Xcode的誤差超過5個UIImages

Question

iPhone, 「More than maximum 5 filtered album lists trying to register. This will fail.」 Error

當我通過酥料餅的控制器或模態視圖控制器中添加圖片的UIImageViews，第4圖像後，當我去加入5日，Xcode的調試器輸出：「錯誤：超過最多5個過濾相冊列表試圖註冊，這將失敗「它仍然會讓我添加5張圖片，但只有4張圖片可以保存。我已經在這裏做了一些研究，並發現了這個問題，並且發現了這個問題： iOS 5 GM: <Error>: More than maximum 5 filtered album lists trying to register. This will fail

這裏的答案看起來好像它是Apple的一個錯誤，應該忽略它。那麼，蘋果通常會（修正）他們的Xcode bug，而且這已經有一段時間了，所以我開始懷疑真正的原因是什麼。我認爲這個錯誤與我的應用程序相關，最多隻能保存4張圖片。

這是我的工作代碼：

- (IBAction)grabImage { 
    self.imgPicker = [[UIImagePickerController alloc] init]; 
    self.imgPicker.delegate = self; 
    self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) { 
     _popover = [[UIPopoverController alloc] initWithContentViewController:imgPicker]; 
     [_popover presentPopoverFromRect:self.imageView.bounds inView:self.imageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; 
    } 

    else { 
     [self presentModalViewController:imgPicker animated:YES]; 
    } 
    [self.imgPicker resignFirstResponder]; 
} 
// Sets the image in the UIImageView 
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo { 
    if (imageView.image == nil) { 
     imageView.image = img; 

     [self.array addObject:imageView]; 

     [picker dismissModalViewControllerAnimated:YES]; 
     [self.popover dismissPopoverAnimated:YES]; 
     return; 

    } 

    if (imageView2.image == nil) { 
     imageView2.image = img; 
     NSLog(@"The image is a %@", imageView); 
     [self.array addObject:imageView2]; 

     [picker dismissModalViewControllerAnimated:YES]; 
     [self.popover dismissPopoverAnimated:YES]; 
     return; 
    } 

    if (imageView3.image == nil) { 
     imageView3.image = img; 

     [self.array addObject:imageView3]; 

     [picker dismissModalViewControllerAnimated:YES]; 
     [self.popover dismissPopoverAnimated:YES]; 
     return; 
    } 

    if (imageView4.image == nil) { 
     imageView4.image = img; 

     [self.array addObject:imageView4]; 

     [picker dismissModalViewControllerAnimated:YES]; 
     [self.popover dismissPopoverAnimated:YES]; 
     return; 
    } 
    if (imageView5.image == nil) { 
     imageView5.image = img; 

     [self.array addObject:imageView5]; 

     [picker dismissModalViewControllerAnimated:YES]; 
     [self.popover dismissPopoverAnimated:YES]; 
     return; 
    } 
} 

UPDATE：這裏是我當前的代碼：

- (IBAction)grabImage { 
    if (self.imgPicker == nil) { 
     self.imgPicker = [[UIImagePickerController alloc] init]; 
    } 

    self.imgPicker.delegate = self; 
    self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) { 
     _popover = [[UIPopoverController alloc] initWithContentViewController:imgPicker]; 
     [_popover presentPopoverFromRect:self.imageView.bounds inView:self.imageView permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; 
    } 

    else { 
     [self presentModalViewController:imgPicker animated:YES]; 
    } 
    [self.imgPicker resignFirstResponder]; 
}

從鏈接的其他問題，這聽起來像這是一個Apple bug，但與創建多個UIImagePickerController s有關。您一次只能呈現一個圖像選擇器控制器，因此也許您應該在第一次調用grabImage時創建一個，然後重複使用它，而不是每次都創建一個。
