Objective-C 推送通知

系统 iOS 10.x
本文简单记录远程通知，更多细节看心情整理

---

1.注册通知

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    if (iOS系统大于10.0) {        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];        center.delegate = self;        [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) {            if (granted) {                NSLog(@"register success");            } else {                NSLog(@"register failure");            }        }];    } else {        UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert) categories:nil];        [[UIApplication sharedApplication] registerUserNotificationSettings:setting];    }    [[UIApplication sharedApplication] registerForRemoteNotifications];    return YES;}

2.处理token

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {    // 自定义处理token    NSLog(@"%@",deviceToken);}

3.接收远程通知

/** iOS3.0 ~ 10.0 前台状态下,当接收到远程通知 点击通知 完全退出情况下，点击通知，不会执行 */- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {    double version = [[[UIDevice currentDevice] systemVersion] doubleValue];    if (version < 10.0) {        NSLog(@"收到远程通知");        self.window.rootViewController.view.backgroundColor = [UIColor redColor];    }}/* iOS7.0 ~ 10.0 如果实现了该方法，则不执行application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 前台状态下,当接收到远程通知 点击通知 完全退出情况下，点击通知，也会执行 只要接收到了通知，不管当前APP的状态，不管后台，还是锁屏，都直接执行这个方法 要求： 1.必须勾选后台模式Remote Notification 2.告诉系统是否有新的内容更新（执行完成代码块） 3.设置发送通知的格式（"content-available":"xxx"） { "aps" : { "alert":"This is some fancy message.", "badge":1, "content-available":"xxx" } } 调用系统回调代码块的作用 1.系统会估量App消耗的电量，并根据传递的UIBackgroundFetchResult参数记录新数据是否可用 2.调用完成的处理代码时，应用的界面缩略图会自动更新 */- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {    double version = [[[UIDevice currentDevice] systemVersion] doubleValue];    if (version < 10.0) {        NSLog(@"收到远程通知-----2");        self.window.rootViewController.view.backgroundColor = [UIColor blueColor];    }    completionHandler(UIBackgroundFetchResultNewData);}/* 前台状态下 完全退出，点击通知，不会执行这个方法 */- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {    if([notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {        NSLog(@"收到远程通知-----3.remote");        self.window.rootViewController.view.backgroundColor = [UIColor yellowColor];    }    else {        NSLog(@"收到本地通知-----3.local");        self.window.rootViewController.view.backgroundColor = [UIColor orangeColor];    }    // UNNotificationPresentationOptionAlert 在前台状态下会出现通知栏    completionHandler(UNNotificationPresentationOptionSound | UNNotificationPresentationOptionBadge | UNNotificationPresentationOptionAlert);}/* 点击通知 完全退出，点击通知，也会执行这个方法 */- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler {    if([response.notification.request.trigger isKindOfClass:[UNPushNotificationTrigger class]]) {        NSLog(@"收到远程通知-----4.remote");        self.window.rootViewController.view.backgroundColor = [UIColor purpleColor];    }    else {        NSLog(@"收到本地通知-----4.local");        self.window.rootViewController.view.backgroundColor = [UIColor greenColor];    }    completionHandler();}
