iOS10 废弃了一些API，包括：
CloudKit的CKDiscoverAllContactsOperation, CKDiscoveredUserInfo, CKDiscoverUserInfosOperation, CKFetchRecordChangesOperation类。这些类被 CKDiscoverAllUserIdentitiesOperation,CKUserIdentity,CKDiscoverUserIdentitiesOperation, and CKFetchRecordZoneChangesOperation类替代，后面这些类都支持记录共享。CKSubscription 的一些API，例如关于区域订阅的变量和方法被 CKRecordZoneSubscription 类的相关API 替代，关于查询订阅的变量和方法被CKQuerySubscription类的相关API替代。
几个与处处可见的内容相关的NSPersistentStoreCoordinator 标记
ADBannerView类和ADInterstitialAd类以及这两个类在 UIViewController里的相关内容
一些与浮点类型变量相关的SKUniform里的内容。使用像initWithName:vectorFloat2: 和uniformWithName:matrixFloat2x2:等合适的方法替代。
一些与通知相关的UIKit类，例如 UILocalNotification,UIMutableUserNotificationAction,UIMutableUserNotificationCategory,UIUserNotificationAction, UIUserNotificationCategory, UIUserNotificationSettings等。用User Notifications framework里的相关API来代替。
handleActionWithIdentifier:forLocalNotification:,handleActionWithIdentifier:forRemoteNotification:, didReceiveLocalNotification:withCompletion:,didReceiveRemoteNotification:withCompletion: 等这些WatchKit方法。用handleActionWithIdentifier:forNotification: 和didReceiveNotification:withCompletion:来替代。
