苹果的在iOS 10 中将通知相关的API统一成了UserNotifications.framework。在新的UserNotifications.framework中，苹果还增加了撤回单条通知，更新已展示同比，中途修改通知内容，在通知中展示图片、视频，自定义通知UI等一系列新功能。
iOS 10中使用远程推送
在Project -> Project Setting - > Capabilities, 打开 Push Notifications 开关。
注册通知
注册通知在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(nullable NSDictionary *)launchOptions NS_AVAILABLE_IOS(3_0); 方法里。
iOS 10使用- (void)requestAuthorizationWithOptions:(UNAuthorizationOptions)options completionHandler:(void (^)(BOOL granted, NSError *__nullable error))completionHandler; 方法来注册通知。
导入 #import <UserNotifications/UserNotifications.h>

上面的方法只在ios 10中有效， 所以要想兼容之前的版本，还是需要适配

注册结果的回调还是AppDelegate的代理方法。

响应通知
iOS 10 之前版本
在iOS 10之前的版本中，当应用是被通知打开的时候,可以通过 application:didFinishLaunchingWithOptions:方法的 launchOptions 参数所使用的 dictionary 访问到数据：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
. . .
if ([[UIDevice currentDevice].systemVersion floatValue] < 10.0) {
NSDictionary *notificationPayload = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
if (notificationPayload) {
NSLog(@"%@",notificationPayload);
}
}
return YES;
}
|
如果当通知到达的时候，你的应用已经在运行，通过 application:didReceiveRemoteNotification:fetchCompletionHandler: 方法的 userInfo 参数所使用 dictionary 访问到数据:
1

// Required for iOS 7+
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
//处理远程推送内容
NSLog(@"iOS7及以上系统，收到通知:%@", userInfo);
}

iOS10 以上需要使用下面代理方法来获得 userInfo ：

NSDictionary *userInfo = notification.request.content.userInfo;
if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
//TODO:处理远程推送内容
NSLog(@"%@", userInfo);
}
// 需要执行这个方法，选择是否提醒用户，有 Badge、Sound、Alert 三种类型可以选择设置
completionHandler(UNNotificationPresentationOptionAlert);
}
// 在后台和启动之前收到推送内容, 点击推送内容后，执行的方法
- (void)userNotificationCenter:(UNUserNotificationCenter *)center
didReceiveNotificationResponse:(UNNotificationResponse *)response
withCompletionHandler:(void (^)())completionHandler {
NSDictionary * userInfo = response.notification.request.content.userInfo;
if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {
//TODO:处理远程推送内容
