iOS开发-远程推送

远程通知的原理

• 获取device Token的过程
  <div align = center>

  
  device Token
  

  </div>

• 从获得device Token到推送消息给设备的过程
  <div align = center>

  
  device Token
  

  </div>

• Provider 为消息发送的服务器端
• APNs 远程推送服务

配置证书

• 调试远程推送需要的证书文本

  • ios_development.cer 让电脑具备真机调试的能力
  • aps_development.cer 让电脑有调试APP推送服务的能力
  • iOS_Development.mobileprovision 某台电脑就能利用某台真机设备调试某个程序

• ios_development.cer配置略 CSR创建略

• 必需一个配置了精确的Bundld ID调试证书
  <div align = center>

  
  AppID
  

  </div>

• 创建完成之后,我们点击查看详情 Push Notifications是Enabled状态才可以
  <div align = center>
  

  edit
  </div>

• 为App ID创建APNs SSL证书(真机调试用的APNs SSL证书：要在哪台电脑上调试具有推送服务的App
  )
  <div align = center>

  
  edit
  

  </div>

• 生成描述文件 (描述文件的作用是用来描述:哪台设备要在哪台电脑上调试哪个程序)
  <div align = center>

  
  provisioning
  provisioning
  provisioning
  provisioning
  provisioning

</div>

• 最终会得到3个文件

  
  end
  

  先安装cer文件，再安装mobileprovision文件

远程通知实现流程

• 获取device Token
  要获取到正确的device Token,要确保下面选项是打开的(Xcode7之后)
  <div align = center>
  PUSH
  </div>

// AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    ///  注册通知
    ///  判断当前设备
    if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) {
        // iOS8 之后的版本
        //1. 配置通知的类型
        /*
         UIUserNotificationTypeBadge
         UIUserNotificationTypeSound
         UIUserNotificationTypeAlert
         */
        UIUserNotificationType type = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
        //2. 配置settings
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:type categories:nil];
        //3. 注册settings
        [application registerUserNotificationSettings:settings];
        
        //4. 注册远程通知
        [application registerForRemoteNotifications];
        
    } else {
        //1. 配置通知的类型
        /**
         UIRemoteNotificationTypeBadge
         UIRemoteNotificationTypeSound
         UIRemoteNotificationTypeAlert
         */
        UIRemoteNotificationType type = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert;
        //2. 注册远程通知
        [application registerForRemoteNotificationTypes:type];
        
    }
    return YES;
}
#pragma mark - 当完成注册远程通知时,会调用的方法,在这里返回deviceToken

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    
    //3c48ae8d f6e2c1ff 473c84ea edcfff3d 9dd3beee 30eefbcb e5158680 80da7238
    NSLog(@"%@",deviceToken);
    //deviceToken发送到自己的服务器做存储
}

• 消息处理

1.PushMeBaby

我们要借助PushMeBaby模拟服务器,来给我们的APP推送消息, PushMeBaby配置要做如下配置:
<div align = center>

pushMeBaby
</div>
2.代码实现

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //  注册通知
    ///  判断当前设备
    if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) {
        // iOS8 之后的版本
        //1. 配置通知的类型
        UIUserNotificationType type = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert;
        //2. 配置settings
        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:type categories:nil];
        //3. 注册settings
        [application registerUserNotificationSettings:settings];
        
        //4. 注册远程通知
        [application registerForRemoteNotifications];
        
    } else {
        //1. 配置通知的类型
        UIRemoteNotificationType type = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert;
        //2. 注册远程通知
        [application registerForRemoteNotificationTypes:type];
        
    }
    //程序退出的时候 我们可以在这里拿到远程通知的内容
    //launchOptions是一个字典
    if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) {
        NSDictionary *remoteKey = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey];
        NSLog(@"%@",remoteKey);
    }

    return YES;
}

#pragma mark - 当完成注册远程通知时,会调用的方法,在这里返回deviceToken
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    
    //3c48ae8d f6e2c1ff 473c84ea edcfff3d 9dd3beee 30eefbcb e5158680 80da7238
    NSLog(@"%@",deviceToken);
    //deviceToken发送到自己的服务器做存储
}

#pragma mark - 当接受到远程推送的值得时候回调用
// 此方法无论前台/后台/退出的情况下都会调用 iOS7 新增的
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler {
    
    // 逻辑处理
    NSLog(@"userInfo: %@",userInfo);
    // 必须调用的
    completionHandler(UIBackgroundFetchResultNewData);
}

3.控制台打印

2016-07-16 15:39:47.611 mall[8118:1494303] userInfo: {
    aps =     {
        alert = "\U4eca\U5929\U505a\U4e2a\U56db\U6709\U9752\U5e74.";
        badge = 1;
    };
}

4.真机效果
<div align = center>
