IOS10 遠程推送適配

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

建議看看極光推送的Demo，裡面寫的更詳細。

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 {}

而是在前台的時候回調

- (void)userNotificationCenter:(UNUserNotificationCenter *)center 
willPresentNotification:(UNNotification *)notification 
withCompletionHandler:(void (^)
(UNNotificationPresentationOptions))completionHandler

從後台進入的時候回調

- (void)userNotificationCenter:(UNUserNotificationCenter *)center
 didReceiveNotificationResponse:(UNNotificationResponse *)response 
withCompletionHandler:(void (^)())completionHandler

直接說怎麼用吧：

1，導入頭文件

#ifdef NSFoundationVersionNumber_iOS_9_x_Max
#import <UserNotifications/UserNotifications.h>
#endif

2，注冊通知

- (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_9){//iOS8-iOS9
  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

- (void)userNotificationCenter:(UNUserNotificationCenter *)center 
didReceiveNotificationResponse:(UNNotificationResponse *)response 
withCompletionHandler:(void (^)())completionHandler {
 NSDictionary *userInfo = response.notification.request.content.userInfo;
 　　//消息處理
 if([request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
  //判斷為遠程推送
 }else {
  // 判斷為本地通知 
 }
}

4，對於本地通知沒有什麼變化依然會回調

-(void)application:(UIApplication *)application 
didReceiveLocalNotification:(UILocalNotification *)notification
