内存泄漏后，我把照片从UIImagePickerControllerSourceTypeCamera

Question

在我的应用我启动摄像头，让用户拍照：

UIImagePickerController *imagePickerControllerSubject = [[UIImagePickerController alloc] init]; 

    imagePickerControllerSubject.delegate = self; 

    imagePickerControllerSubject.sourceType = UIImagePickerControllerSourceTypeCamera; 

    [self presentModalViewController:imagePickerControllerSubject animated:YES]; 

而拍摄完成后，我得到了内存泄漏，你可以看到我Xcode Instrument的屏幕截图。

予分离的代码。我确定它来自相机，而不是我的应用程序，我没有在我的didFinishPickingImage函数中留下任何东西。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo 
    { 

      [picker dismissModalViewControllerAnimated:YES]; 

      return; 

    } 

我使用ARC，所以我并不需要释放imagePickerControllerSubject

这是在Xcode仪器

我使用最新版本的ios7

任何想法的截图？

感谢

我过去在这里我的视图控制器的整个代码。它不能更简单。不要忘记，我只能在iOS 7中使用这种内存泄漏，并且只能在摄像机类型中使用。

#import "FeedbackVC.h" 

    @interface FeedbackVC() 

    @end 

    @implementation FeedbackVC 

    - (IBAction)onClickTakePicture 
    { 

     NSLog(@"onClickTakePicture"); 

     imagePickerControllerSubject = [[UIImagePickerController alloc] init]; 

     imagePickerControllerSubject.delegate = self; 

     imagePickerControllerSubject.sourceType =    UIImagePickerControllerSourceTypeCamera; 

     [self presentModalViewController:imagePickerControllerSubject animated:YES]; 

    } 

    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo 
    { 


     picker.delegate = nil; 
     [self dismissViewControllerAnimated:NO completion:nil]; 
     picker = nil; 

     NSLog(@"imagePickerController"); 

    } 

    - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil 
    { 
     self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; 

     if (self) 
     { 
      // Custom initialization 
      if (self) 
      { 
       self.navigationItem.title = @"Feedback"; 

       self.title = @"Feedback"; 

       self.tabBarItem.image = [UIImage imageNamed:@"second"]; 
      } 

     } 


     return self; 
    } 

    - (void)viewDidLoad 
    { 
     [super viewDidLoad]; 

    } 

    - (void)didReceiveMemoryWarning 
    { 
      [super didReceiveMemoryWarning]; 
      // Dispose of any resources that can be recreated. 
    } 

    @end

在：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo 

尝试：

picker.delegate = nil 
[self dismissViewControllerAnimated:NO completion:nil]; 
picker = nil;
