iOS-在UIImagePickerController CustomOverlayView中点击按钮后拍照

我也曾在类似的问题中寻找答案，但我尝试过的都没有成功。当我点击叠加视图中的任意一个按钮时，相机只对焦，不会触发任何动作。这是我的密码：

更新：前面的问题得到了回答-代码很好，我只是没有在testibuttonresponses方法中提醒自己。现在我想知道如何关闭相机并在UIImageView中显示捕获的图片

此外，UIImageView*DisplayedPhoto是在IB中制作的，因此它有一个框架

@interface CameraViewController ()
@property UIImagePickerController *PickerController;
@property (weak, nonatomic) IBOutlet UIImageView *DisplayedPhoto;
@end


- (UIView *)createCustomOverlayView
{

    // Main overlay view created
    UIView *main_overlay_view = [[UIView alloc] initWithFrame:self.view.bounds];

    // Clear view (live camera feed) created and added to main overlay view
    // ------------------------------------------------------------------------
    UIView *clear_view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height - self.HeightOfButtons)];
    clear_view.opaque = NO;
    clear_view.backgroundColor = [UIColor clearColor];
    [main_overlay_view addSubview:clear_view];
    // ------------------------------------------------------------------------


    // Creates the buttons on the bottom of the view (on top of the live camera feed)
    // Then adds the buttons to the main overlay view
    // ------------------------------------------------------------------------
    for(int i = 0; i < 2; i++) {
        UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
        // when a button is touched, UIImagePickerController snaps a picture
        [button addTarget:self action:@selector(testIfButtonResponds) forControlEvents:UIControlEventTouchUpInside];
        button.frame = CGRectMake( i * self.view.frame.size.width / 2, self.view.frame.size.height - self.HeightOfButtons, self.view.frame.size.width / 2, self.HeightOfButtons);
        [button setBackgroundColor:[UIColor redColor]];
        [main_overlay_view addSubview:button];
    }
    // ------------------------------------------------------------------------

    return main_overlay_view;
}

- (void)makeCustomCameraAppear
{
    self.PickerController = [[UIImagePickerController alloc] init];
    self.PickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    self.PickerController.showsCameraControls = NO;
    self.PickerController.delegate = self;

    UIView *overlay_view = [self createCustomOverlayView];
    [self.PickerController setCameraOverlayView:overlay_view];

    [self presentViewController:self.PickerController animated:YES completion:NULL];
}

- (void)viewDidAppear:(BOOL)animated
{
    [self makeCustomCameraAppear];
}

- (void) testIfButtonResponds
{
    [self.PickerController takePicture];
    [self.PickerController dismissViewControllerAnimated:YES completion:nil];
}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage *chosen_image = info[UIImagePickerControllerEditedImage];
    self.DisplayedPhoto.image = chosen_image;
    [self.PickerController dismissViewControllerAnimated:YES completion:NULL];
}

@interface-CameraViewController（）
@属性UIImagePickerController*PickerController；
@属性（弱，非原子）IBUIImageView*DisplayedPhoto；
@结束
-（UIView*）创建自定义覆盖视图
{
//已创建主覆盖视图
UIView*main_overlay_view=[[UIView alloc]initWithFrame:self.view.bounds]；
//创建并添加到主覆盖视图的清除视图（实时摄影机馈送）
// ------------------------------------------------------------------------
UIView*clear_view=[[UIView alloc]initWithFrame:CGRectMake（0,0，self.view.frame.size.width，self.view.frame.size.height-self.HeightOfButtons）]；

clear_view.backgroundColor=[UIColor clearColor]；
[主覆盖视图添加子视图：清除视图]；
// ------------------------------------------------------------------------
//在视图底部（实时摄影机提要顶部）创建按钮
//然后将按钮添加到主覆盖视图中
// ------------------------------------------------------------------------
对于（int i=0；i<2；i++）{
UIButton*button=[UIButton button类型：UIButtonTypeCustom]；
//触摸按钮时，UIImagePickerController会捕捉图片
[按钮添加目标：自我操作：@selector（TestifButtonResponses）forControlEvents:UIControlEventTouchUpInside]；
button.frame=CGRectMake（i*self.view.frame.size.width/2，self.view.frame.size.height-self.HeightOfButtons，self.view.frame.size.width/2，self.HeightOfButtons）；
[按钮设置背景颜色：[UIColor REDCLOR]]；
[主覆盖视图添加子视图：按钮]；
}
// ------------------------------------------------------------------------
返回主覆盖视图；
}
-（无效）使CustomCamera出现
{
self.PickerController=[[UIImagePickerController alloc]init]；
self.PickerController.sourceType=UIImagePickerControllerSourceTypeCamera；
self.PickerController.showsCameraControls=否；
self.PickerController.delegate=self；
UIView*overlay_view=[self-createCustomOverlayView]；
[self.PickerController setCameraOverlayView:覆盖视图]；
[self-presentViewController:self.PickerController动画：是完成：空]；
}
-（无效）视图显示：（BOOL）动画
{
[自行制作自定义摄像机]；
}
-（无效）测试按钮响应
{
[self.PickerController拍摄照片]；
[self.PickerController dismissViewControllerAnimated:YES完成：nil]；
}
-（void）imagePickerController:（UIImagePickerController*）picker未使用信息完成PickingMediaWithInfo:（NSDictionary*）信息
{
UIImage*所选图像=信息[UIImagePickerControllerEditedImage]；
self.DisplayedPhoto.image=所选图片；
[self.PickerController dismissViewControllerAnimated:是完成：NULL]；
}

您可以发布方法的代码：

testibuttonresponses

？它被调用了吗？啊，你是对的，它被调用了，但我的方法没有提醒我。谢谢我仍然无法使用其中一个按钮拍照，因此我将更新代码以显示我正在尝试的内容。只需更新

imagePickerController:didFinishPickingMediaWithInfo

中的代码，您必须执行

[自我解除视图控制器：是完成：无]，而不是[self.PickerController。。。
