iOS10推送新增了UserNotifications Framework，使用起来其实很简单。

只是在iOS10以上系统上点击通知栏，回调方法不再走原来的这两个方法

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {}- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {}
而是在前台的时候回调
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPResentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
从后台进入的时候回调
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
直接说怎么用吧：
1，导入头文件
#import <UserNotifications/UserNotifications.h>
2，注册通知
#define IOS8 ([[UIDevice currentDevice].systemVersion doubleValue] >= 8.0 && [[UIDevice currentDevice].systemVersion doubleValue] < 9.0)#define IOS8_10 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0 && [[UIDevice currentDevice].systemVersion doubleValue] < 10.0)#define IOS10 ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10.0)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中
if (IOS10) {        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];        center.delegate = self;        [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {            if (!error) {                NSLog(@"succeeded!");            }        }];    } else if (IOS8_10){//iOS8-iOS10        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIUserNotificationTypeSound) categories:nil];        [application registerUserNotificationSettings:settings];        [application registerForRemoteNotifications];    } else {//iOS8以下        [application registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];    }
 
3，回调方法中，获取通知数据（前台类似不做说明）
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {    NSDictionary *userInfo = response.notification.request.content.userInfo; 　　//消息处理}
4，对于本地通知没有什么变化依然会回调
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
