iOS 总结下本地推送和远程推送所走的方法

一、注册苹果APNS远程推送

在didFinishLaunchingWithOptions:中调用此方法

/**
 注册苹果推送，获取deviceToken用于推送
 
 @param application   application
 @param launchOptions application启动参数
 */
- (void)registerAPNS:(UIApplication *)application launchOptions:(NSDictionary *)launchOptions
{
    CGFloat systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (systemVersion >= 10.0) {
        UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
        center.delegate = self;
        [center requestAuthorizationWithOptions:UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound completionHandler:^(BOOL granted, NSError * _Nullable error) {
            if (granted) {
                // granted
                NSLog(@"User authored notification.");
                [application registerForRemoteNotifications];
            } else {
                // not granted
                NSLog(@"User denied notification.");
            }
        }];
    }else if (systemVersion >= 8.0) {
        // iOS >= 8 Notifications
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil];
        [application registerUserNotificationSettings:settings];
        [application registerForRemoteNotifications];
    }else {
        // iOS < 8 Notifications
        UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:myTypes];
    }
}

注册完成回调方法

/*
 *  苹果推送注册成功回调，将苹果返回的deviceToken上传到服务器
 */
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken;

/*
 *  苹果推送注册失败回调
 */
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error;

二、发送本地推送的方法：

    UILocalNotification *localNotification = [[UILocalNotification alloc] init];
    localNotification.alertTitle = @"NotificationTitle";//推送显示的标题
    localNotification.fireDate = [NSDate date];//设置推送时间
    localNotification.timeZone = [NSTimeZone defaultTimeZone];//设置时区
    localNotification.repeatInterval = NSCalendarUnitDay;//设置重复的间隔
    localNotification.soundName = UILocalNotificationDefaultSoundName;//推送声音
    localNotification.alertBody = @"NotificationContent";//推送内容
    localNotification.applicationIconBadgeNumber = 1; //显示在icon上的红色圈中的数子
    localNotification.userInfo = @{@"content":localNotification.alertBody};//userInfo中的信息

    [[UIApplication sharedApplication] presentLocalNotificationNow:localNotification]; //立即发起本地推送

//    UIUserNotificationSettings *localNotificationSettings = [UIUserNotificationSettings settingsForTypes:1 << 2 categories:nil];
//    [[UIApplication sharedApplication] registerUserNotificationSettings:localNotificationSettings];
//    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

三、收到本地推送通知和远程推送通知及点击通知所走的方法

根据系统版本分为以下几个方法，获取到userInfo之后即可处理相关信息。

1.Version < iOS10.0

• App已经杀死，点击远程和本地推送的消息时调用：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
   NSLog(@"userInfo: %@,",[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]);
}

• App处于前台收到远程推送消息，或者后台（未杀死）点击远程推送消息时调用

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo {
 NSLog(@"userInfo : %@",userInfo);
    if (application.applicationState == UIApplicationStateActive) {
        //app在前台
    }else{
        //app在后台点击远程推送
    }
}

• App处于前台收到本地推送消息，或者后台（未杀死）点击本地推送消息时调用

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
 NSLog(@"userInfo : %@",notification.userInfo);
    if (application.applicationState == UIApplicationStateActive) {
        //app在前台
    }else{
        //app在后台点击远程推送
    }
}

2.Version >= iOS10.0

• App已经杀死，点击远程和本地推送的消息时调用：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
   NSLog(@"userInfo: %@,",[launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]);
}

UNUserNotificationCenterDelegate 的代理方法

• App处于前台收到本地推送或者远程推送时调用

- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler __IOS_AVAILABLE(10.0) __TVOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0){
  NSLog(@"userInfo : %@",notification.request.content.userInfo);
}

• App处于后台（未杀死）点击本地推送或者远程推送时调用

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler __IOS_AVAILABLE(10.0) __WATCHOS_AVAILABLE(3.0) __TVOS_PROHIBITED{
  NSLog(@"userInfo : %@",notification.request.content.userInfo);
}

PS:应该就这些了吧，如有错误请留言撒~
