如何释放由CGImageCreateWithImageInRect关联的内存 [英] How to release memory associated by CGImageCreateWithImageInRect

问题描述

我正在使用 CGImageCreateWithImageInRect（）从背景图像运行时生成一个小图像，该图像将在每次线程调用时显示（0.01秒）。一旦我开始通过 CGImageCreateWithImageInRect 应用程序显示图像的一部分，就会开始以很高的速度消耗内存并在几秒钟内崩溃。消耗的内存超过20 MB，并且崩溃。普通应用程序将在2MB上运行。

I am using CGImageCreateWithImageInRect() for generating a small image from a background image runtime, which is going to displayed for every thread call (0.01 sec). Once I start showing part of image through CGImageCreateWithImageInRect application starts consuming memory in very high rate and crashes within seconds. Memory consumed goes to 20+ MB and crashes. Normal application would run on 2MBs.

Image1 = CGImageCreateWithImageInRect(imageRef, CGRectMake(x, y, w, h));

，经过处理后，我会这样做

and after processing I do

CGImageRelease(Image1);

但这对我没有帮助。

我想知道如何释放与 CGImageCreateWithImageInRect 相关的内存。

I want to know how to release memory associated with CGImageCreateWithImageInRect.

推荐答案

您问题的答案实际上是CGImageRelease；您从代码中摘录的那对线是正确平衡的。您一定是在其他地方泄漏。

The answer to your question is in fact CGImageRelease; the pair of lines you have excerpted from your code are correctly balanced. You must be leaking somewhere else.
