iOS 5：UIImagePickerController 崩溃

Question

我在 iOS 5 中遇到了UIImagePickerController 的问题。

我的应用是在iOS4.3 开发的，但现在我将其升级到iOS5。

当我尝试从照片库中选择图片时，我的应用程序崩溃了。

它在带有EXE_BAD_ACCESS 的 main.m 文件中崩溃，并且没有给出任何崩溃日志。

我正在使用UIImagePickerController 的以下代码从照片库中选择图像。

-(IBAction) photoLibraryAction {
    if ([self isPad]) {

    UIImagePickerController* picker = [[UIImagePickerController alloc] init]; 
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    picker.delegate = self; 

    UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker];
    self.popoverController = popover; 
    //[popover release];
    [popoverController presentPopoverFromRect:CGRectMake(btnLibraryPic.frame.origin.x, btnLibraryPic.frame.origin.y, btnLibraryPic.frame.size.width, btnLibraryPic.frame.size.height) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];


    //[picker release];
}else {
    ipc=[[UIImagePickerController alloc] init];
    ipc.delegate=self;

    ipc.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;

    [self presentModalViewController:ipc animated:YES];
} 
}


 #pragma mark - Image Picker Delegate
 -(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
  {
 [[picker parentViewController] dismissModalViewControllerAnimated:YES];
 [picker release];
  }



-(void) imagePickerController:(UIImagePickerController *) picker didFinishPickingMediaWithInfo :(NSDictionary *)info
{   

imgV.image =[info objectForKey:UIImagePickerControllerOriginalImage];

if ([self isPad]) {
    [popoverController dismissPopoverAnimated:YES];
}

[[picker parentViewController] dismissModalViewControllerAnimated:YES];

[picker release];   

 }

我在 SO 上进行了搜索，发现很多链接 like1、like2、like3、like4 和like5。

但这些都不包含任何适当的解决方案。

我该怎么办？
