xcode 設置快捷鍵 整行上下移動

設置整行代碼上下移動：
找到Xcode中的自帶的配置文件：
/Applications/Xcode.app/Contents/Frameworks/IDEKit.framework/Versions/A/
Resources/IDETextKeyBindingSet.plist
用文本編輯IDETextKeyBindingSet.plist，並添加如下代碼：

 

 1     <dict>
 2         <key>GDI Duplicate Current Line</key>
 3         <string>selectLine:, copy:, moveToEndOfLine:,insertNewline:, paste:, deleteBackward:</string>
 4         <key>GDI Delete Current Line</key>
 5         <string>moveToEndOfLine:, deleteToBeginningOfLine:,deleteBackward:,moveDown:,moveToEndOfLine:</string>
 6         <key>GDI Move Current Line Up</key>
 7         <string>selectLine:, cut:, moveUp:, moveToBeginningOfLine:, insertNewLine:, paste:, moveBackward:</string>
 8         <key>GDI Move Current Line Down</key>
 9         <string>selectLine:, cut:, moveDown:, moveToBeginningOfLine:, insertNewLine:, paste:, moveBackward:</string>
10         <key>GDI Insert Line Above</key>
11         <string>moveUp:, moveToEndOfLine:, insertNewline:</string>
12         <key>GDI Insert Line Below</key>
13         <string>moveToEndOfLine:, insertNewline:</string>
14     </dict>

這個dict是一組能夠設置快捷鍵的操做，裏面的key是名稱，對應的string是對應的一組操做
GDI Duplicate Current Line    複製當前行到下面一行
GDI Delete Current Line 刪除當前行
GDI Move Current Line Up 把當前行往上移動一行
GDI Move Current Line Down 把當前行往下移動一行
GDI Insert Line Above 在當前行上面增長一空行
GDI Insert Line Below 在當前行下面增長一空行（無論光標是否在行尾）

3. 重啓Xcode，在Xcode菜單中，打開Preferences，選中Key Binding，在右上方搜索GDI：
