estimationUpdateIndex

当每个触摸对象的触摸特性发生变化时，该值将会单独增加

返回值是NSNumber

iOS9中添加的方法

PreciseLocationInView:

当前触摸对象的坐标

PrecisePreviousLocationInView:

UITouchProperties

UITouchPropertyForce

ShortcutItem

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

修改当前应用程序的某个shortcutItem

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

Peek and Pop

注册预览功能的代理对象和源视图

代理对象需要接受UIViewControllerPreviewingDelegate协议
