静态方式

• 打开Info.plist文件
• 在对应UIApplicationShortcutItems关键字下添加item

动态方式

创建一个新的UIApplicationShortcutItem

• 初始化函数

  • -initWithType:localizedTitle:localizedSubtitle:icon:userInfo:
  • -initWithType:localizedTitle:

• 属性

  • localizedTitle:NSString
  • -localizedSubtitle:NSString
  • -type:NSString
  • -icon:UIApplicationShortcutIcon
  • -userInfo:NSDictionary
  • 只有只读特性，想要进行修改时，需要通过mutableCopy方法转变为 
    NSMutableApplicationShortcutItem

创建一个新的Item图标

• 初始化函数 
  
  • +iconWithType:
  • +iconWithTemplateImageName:
  • +iconWithContact:

当程序启动时

• 判断launchOptions字典内的UIApplicationLaunchOptionsShortcutItemKey是否为空
• 当不为空时,application:didFinishLaunchWithOptions方法返回false，否则返回true
• 在application:performActionForShortcutItem:completionHandler方法内处理点击事件
