什么是Objective-C调试提示？ [英] What are some Objective-c debugging tips?

问题描述

我仍然没有正确学习如何使用Xcode调试器，但我想知道是否有人有一些最喜欢的调试提示，你可以快速插入代码来查看对象的状态。任何有助于我更好地掌握Objective-c内部的东西。

我主要依靠 NSLog（@％@ ，myObject），以查看myObject发生了什么，或者有时候 NSLog（@％@，[myObject class]）真的应该是班级。我知道我可以通过使用调试器来做到这一点，但是我想在使用完整的调试器之前先尝试使用代码。

你有类似的技巧吗？

解决方案

Asserts。很多很多的断言。当你认为某事必须是某种方式时，断言这是真的。

Build&分析是新的Build。在雪豹中使用Clang Static Analyzer。

没有魔法;您的系统和代码中的所有内容都出于某种原因，包括崩溃和不正当行为。

拥抱调试器;这是真的很强大，很容易开始使用。

I'm still haven't properly learned how to use the Xcode debugger, but I was wondering if anyone has some favourite debugging tips, things you can quickly insert into code to see the state of objects. Anything which would help me get more of a grasp on the internals of Objective-c.

Mostly I rely on NSLog(@"%@", myObject) to see what's happening with myObject, or sometimes NSLog(@"%@", [myObject class]) to check that something is really the class it should be. I know that I can do both by using the debugger, but I want to try using code for the moment, before I take the leap into using a full debugger.

Do you have any similar tricks?

解决方案

Asserts. Lots and lots of asserts. When you assume something must be some way, assert that it is true.

Build & Analyze is the new Build. Use the Clang Static Analyzer in Snow Leopard.

There is no magic; everything on your system and in your code happens for a reason, including crashes & misbehavior.

Embrace the debugger; it is really powerful and quite easy to start using.
