推荐答案

LLDB是苹果正在移动的LLVM工具套件包括铛。有很多改进的功能，包括改进的性能。这里有一个快速介绍GDB用户： http://lldb.llvm.org/tutorial.html

LLDB is part of the LLVM suite of tools that Apple is moving to, including Clang. There are tons of improved features, including improved performance. There's a quick intro for GDB users here: http://lldb.llvm.org/tutorial.html

但是...

您可能希望前往developer.apple.com的论坛。现在有一个关于LLDB问题的争论（在XCode 4.3.1）。一个令人讨厌的问题，来自苹果的人已经证实，是在观看ivars，而步进可能会告诉你错误的值。

You might want to take a trip over to the forums at developer.apple.com. There's a fair bit of rumbling about issues with LLDB at the moment (in XCode 4.3.1). One nasty issue, which people from Apple have confirmed, is that viewing ivars while stepping may show you the wrong values.
