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.
