使用xcodebuild命令行在共享构建机器上进行干净的构建:

cd project_directory
xcodebuild -configuration Release -alltargets clean
xcodebuild -configuration Release -alltargets

使用类浏览器显示继承的方法

Apple's API reference documentation does not show methods inherited from a superclass. Sometimes, though. it's useful to be able to see the full range of functionality available for a class -- including a custom class of your own. You can use the Class Browser (from the Project menu) to display a flat or hierarchical list of all the classes related to a current project. The upper pane on the right hand side of the browser window shows a list of methods associated with the object selected in the browser. You can use the Configure Options sheet to select "Show Inherited Members" to show inherited methods as well as those defined by the selected class itself. You click the small book symbol to go to the corresponding documentation.

构建成功/失败噪音;从术语:

defaults write com.apple.Xcode PBXBuildSuccessSound ~/Library/Sounds/metal\ stamp.wav
defaults write com.apple.Xcode PBXBuildFailureSound ~/Library/Sounds/Elephant

CTRL + Alt +⌘+ r清除日志

⇧⌘。它会构建和分析，这意味着Xcode会警告你可能的泄漏。

使用^T来交换前面两个字母

这适用于所有Cocoa应用程序，但我尤其喜欢在编码时使用它。使用^T (Control-T)来交换插入符号旁边的两个字母，或者当插入符号在末尾时，交换插入符号前面的两个字母。例如:

fi^T

．.． 就变成:

if

．.． 这是我经常犯的错别字。
