ios - 检查是否启用推送或启用位置 ios sdk

Question

我正在使用以下代码来检测这两个(推送通知和定位服务)

    [postvars setObject:([CLLocationManager locationServicesEnabled])?@"true":@"false" forKey:@"locationServicesEnabled"];

    BOOL pushEnabled = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
    [postvars setObject:(pushEnabled)?@"true":@"false" forKey:@"pushServicesEnabled"];

但问题是，即使我在应用程序中出现提示时点击不允许，我也总是对两者都成立。同样在设置应用程序中，我检查了位置设置为从不，通知副标题显示。这段代码有什么问题？谁能在这方面指导我。

仅仅检查 [CLLocationManager locationServicesEnabled] 是不够的。

if([CLLocationManager locationServicesEnabled] && 
   [CLLocationManager authorizationStatus] != kCLAuthorizationStatusDenied)
{
    [postvars setObject:@"true" forKey:@"locationServicesEnabled"];

}

通知检查这个很棒的SO answer

BOOL pushEnabled = [[UIApplication sharedApplication] isRegisteredForRemoteNotifications];
[postvars setObject:(pushEnabled)?@"true":@"false" forKey:@"pushServicesEnabled"];

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types == UIRemoteNotificationTypeNone) 
   {
    [postvars setObject:@"false" forKey:@"pushServicesEnabled"];
}
