我运行了分配工具,我肯定有一个保留周期,阶梯状的图表是一个死的赠品。但是,我是 iOS 编程的新手,甚至在通过互联网筛选文档后也不知道如何解决我的保留周期问题。据我所知,有一些强引用阻止未使用的内存在我的 ARC 项目中被释放。该应用程序是一个简单的音板,但内容很多,这就是为什么我以前不必处理这个问题。内存现在是一个真正的问题。对于 ViewController.m,我有

这只是代码的一部分,因为其余部分相当庞大,并且基本上是同一行代码,只是对其引用的文件进行了微小的更改。我的问题是我究竟该如何修复保留周期?这与我的模态转换有关吗?因为这就是导致仪器内存分配异常和我的 native iOS 设备崩溃的原因。
最佳答案
在我看来,您确实没有保留周期。听起来您正在其他 View Controller 之上呈现一系列永无止境的 View Controller 。
使用模态呈现或导航 Controller 推送具有类似的效果:先前的 View Controller 被新 View Controller 覆盖但未被释放。
您没有发布任何显示如何从 View Controller 导航到 View Controller 的代码,因此很难说出您到底在做什么。
如果你想从 View Controller A 到 View Controller B 再到 View Controller C,然后返回到 A,你需要从 A 到 B,然后从 B 到 C,但是为了返回而关闭,而不是呈现 View Controller A 的新副本。
