ios - 推送通知 applicationIconBadgeNumber 在 ios7 中未更新
<p><p>我在应用程序委托(delegate)中使用以下代码接收远程通知，但其 applicationIconBadgeNumber(以红色/白色显示在应用程序图标的左上角)在后台应用程序时未更新。当收到推送通知时，它会以幻灯片动画出现在屏幕的上角，在通知有效负载中，角标(Badge)计数正在完美地从服务器端发出。</p>
<p>在 <code>didFinishLaunchingWithOptions</code> 我放了以下代码</p>
<pre><code>;
</code></pre>
<p>远程通知代表:</p>
<pre><code>- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSString *deviceTokenTrimmed = [[[
stringByReplacingOccurrencesOfString:@"<"withString:@""]
stringByReplacingOccurrencesOfString:@">" withString:@""]
stringByReplacingOccurrencesOfString: @" " withString: @""];
currentdeviceToken=deviceTokenTrimmed;
[ setValue:deviceTokenTrimmed forKey:@"pushtoken"];
NSLog(@"Device Token didRegisterForRemoteNotificationsWithDeviceToken :%@",deviceTokenTrimmed);
}
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
NSLog(@"Device Token in FailToRegister RemoteNotifications ERROR %@",error);
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
NSLog(@"%@",userInfo);
if (application.applicationState == UIApplicationStateActive)
{
/***********code to show alert********/
if (![[initWithString:[ objectForKey: @"alert"]] isEqualToString:@""] && [initWithString:[ objectForKey: @"alert"]]!=nil) {
NSString *MSG =[initWithString:[ objectForKey: @"alert"]];
UIAlertView *alert = [initWithTitle:@"Message" message:MSG delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil];
;
}else{
UIAlertView *alert = [initWithTitle:@"Message" message:@"Notification Received." delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil, nil];
;
}
}else{
application.applicationIconBadgeNumber =[[ objectForKey: @"badge"]integerValue];
}
}
</code></pre>
<p>提前致谢。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我找到了 sol，实际上 application:didReceiveRemoteNotification 应用程序在后台时没有调用，它的 os 负责在应用程序在后台时更新 applicationIconBadgeNumber，
就我而言，实际问题出在有效载荷中。从服务器端它被设置为字符串，但它应该是整数。我正在发布用 php 编写的有效载荷正确代码。</p>
<pre><code>// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'sound.caf',
'badge' => $badge_count // Should be int type
);
</code></pre>
