Snippet-Xcode10快捷代码

迁移快捷代码

• 打开 Finder,快捷键Command + Shift + G.弹出文本框.输入~/Library/Developer/Xcode/UserData/CodeSnippets（如果没有CodeSnippets 可以先自定义一个代码段 然后文件自动生成 如果是beta版本路径所有改变了）

可以用cmd+shift+l调试出来

  代码段图.png

1.Title:标题
2.Summary:备注
3.Completion Shortcut:快捷方式
4.Platform:平台(iOS)、Language:语言(Objective-C)

5.Completion Scopes:作用域

作用域.png

• Class Implementation:类的实现区域（ViewDidLoad、ViewWillAppear同级）
• Class Interface Methods:类的定义区域（@property(nonatomic,strong)NSString *name;同级）
• Class Interface Variables:类定义区域的{}里面 定义常量({
  NSString *_name;
  } 同级)
  *Code Expression、Function or Method :都是在方法里面写
• Preprocessor Directive(前置处理器指示词):在一些导入类的头文件下面写
• String or Comment：不知道
• Top Level ：不知道

• 隐式<#name#> 就是Xcode里面 需要填充的占位
• 删除 选中按delete 就可以啦
