iOS10推送新增了UserNotifications Framework，使用起來其實很簡單。

只是在iOS10以上系統上點擊通知欄，回調方法不再走原來的這兩個方法

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {}- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {}
而是在前臺的時候回調
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPResentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
從后臺進入的時候回調
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
直接說怎么用吧：
1，導入頭文件
#import <UserNotifications/UserNotifications.h>
2，注冊通知
#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，回調方法中，獲取通知數據（前臺類似不做說明）
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler {    NSDictionary *userInfo = response.notification.request.content.userInfo; 　　//消息處理}
4，對于本地通知沒有什么變化依然會回調
-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification
