【iOS笔记 #7】iOS远程推送流程

iOS笔记系列目录

一 iOS消息推送流程

• 1.由App向iOS设备发送一个注册通知，用户需要同意系统发送推送
• 2.iOS应用向APNS远程推送服务器发送App的Bundle Id和Device UUID
• 3.APNS根据设备的UUID和App的Bundle Id生成deviceToken再发回App
• 4.App再将deviceToken发送给远程推送服务器（自己的服务器），再由服务器保存到数据库中
• 5.当自己的服务器想发送推送时，在远程推送服务器中输入想发送的消息并选择发给哪些用户的deviceToken，由远程推送服务器发送给APNS
• 6.APNS根据deviceToken发送给对应的用户

二 相关代码

1.获取DeviceToken

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // do some initiale working
    ...
    
    [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];
    return YES;
}

1).处理成功回调

- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSLog(@"Receive DeviceToken: %@", deviceToken);
    // 上传自家服务器
}

2).处理失败回调

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"注册失败，无法获取设备ID, 具体错误: %@", error);
}

2.处理接收消息回调

1)、App未启动

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if (launchOptions) {
        // do something else
        ...
    
    }
    
    [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound];

    return YES;
}

2)、App正在运行

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    if (application.applicationState == UIApplicationStateActive) {
        // App在前台
        // 转换成一个本地通知，显示到通知栏，你也可以直接显示出一个alertView，只是那样稍显aggressive：）
        UILocalNotification *localNotification = [[UILocalNotification alloc] init];
        localNotification.userInfo = userInfo;
        localNotification.soundName = UILocalNotificationDefaultSoundName;
        localNotification.alertBody = [userInfo objectForKey:@"alertInfo"];
        localNotification.fireDate = [userInfo objectForKey:@"date"];
        [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
    } else {
        // 后台到前台
    }
}

3.处理小红点

- (void)applicationDidEnterBackground:(UIApplication *)application {
    //设置应用程序图片右上角的数字(如果想要取消右上角的数字, 直接把这个参数值为0) 
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
