Shortcutitem static mode

• Open Info.plist File
• Add item under the corresponding Uiapplicationshortcutitems keyword

Dynamic ModeModify a Shortcutitem of the current application

  //获取第0个shortcutItem    id oldItem = [existingShortcutItems objectAtIndex: 0];    //将旧的shortcutItem改变为可修改类型shortcutItem    id mutableItem = [oldItem mutableCopy];    //修改shortcutItem的显示标题    [mutableItem setLocalizedTitle: @“Click Lewis”];

gets the shortcutitems of the current application

  //获取当前应用程序对象    UIApplication *app = [UIApplication sharedApplication];    //获取一个应用程序对象的shortcutItem列表    id existingShortcutItems = [app shortcutItems];

Resets the shortcutitems of the current application

  //根据旧的shortcutItems生成可变shortcutItems数组    id updatedShortcutItems = [existingShortcutItems mutableCopy];    //修改可变shortcutItems数组中对应index下的元素为新的shortcutItem    [updatedShortcutItems replaceObjectAtIndex: 0 withObject: mutableItem];    //修改应用程序对象的shortcutItems为新的数组    [app setShortcutItems: updatedShortcutItems];

Create a new Uiapplicationshortcutitem

• initialization function

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

• Property

  • localizedTitle:NSString

  • - localizedSubtitle:NSString

  • - type:NSString

  • - icon:UIApplicationShortcutIcon

  • - userInfo:NSDictionary

  • Only read-only features, if you want to make changes, need to go through the Mutablecopy method to change to
    Nsmutableapplicationshortcutitem

Create a new Item icon

• initialization function

  • + iconWithType:

  • + iconWithTemplateImageName:

  • + iconWithContact:

When the program starts

• Determines whether the Uiapplicationlaunchoptionsshortcutitemkey in the Launchoptions dictionary is empty
• When not empty, the Application:didfinishlaunchwithoptions method returns FALSE, otherwise returns true
• Handling Click events within the Application:performActionForShortcutItem:completionHandler method
