ios - 关闭应用程序时如何从推送通知中获取数据？
<p><p>我想在应用关闭时从推送通知中获取数据。我正在使用下面给出的以下代码:</p>
<pre><code>- (void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
{
NSDictionary *aps = userInfo[@”aps”];
if (state == UIApplicationStateInactive){
// user tapped notification
NSLog(@"results%@",aps);
completionHandler(UIBackgroundFetchResultNewData);
} else {
// app is active
completionHandler(UIBackgroundFetchResultNoData);
}
}
</code></pre>
<p>在上面的代码中 NSLog(@"results%@",aps);应用程序在后台时不会打印值。请帮帮我</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>didReceiveRemoteNotification 仅在您点击通知时有效。所以它只会在您点击通知时为您提供数据，并且您的应用会打开。</p>
<p>如果要获取 NSDictionary *aps = userInfo[@”aps”];当您的应用程序处于终止状态时，您必须实现 pushkit 框架。</p>
