macos – Mac CoreLocation Services不要求权限

概述我正在编写一个需要使用CoreLocation服务的Mac App.只要我在安全首选项窗格中手动验证服务,代码和位置就可以正常工作.但是,框架不会自动d出权限对话框.文件说明： Important The user has the option of denying an application’s access to the location service data. During its i 我正在编写一个需要使用CoreLocation服务的Mac App.只要我在安全首选项窗格中手动验证服务,代码和位置就可以正常工作.但是,框架不会自动d出权限对话框.文件说明：

important The user has the option of denying an application’s access
to the location service data. During its initial uses by an
application,the Core Location framework prompts the user to confirm
that using the location service is acceptable. If the user denIEs the
request,the CLLocationManager object reports an appropriate error to
its delegate during future requests.

我确实得到了我的委托的错误,并且CLLocationManager上的locationServicesEnabled的值是正确的.缺少的唯一部分是向用户提示有关权限的提示.这发生在我的开发MPB和朋友MBP上.我们都不知道什么是错的.

有没有人碰到这个？

相关代码：

_locationManager = [CLLocationManager new];    [_locationManager setDelegate:self];[_locationManager setDesiredAccuracy:kCLLocationAccuracyKilometer];...[_locationManager startUpdatingLocation];

解决方法 我发现在Mac上,当你通过调用启动位置服务时

[locationManager startUpdatingLocation];

它会触发

- (voID)locationManager:(CLLocationManager *)manager dIDChangeAuthorizationStatus:(CLAuthorizationStatus)status

状态为

kCLAuthorizationStatusNotDetermined

如果您观察此状态,然后再次开始更新该位置,则会触发权限对话框：例如,

- (voID)locationManager:(CLLocationManager *)manager dIDChangeAuthorizationStatus:(CLAuthorizationStatus)status{    switch (status) {        case kCLAuthorizationStatusAuthorized:            NSLog(@"Location Services are Now Authorised");            [_locationManager startUpdatingLocation];            break;        case kCLAuthorizationStatusDenIEd:            NSLog(@"Location Services are Now DenIEd");            break;        case kCLAuthorizationStatusNotDetermined:            NSLog(@"Location Services are Now Not Determined");            //  We need to triger the OS to ask the user for permission.            [_locationManager startUpdatingLocation];            [_locationManager stopUpdatingLocation];            break;        case kCLAuthorizationStatusRestricted:            NSLog(@"Location Services are Now Restricted");            break;        default:            break;    }}
