[英]Location Services permission don't get saved iOS
我在Core Location Services中的本地化API有问题。 我收到请求位置服务权限的提示。 如果单击“允许”并转到“设置”,我可以看到我的应用没有权限。
这是我的GeoUtility类中的代码:
CLGeocoder *reverseGeocoder = [[CLGeocoder alloc] init];
CLLocationManager *lm = [[CLLocationManager alloc] init];
[lm setPurpose:@"Need to verify your region"];
[lm startUpdatingLocation];
由viewDidAppear中的viewController触发
我还在plist文件的“必需的设备功能”下添加了location-services
。
添加CoreLocation.framework和MapKit.framework
和
在.h中
#import <MapKit/MapKit.h>
CLLocationManager *locationManager;
CLGeocoder *geocoder;
鉴于确实加载
- (void)viewDidLoad
{
locationManager = [[CLLocationManager alloc] init];
geocoder = [[CLGeocoder alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
}
然后
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
CLLocation *currentLocation = newLocation;
if (currentLocation != nil) {
LongitudeLbl.text = [NSString stringWithFormat:@"%.8f",currentLocation.coordinate.longitude];
LatitudeLbl.text = [NSString stringWithFormat:@"%.8f",currentLocation.coordinate.latitude];
}
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
if (error == nil && [placemarks count] > 0) {
placemark = [placemarks lastObject];
NSString *addresstemp2 = [[NSString alloc] init];
NSString *subThoroughfare2 = [NSString stringWithFormat:@"%@",placemark.subThoroughfare];
NSString *thoroughfare2 = [NSString stringWithFormat:@"%@",placemark.thoroughfare];
NSString *postalCode2 = [NSString stringWithFormat:@"%@",placemark.postalCode];
NSString *locality2 = [NSString stringWithFormat:@"%@",placemark.locality];
NSString *administrativeArea2 = [NSString stringWithFormat:@"%@",placemark.administrativeArea];
NSString *country2 = [NSString stringWithFormat:@"%@",placemark.country];
if (![subThoroughfare2 isEqualToString:@"(null)"]) {
addresstemp2 = [NSString stringWithFormat:@"%@",subThoroughfare2];
}
if (![thoroughfare2 isEqualToString:@"(null)"]) {
addresstemp2 = [NSString stringWithFormat:@"%@ %@ \n",addresstemp2,thoroughfare2];
}
if (![postalCode2 isEqualToString:@"(null)"]) {
addresstemp2 = [NSString stringWithFormat:@"%@ %@",addresstemp2,postalCode2];
}
if (![locality2 isEqualToString:@"(null)"]) {
addresstemp2 = [NSString stringWithFormat:@"%@ %@ \n",addresstemp2,locality2];
}
if (![administrativeArea2 isEqualToString:@"(null)"]) {
addresstemp2 = [NSString stringWithFormat:@"%@ %@ \n",addresstemp2,administrativeArea2];
}
if (![country2 isEqualToString:@"(null)"]) {
addresstemp2 = [NSString stringWithFormat:@"%@ %@",addresstemp2,country2];
}
AddressLbl.text = [[NSString alloc] initWithString:addresstemp2];
[AddressLbl sizeToFit];
[locationManager stopUpdatingLocation];
} else {
}
} ];
}
您还可以在模拟器中更改设置,转到设置,然后选择定位服务,将其更改为开。 如果您的应用程序名称关闭,请查看它,然后更改为ON
