Answer 1

在 plist 中你必须添加 2 个条目

1. NSLocationWhenInUseUsageDescription
2. NSLocationAlwaysUsageDescription

将两者的字符串设为 "Location is required to find out where you are" 或任何内容

self.locationManager = [[CLLocationManager alloc]init];

if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
    [self.locationManager requestWhenInUseAuthorization];
}
self.locationManager.desiredAccuracy = kCLLocationAccuracyKilometer;
CLAuthorizationStatus authorizationStatus= [CLLocationManager authorizationStatus];

if (authorizationStatus == kCLAuthorizationStatusAuthorized ||
    authorizationStatus == kCLAuthorizationStatusAuthorizedAlways ||
    authorizationStatus == kCLAuthorizationStatusAuthorizedWhenInUse) {
    NSLog(@"You are authorized");

}

self.locationManager.delegate = self;
[self.locationManager startUpdatingLocation];
