iOS内存在app中不断增加，看似无缘无故

Question

这是我的应用程序的入口视图控制器。

它开始使用大约6.5mb的内存，然后以每秒约0.1mb的速度持续攀爬。

究竟我做错了什么？

我认为没有任何理由可以让这些代码不断泄漏，特别是每次都运行一次。

此外，删除大部分内容似乎没有帮助。想法？

问题是你已经打开了僵尸。造成泄密正是僵尸所做的！ （“僵尸做什么”似乎错了......）它的全部目的是防止物体被释放。当zombies（是？）打开时，你永远不应该检查内存使用情况。

Answer 2

两个建议，

1. 尝试替换

   SKView * skView = (SKView *)self.view; 
   

   带

   __weak SKView * skView = (SKView *)self.view;
   

2. 将以下代码保留在if条件之外。

   [super viewWillLayoutSubviews];
