iOS10推送通知适配

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
