UITableView内存泄漏imageWithContentsOfFile

Question

我正在泄漏内存在我的UITableView为标准图像/文本视图。我正在加载一个图像imageWithContentsOfFile，并将其分配给我的cell的imageView.image。

该图像不会被自动释放，我不得不重复的细胞在-dealloc方法，并将其设置为0。

但我每次还是失去记忆我显示我UITableView，我真的不知道为什么。我也从单元中删除autorelease，并试图手动释放它，但我仍然失去记忆。

Answer 1

如果内存泄漏，可能原因将与阵列_profils.profils。或者你可以像分配和释放图像一样，

NSString *path=[LibTools documentsSubFolder:cpp._subFolder]; 
UIImage *cellImage = [[UIImage alloc] initWithContentsOfFile:[path stringByAppendingPathComponent:cpp._imageName]]; 
cell.imageView.image =cellImage; 
[cellImage release];

谢谢你们，我找到了以前的观点泄漏，现在一切工作没有任何的dealloc代码...
