被釋放的指針未被分配。複雜的malloc歷史幫助

iPhone - debugging "pointer being freed was not allocated" errors

但malloc_history真的扔我爲一個循環，任何人都可以闡明以下任何光線：

你的問題是什麼？ – 2010-04-21 21:31:33

我不知道哪個指針可以釋放兩次，在那裏我只能看到selectedPhoto，而且我無法在我的項目中的任何地方找到它... 也不應該有更多的自由語句ALLOC的？ – 2010-04-22 00:21:51

您可以使用XCode的「構建和分析」功能。它位於「Build」下的菜單中。也許這個分析儀會給你一個提示。

分析告訴我有兩個我沒有發佈的變量，但是當我修復這些變量時沒有其他見解，並且錯誤仍在控制檯中報告。 – 2010-04-22 17:15:26

你在做CoreAnimation或者UIImagePickerController嗎？ – schaechtele 2010-04-23 07:03:25

我在我的代碼中有一個UIImagepickerController，當它被解散時，控制檯顯示錯誤。 – 2010-04-23 12:55:25

我正在初始化UIIMagePickerController如下，另一種方法是接受結果。

-(void)addImage{ 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];  

    if (![UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) { 
     return; 
    } 

    if(photoPicker == NULL) { 
     photoPicker = [[UIImagePickerController alloc] init]; 
     photoPicker.delegate = self; 
     photoPicker.allowsImageEditing = NO; 
    } 

    photoPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 

    [self presentModalViewController:photoPicker animated:YES]; 
    [pool release]; 
}

似乎這是舊版本模擬器中的uiimagepicker的問題，更改爲> 3.0版本會消除警告消息。 – 2010-04-25 19:51:38
