使用.xib文件作为自定义相机overlayview

Question

我创建了一个带有.xib文件的CameraOverlayViewController来实现自定义的相机overlayView。 overlayView只是一个透明背景，带有一个按钮，用于从photoLibrary中选择照片，并使用以下代码在mainViewController中成功加载：

CameraOverlayViewController* overlay = [[CameraOverlayViewController alloc] initWithNibName:@"CameraOverlayViewController" bundle:nil];
cameraPicker.cameraOverlayView = overlay.view;

然而，当我按下cameraOverlayView上的按钮时没有任何反应。没有错误消息，没有。有谁知道这里发生了什么？下面是我在CameraOverlayViewController文件中的代码：

- (IBAction)select:(UIButton *)sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    [self dismissViewControllerAnimated:YES completion:^{

        [self presentViewController:picker
                           animated:YES completion:nil];

    }];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

    [self presentViewController:picker animated:YES completion:NULL];
    NSLog(@"Just work alrdy!!!");
}

提前致谢！

试试这个..

-(IBAction)select:(UIButton *)sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.allowsEditing = YES;
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self dismissViewControllerAnimated:YES completion:^{

    [self presentViewController:picker
                       animated:YES completion:nil];  ////////check this is called??????

    }];
}
