for-in在循环15K次时消耗太多内存：OS-X应用程序

Question

When my loop runs for about 15k times too much memory is consumed. It's even going beyond 1 GB. What I am doing inside the loop is a series of Core data entity updating/creation. Is there any way I could control the memory usage?

Answer 1

Yes, you should use autorelease pools inside your loop. Here is the official Apple note about this, and if you use ARC in your project, this answer will be helpful.

Answer 2

使用自动释放池包装循环内容并不时将其耗尽。
