_picker = [[UIImagePickerController alloc] init];
_picker.sourceType = UIImagePickerControllerSourceTypeCamera;

_picker.cameraCaptureMode = UIImagePickerControllerCameraCaptureModePhoto;

_picker.allowsEditing = YES;

and viewWillApper method:

    -(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(closeCameraButton:) name:@"ShowMainView" object:nil];
    [self createImagePicker];
    [m_cameraOverlayView setBackgroundColor:[UIColor clearColor]];
    [self presentModalViewController:_picker animated:NO];
    _picker.cameraOverlayView = m_cameraOverlayView;

    [cameraImgView setHidden:YES];
    [filterView setHidden:YES];
    m_cameraOverlayView.hidden = NO;
    cameraSelectedButton.hidden = NO;
    cancelButton.hidden = YES;
    selectButton.hidden = YES;

    for (id Object in [scrollview subviews])
    {
        if([Object isKindOfClass:[UIButton class]])
        {
            [Object removeFromSuperview];
        }
    }

    [m_toolbarImage setFrame:CGRectMake(0, 427, 320, 55)];
    [cameraSelectedButton setFrame:CGRectMake(128, 432, 86, 44)];

    [m_cancelButton setFrame:CGRectMake(10, 434, 82, 40)];
    [m_cancelButton setTitle:@"Close" forState:UIControlStateNormal];
    [m_cancelButton setBackgroundImage:[UIImage imageNamed:@"menu-bar-button.png"] forState:UIControlStateNormal];
    [m_cancelButton setTitleColor:[UIColor colorWithRed:110/256.0 green:52/256.0 blue:28/256.0 alpha:1.0] forState:UIControlStateNormal];


    [cancelButton setFrame:CGRectMake(120, 434, 35, 35)];
    [selectButton setFrame:CGRectMake(184, 434, 35, 35)];

    }

推荐答案

这似乎无论是否使用ARC，iOS 5中的UIImagePickerController都会出现问题。

This seems to be a problem with UIImagePickerController in iOS 5 whether using ARC or not.

我有一个使用xcode 3.2.5为iOS 4开发的应用程序，当从图书馆拍摄或选择照片时，仪器显示没有泄漏（在运行的设备上测试） iOS 4.1）。在运行iOS 5.1的设备上测试的相同代码如上所述泄漏。

I have an app developed for iOS 4 using xcode 3.2.5 and Instruments shows no leaks when a photo is either taken or selected from the library (tested on a device running iOS 4.1). The same code tested on a device running iOS 5.1 leaks as described.

我知道这不是一个答案，但问题似乎比原始问题更广泛。

I know this isn't an answer but the problem seems broader than the original question.
