xCode推送通知。数组的大小具有非整数类型

Question

我遇到推送通知问题。在我的App代表中，我有：

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



UIApplicationState state = [application applicationState];
if (state == UIApplicationStateActive)
{
    NSString *cancelTitle = @"Close";
    NSString *showTitle = @"Show";
    NSString *message = [[userInfo objectForKey:@"aps"] objectForKey:@"alert"];


    UIAlertView *alertView [[[UIAlertView alloc] initWithTitle:@"Alert"
                                                       message:message
                                                      delegate:self
                                            cancelButtonTitle:cancelTitle
                                            otherButtonTitles:showTitle, nil] ];


    [alertView show];
}

我从服务器发送的json代码是：

// Create the payload body
$body['aps'] = array(
'badge' => 1,
'alert' => $message,
'sound' => 'sms-received1.caf '


);

任何人都可以看到我收到此错误的原因：数组大小为非整数类型（UIAvertView）

非常感谢任何帮助。

干杯，
