提取＆QUOT;警报＆QUOT;从推送通知文本 [英] Extract "alert" text from push notification

问题描述

我有以下的code放置在我的应用程序委托文件。从理论上讲，它应该提取的推送通知的消息，并在 UIAlertView中显示它 - 但它显示的标题和蜡烛按钮，而不是其他。任何人都可以看到我错了？

   - （无效）应用：（*的UIApplication）的应用didReceiveRemoteNotification：（NSDictionary的*）{用户信息
    [PFPush handlePush：用户信息];
    pushText = [USERINFO objectForKey：@警报];
    UIAlertView中*警报= [[UIAlertView中页头]
                          initWithTitle：NSLocalizedString（@新闻，）
                          消息：pushText
                          代表：无
                          cancelButtonTitle：@确定
                          otherButtonTitles：无];
    [警报显示]
}
 

解决方案

推载荷的结构如下：

  {
    APS：{
             警告：推送通知文本
             }
}
 

所以，你需要拉出APS字典冷杉，然后你可以检索警戒键的值：

  pushText = [[USERINFO objectForKey：@APS] objectForKey：@警报];
 

I have the following code placed in my app delegate file. In theory, it should be extracting the message from the push notification and displaying it in a UIAlertview - yet it displays the title and the candle button, and nothing else. Can anybody see where I am going wrong?

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    [PFPush handlePush:userInfo];
    pushText = [userInfo objectForKey:@"alert"];
    UIAlertView *alert = [[UIAlertView alloc]
                          initWithTitle:NSLocalizedString(@"News", "")
                          message:pushText
                          delegate:nil
                          cancelButtonTitle:@"Ok"
                          otherButtonTitles: nil];
    [alert show];
}

解决方案

The push payload has the following structure:

{
    "aps" : {
             "alert" : "Push notification text"
             }
}

So you need to pull out the "aps" dictionary firs and then you can retrieve the value for the "alert" key:

 pushText = [[userInfo objectForKey:@"aps"] objectForKey:@"alert"];
