ios - 位置服务警告，即使它们已启用

Question

if (kCLAuthorizationStatusDenied) {
    UIAlertView *servicesDisabledAlert = [[UIAlertView alloc] initWithTitle:@"Location Services Disabled" message:@" Please go to settings  and enable them if you want to use all the features of this app  " delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [servicesDisabledAlert show];
}

即使启用了位置服务，也会弹出警报。

此代码放在 AppDelegate 的 application didFinishLaunchingWithOptions: 方法中。

Answer 1

你正在检查一个常量不为 nil，它永远为真

您需要查看当前的授权状态:

if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied)

编辑:RazorSharp 提出了一个很好的观点。驼峰式但以小写 k 开头的东西通常是常量
