(iphone) UIImageView setImage:泄漏? [英] (iphone) UIImageView setImage: leaks?

问题描述

我正在通过 [self setImage: newImage] 更改 UIImageview 的图像；

i'm changing image of UIImageview by [self setImage: newImage];

看起来每次我对 newImage 执行此操作时，似乎都没有发布之前的图像.
替换 UIImageView 的图像的正确方法是什么?

Looks like every time I does that with newImage, prior image doesn't seem to be released.
What's the correct way to replace image of UIImageView?

谢谢

推荐答案

UIImageView setImage: 永远不会泄漏，除非你传递的图像没有被释放.

UIImageView setImage: never leaks, unless the image you are passing doesn't get released.

如果您将自动发布的图像分配给图像视图，您的代码不会泄漏，如下所示.

Your code wont leak, if your are assigning an autoreleased image to the image view, something like the following.

UIImage *newImage = [UIImage imageNamed:@"sampleImage"];
[yourImageView setImage:newImage];

但是，如果您在某处分配图像，则必须手动释放它.

But, if you are allocating the image somewhere, you have to release it manually.
