常用方法：
创建一个UIApplicationShortcutItem：
- (instancetype)initWithType:(NSString *)type localizedTitle:(NSString *)localizedTitle localizedSubtitle:(nullable NSString *)localizedSubtitle icon:(nullable UIApplicationShortcutIcon *)icon userInfo:(nullable NSDictionary<NSString *, id <NSSecureCoding>> *)userInfo NS_DESIGNATED_INITIALIZER;
- (instancetype)initWithType:(NSString *)type localizedTitle:(NSString *)localizedTitle;
其中：
- type代表：必传，app定义的主屏幕快速操作类型，可以用于确定某元素点击。
- localizedTitle：展示的title
- localizedSubtitle：sub title
- icon：该item左侧或者右侧的icon，类型为UIApplicationShortcutIcon
- userInfo:用户自定义的一些信息
1.3.2.UIApplicationShortcutIcon
icon有两种获取方式：一种是使用系统自带的类型，一种是用户自定义（根据图片名）。
1.3.2.1 系统自带类型
// Create an icon using a system-defined image.
+ (instancetype)iconWithType:(UIApplicationShortcutIconType)type;
系统自带类型包括以下几种：
1.3.2.1 用户自定义
// Create an icon from a custom image.
// The provided image named will be loaded from the app's bundle
// and will be masked to conform to the system-defined icon style.
+ (instancetype)iconWithTemplateImageName:(NSString *)templateImageName;
