了解Xcode中的仪器，测试泄漏

问题描述

我刚刚开始使用仪器，这是一个很好的小工具来测试内存分配/泄漏以及所有好东西。但是我很迷惑于它的工作原理... Ive寻找解释如何使用它的教程，但没有教程解释如何处理它。

我我会尝试解释一下：每当我运行我的Xcode应用程序时，我都会设置它，仪器跟踪一切。但是仪器记录的东西对我来说是没有意义的。

发现一个泄漏，之后它开始泄漏字节。它表示泄漏的对象是_NSCFString和其他类似的东西。这是一个截图

我的问题是，我该如何解释？如果有一个教程解释这个，请留下一个答案，或解释给我。

解决方案

最好的了解如何使用仪器的方法是观看iOS开发基础/高级/基础视频以及WWDC会议视频。

您可以找到一个列表苹果公司的，需要iOS开发者帐户，通常通过iTunes托管。

I just started using Instruments, a nice little tool for testing memory allocations/ leaks and all that great stuff. But I'm pretty confused at how it works... Ive looked for tutorials explaining how to work with it, but no tutorials explained what to do with it.

I'll try to explain this: I have it set up to whenever I run my Xcode app, Instruments tracks everything. But the stuff that instruments record makes no sense to me.

There was one leak discovered, and after that it started leaking bytes. It says the leaked object is _NSCFString and some other stuff like that. Here is a screenshot

My question is, how do I interpret this? If there is a tutorial out there that explain this, please leave as an answer, or explain it to me.

解决方案

The best way to learn how to use Instruments is to watch the iOS Development Essential/Advanced/Foundation videos as well as the WWDC session videos on the topic.

You can find a list at Apple's Development Video Access which will require an iOS Developer Account and are usually hosted through iTunes.
