即使存在密钥，IOS 11+位置服务授权也会失败

Question

如何在安装了IOS 12并且目标版本设置为11的iPhone上使用定位服务来工作？ 我正在研究原型，因为我记得定位服务有点麻烦。 我有以下代码：

-(id) init {
if (self = [super init]) {
    manager = [[CLLocationManager alloc] init];
    [manager setDelegate:self];
    [manager setDesiredAccuracy:kCLLocationAccuracyNearestTenMeters];
    [manager setDistanceFilter:50];
    [manager requestWhenInUseAuthorization];
    switch ([CLLocationManager authorizationStatus]) {
        case kCLAuthorizationStatusNotDetermined:
            [self presentAlertForLocationServices];
            break;
        case kCLAuthorizationStatusRestricted:
            NSLog(@"Location restricted");
            break;
        case kCLAuthorizationStatusDenied:
            NSLog(@"Location Denied");
            break;
        case kCLAuthorizationStatusAuthorizedAlways:
            [manager startUpdatingLocation];
            NSLog(@"Updating locations...");
            break;
        case kCLAuthorizationStatusAuthorizedWhenInUse:
            [manager startUpdatingLocation];
            NSLog(@"Updating locations...");
            break;
    }
}
return self;

我有以下键：

<key>NSLocationWhenInUseUsageDescription</key>
<string>$(PRODUCT_NAME) always uses location </string>

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>$(PRODUCT_NAME) needs location in order to find nearby points of interest</string>

但是，运行该应用程序时出现以下错误： This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an “NSLocationWhenInUseUsageDescription” key with a string value explaining to the user how the app uses this data This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an “NSLocationWhenInUseUsageDescription” key with a string value explaining to the user how the app uses this data 。

我尝试了3种不同的键（NSLocationWhenInUseUsageDescription，NSLocationAlwaysAndWhenInUseUsageDescription，NSLocationAlwaysInUseUsageDescription）以及2种不同的授权请求，并以多种方式组合在一起而没有运气。 我正在使用XCode 10.0（10A255）。 任何指导将不胜感激。 我确实发现Apple存在密钥无法正常工作的问题，但是那是一年多以前的事了，我确定问题已经解决，尽管我不知道答案。

检查以确保您编辑了正确的Info.plist-应用程序真正使用的Info.plist。 是您在针对该应用目标的构建设置中指向的那个吗？
