFullScreenLayout = YES;
    picker.delegate = self;

    overlay = [[CustomOverlay alloc] initWithNibName:@"CustomOverlay" bundle:nil];
    // Overlay for the camera controls, note the "= overlay.view", the ".view" was important
    // because the overlay is a new UIViewcontroller (with xib) so you have to call the
    // view. Most tutorials that I saw were based on UIView so only "= overlay" worked.
    picker.cameraOverlayView = overlay.view;
    [self presentModalViewController:picker animated:NO];

    [super viewDidLoad];
}

现在在CustomOverlay上，这是一个UIViewController我有拍照按钮，并希望这个按钮触发主ViewController中的方法：

- (IBAction)shoot:(id)control {

    [[NSNotificationCenter defaultCenter] postNotificationName:@"eTakePicture" object:self];

}

回到主ViewController：

-(void)eTakePicture:(NSNotification *)notification
{
    [picker takePicture];
}

一旦我查看，上面的所有代码都会改变一点，特别是我必须要检查cameraSourceType是否可用的第一个块。

希望能帮到那里的人。有问题，请问。
