iOS 5:UIImagePickerController崩溃

Question

我UIImagePickerController在iOS 5中遇到问题.

我的应用程序是开发的,iOS4.3但现在我正在升级到iOS5.

当我尝试从照片库中选择图像时,我的应用程序崩溃了.

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

我使用以下代码UIImagePickerController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];   

 }

我有搜查,我发现很多链接LIKE1,LIKE2,LIKE3,样4 和like5.

但这些都不包含任何适当的解决方案.

我该怎么办 ？
