iOS：极光推送控制器跳转

Posted 2020-07-07 程序猿

在前面已经做完了极光消息的推送，那么有消息了，如何跳转到需要的控制器呢？其实，主要还是在userInfo这个消息里面做判断来处理，具体如下：

下面这两个是远程推送时接收消息的方法，这是应用程序提供的方法，只要成功注册了极光推送，推送消息时，就会调用这两个方法，在这两个方法收到的userInfo消息做判断即可。

// Required,For systems with less than or equal to ios6

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo；

 

 // IOS 7 Support Required

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler；

 

具体代码如下：我这里是区别环信推送消息控制器跳转和环信推送消息控制器跳转

通过在极光推送的服务器上设置自定义字段，用来判断跳转的是极光推送的消息控制器

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{

    // Required,For systems with less than or equal to iOS6
    [JPUSHService handleRemoteNotification:userInfo];
}

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler{

    // IOS 7 Support Required
    [JPUSHService handleRemoteNotification:userInfo];
    if (completionHandler) {
        completionHandler(UIBackgroundFetchResultNewData);
    }

    //消息提示数字
    self.badge = userInfo[@"aps"][@"badge"];
    //取得Extras字段内容
    NSString *customizeValue = [userInfo valueForKey:@"customizeExtras"]; //服务端中Extras字段，key是自己定义的,用来判断跳转的是极光推送的消息控制器
    
    // 启动程序,跳转到极光推送消息的控制器
    if ([customizeValue isEqualToString:@"Jpush"]) {
        KJTabViewController *rootVC = (KJTabViewController *)[UIApplication sharedApplication].keyWindow.rootViewController;
        rootVC.selectedIndex = 4;
        KJNavgationController *navc = rootVC.viewControllers[4];
        self.mineVC = navc.viewControllers[0];
        KJNewFriendController *newVC = [[KJNewFriendController alloc]init];
        [self.mineVC.navigationController pushViewController:newVC animated:YES];
        [self CancelBadgeValue];
        application.applicationIconBadgeNumber -= [self.badge integerValue];
    }
    else{ // 启动程序,跳转到环信推送消息的控制器
        KJTabViewController *rootVC = (KJTabViewController *)[UIApplication sharedApplication].keyWindow.rootViewController;
        rootVC.selectedIndex = 1;
    }
    
    
    // 应用正处理前台状态下，不会收到极光推送消息，因此在此处需要额外处理一下
    if (application.applicationState == UIApplicationStateActive) {
        UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle:@"您有一条推送消息"
                              message:userInfo[@"aps"][@"alert"]
                              delegate:self
                              cancelButtonTitle:@"取消"
                              otherButtonTitles:@"确定",nil];
        [alert show];
        
        //注册监听,取消badgeValue的数字
        [NotyCenter addObserver:self selector:@selector(CancelBadgeValue) name:@"CancelBadgeValueNotification" object:nil];
    }
