iOS 远程推送 总结

    相关配置完成后，我们就来实现相应的远程推送功能。

    一、向APNS服务器注册

大致流程：

1. 一般在

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    [self registerForRemoteNotificationWithOptions:launchOptions];
    return YES;
}

中注册远程推送

- (void)registerForRemoteNotificationWithOptions:(NSDictionary *)launchOptions {
    // apn 内容获取：
    // 一般启动 lauchOptions 为 nil
    // 远程启动 lauchOptions 有值
    /**
     如果launchOptions包含UIApplicationLaunchOptionsRemoteNotificationKey表示用户点击apn 通知导致app被启动运行；
     如果不含有对应键值则表示 App 不是因点击apn而被启动，可能为直接点击icon被启动或其他。
     */
    //   NSDictionary *remoteNotification = [launchOptions objectForKey: UIApplicationLaunchOptionsRemoteNotificationKey];
    
    /**
     //系统原生的注册方法
     if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0){
     UIUserNotificationType type = UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;
     UIUserNotificationSettings *setting = [UIUserNotificationSettings settingsForTypes:type categories:nil];
     [application registerUserNotificationSettings:setting];
     }else{
     UIRemoteNotificationType *type = UIRemoteNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;
     [application registerForRemoteNotificationTypes:type];
     }
     */
    
    //Required
    /**
     JPush 注册方法
     */
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
        /**
         远程推送侧滑所显示的button “OK”，“回复“，
         根据远程推送接收到的数据（JSON）中key ： ”category“
         来判断用哪个 action
         */
        NSMutableSet *categories = [NSMutableSet set];
        
        UIMutableUserNotificationCategory *category = [[UIMutableUserNotificationCategory alloc] init];
        category.identifier = @"identifier";
        
        UIMutableUserNotificationAction *action = [[UIMutableUserNotificationAction alloc] init];
        action.identifier = @"test2";
        action.title = @"OK";
        action.activationMode = UIUserNotificationActivationModeBackground;
        action.authenticationRequired = YES;
        action.destructive = NO;//YES显示为红色，NO显示为蓝色
        
        NSArray *actions = @[ action ];
        [category setActions:actions forContext:UIUserNotificationActionContextMinimal];
        [categories addObject:category];
        
        //可以添加自定义categories
        [JPUSHService registerForRemoteNotificationTypes:(UIUserNotificationTypeBadge |
                                                          UIUserNotificationTypeSound |
                                                          UIUserNotificationTypeAlert)
                                              categories:categories];<p class="p1"><span class="s1">//categories </span><span class="s2">可以传</span><span class="s1"> nil</span></p>
    } else {
        //categories 必须为nil
        [JPUSHService registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |
                                                          UIRemoteNotificationTypeSound |
                                                          UIRemoteNotificationTypeAlert)
                                              categories:nil];
    }
    //Required
    // 如需继续使用pushConfig.plist文件声明appKey等配置内容，请依旧使用[JPUSHService setupWithOption:launchOptions]方式初始化。
    [JPUSHService setupWithOption:launchOptions appKey:@"c3cecb70fdd6461eb0746347"
                          channel:@"Publish channel"
                 apsForProduction:false
            advertisingIdentifier:nil];
}

UIMutableUserNotificationAction 点击回调函数

// Called when your app has been activated by the user selecting an action from
// a remote notification.
// A nil action identifier indicates the default action.
// You should call the completion handler as soon as you've finished handling
// the action.
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo
  completionHandler:(void (^)())completionHandler {
}

服务端设置

服务端payload格式:aps增加category字段，当该字段与客户端UIMutableUserNotificationCategory的identifier匹配时，触发设定的action和button显示。

//payload example:
{
	"aps":{
		"alert":"example", 
		"sound":"default", 
		"badge": 1, 
		"category":"identifier"
	}
}

2. APNS 服务器放回DeviceToken，如果注册成功，上传deviceToken到自己的服务器（或者第三方服务器，如JPush）。

 2.1注册成功

// 向APNS 注册成功后放回deviceToken
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken{
    
    NSString *string = [[[[deviceToken description] stringByReplacingOccurrencesOfString:@"<" withString:@""] stringByReplacingOccurrencesOfString:@">" withString:@""] stringByReplacingOccurrencesOfString:@" " withString:@""];
    NSLog(@"deviceTokenString : %@ " , string);
    /// Required - 注册 DeviceToken
    [JPUSHService registerDeviceToken:deviceToken];
}

 2.1 注册失败

// 注册远程推送失败
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    //Optional
    NSLog(@"did Fail To Register For Remote Notifications With Error: %@", error);
}

 二、接收/处理 远程推送

// 基于iOS 6 及以下的系统版本，如果 App状态为正在前台或者点击通知栏的通知消息
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
    
    // Required,For systems with less than or equal to iOS6
    [JPUSHService handleRemoteNotification:userInfo];
}

/**
 *  iOS7之后，接收到推送消息的代理方法
 *  接收到推送通知后，需要判断当前程序所处的状态，并根据APP的业务做出相应的处理
 *  在处理完后，需要调用completionHandler block 回调
 */
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(nonnull void (^)(UIBackgroundFetchResult))completionHandler{
    
    NSLog(@"%@", NSLocalizedString(@"TestA", nil));
    NSLog(@"this is iOS7 Remote Notification");
    
    
    if (application.applicationState == UIApplicationStateInactive){
        //程序处于非活跃状态，手机锁屏，双击home键等
        NSLog(@"inactive");
        
    }else if (application.applicationState == UIApplicationStateBackground){
        //应用程序处于后台，例如，点击home键进入后台等
        NSLog(@"background");
        
    }else if (application.applicationState == UIApplicationStateActive){
        //应用程序活跃状态，应用程序在前台运行时
        NSLog(@"action");
    }
    
    // IOS 7 Support Required
    [JPUSHService handleRemoteNotification:userInfo];
    completionHandler(UIBackgroundFetchResultNewData);
    //    执行completionHandler有两个目的
    //
    //    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
    //
    //    注意：接收到远程通知到执行完网络请求之间的时间不能超过30秒
    
    
}
