在任何人感到不安之前,我已阅读了许多Apple Dev论坛帖子和堆栈溢出帖子,无法弄清楚为什么我的应用程序拒绝提示用户允许使用时授权.

我已将以下密钥添加到我的Info.plist文件中,并附带一个String值：

NSLocationWhenInUseUsageDescription

然后我写了(在Swift和Obj-C中)应该提示用户的代码：

@property CLLocationManager *location;
...
@synthesize location;
...
location = [[CLLocationManager alloc] init];
location.delegate = self;

location.desiredAccuracy = kCLLocationAccuracyBest;
location.distanceFilter = kCLDistanceFilterNone;

[location requestWhenInUseAuthorization];
[location startUpdatingLocation];


I'm using the following CLLocationManagerDelegate methods.
- (void) locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
- (void) locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status

这基本上是直接从Apple“LocateMe”示例代码中复制的.

无论我尝试什么样的各种序列或细微的变化,应用程序都不会提示允许授权.我已经使用switch语句来确定[CLLocationManager authorizationStatus]的状态,但是不断收到“未确定”的响应.

if ([CLLocationManager locationServicesEnabled]) {
        switch ([CLLocationManager authorizationStatus]) {
            case kCLAuthorizationStatusAuthorizedAlways:
                NSLog(@"Always Authorized");
                break;
            case kCLAuthorizationStatusDenied:
                NSLog(@"Denied");
                break;
            case kCLAuthorizationStatusAuthorizedWhenInUse:
                NSLog(@"Authorized in Use");
                break;
            case kCLAuthorizationStatusNotDetermined:
                NSLog(@"Not Determined");
                break;
            case kCLAuthorizationStatusRestricted:
                NSLog(@"Restricted");
                break;
        }

    }

任何帮助将不胜感激.我正在运行带有iOS 8.1.2物理设备的Xcode 6.2(6C101)和用于测试的iOS 8.2(12D5452a)模拟器.
