您需要创建一个 CustomOverlayView。然后像这样配置你的选择器:

    overlay = [[CustomOverlayView alloc]initWithFrame:self.view.bounds];
    overlay.delegate = self;
    picker = [[UIImagePickerController alloc]init];
    picker.delegate = self;
    picker.navigationBarHidden = YES;
    picker.toolbarHidden = YES;
    picker.wantsFullScreenLayout = YES;
    picker.allowsEditing = YES;
    if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]){

        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    }
    else{
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    }
    picker.showsCameraControls = NO;
    picker.cameraOverlayView = overlay;
