崩潰在self.view presentviewcontroller：UIImagePickerController在iOS 6

當我嘗試從xcode 4.5調用相冊時，應用程序崩潰。注意：我將應用程序方向設置爲橫向模式。在你的邏輯崩潰在self.view presentviewcontroller：UIImagePickerController在iOS 6

UIImagePickerController *picker=nil; 
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum]) 
{ 
    picker = [[UIImagePickerController alloc] init]; 
    picker.delegate = self; 
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 

    picker.allowsEditing = NO; 
    picker.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType: 
      UIImagePickerControllerSourceTypeSavedPhotosAlbum]; 

} 

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { 
    [self presentViewController:picker animated:YES completion:nil]; 
}

該代碼位於視圖控制器中？ –

什麼是異常/錯誤/崩潰的樣子？ –

你能更具體嗎？當第二個陳述達成時，你如何確信第一個陳述是真實的？當你打電話給presentViewController :::你怎麼能確定picker不是零？ –

的一個錯誤是，如果isSourceTypeAvailable;否在iPhone上，你會嘗試提出一個控制器，這是nil。
