当你使用“单窗口布局”时，回到编辑器必须点击工具栏，这很烦人(加上你以后需要“删除细节窗格”)。

上面的快捷方式做到了这一点，并让您准备好编写代码。

“Ctrl+左/右箭头”进行字内文本导航。我使用这个特性将光标从变量中的一个“驼峰”跳转到下一个。

Cmd+Option+O to open a file in a separate window. Can configure Tab to always indent. I frequently use it to indent an entire file. Ctrl+Arrow keys to move between camel case words.

This helps me focus on API available only on a particular iOS/Mac version of the SDK. Cmd+Shift+A to build and analyze.

一些技巧可以在Xcode Tools tips中找到。

当您在一个方法上使用代码完成，并且它有多个参数时，使用CTRL + /移动到下一个需要填充的参数。
