摘要：
iOS 8之后出现了一些新配置[self.managerrequestWhenUseAuthorization]；在信息中，将NSLocationWhenUseUsageDescriptionBOOLYENSLocationAlwaysUsageDescriptions字符串“Prompt Description”添加到plist文件中。记得添加依赖库CoreLocation.frameworkMapKit.fra
iOS8 之后出现一些新的配置
[self.manager requestWhenInUseAuthorization]; 并且在info.plist文件中增加 NSLocationWhenInUseUsageDescription BOOL YES NSLocationAlwaysUsageDescription string “提示描述”
记得加依赖库
CoreLocation.framework MapKit.framework
创建MapView
if (_mapView == nil) {
_mapView = [[MKMapView alloc]initWithFrame:CGRectMake(0, 0, 0.5, 0.5)];
// _mapView.userTrackingMode = MKUserTrackingModeFollow;
_mapView.delegate = self;
_mapView.showsUserLocation = YES;
[self.view addSubview:_mapView];
}
创建locationManager
if ([CLLocationManager locationServicesEnabled] == YES) {//判断定位是否可用
_locationManager = [[CLLocationManager alloc]init];
_locationManager.delegate = self;
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;//定位精确度
_locationManager.distanceFilter = 10; //位置变化10米更新位置信息
//NSLog(@"定位");
if([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
[_locationManager requestWhenInUseAuthorization];
}else{
//NSLog(@"定位不可用");
}
[_locationManager startUpdatingLocation];
CLLocationManager Delegate
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
//NSLog(@"%s",__FUNCTION__);
[manager stopUpdatingLocation];
NSLog(@"newLocation = %@",newLocation);
NSLog(@"oldLocation = %@",oldLocation);
//获取经度和纬度的结构体
CLLocationCoordinate2D coordinate = newLocation.coordinate;
//纬度信息，CLLocationDegrees类型实际上就是double型
CLLocationDegrees latitude = coordinate.latitude;
//经度信息，CLLocationDegrees类型实际上就是double型
CLLocationDegrees longitude = coordinate.longitude;
NSLog(@"%f,%f",latitude,longitude);
[self.latitude setText:[NSString stringWithFormat:@"纬度:%lf",latitude]];
[self.longitude setText:[NSString stringWithFormat:@"经度:%lf",longitude]];
/*
// 获取当前所在的城市名
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
//根据经纬度反向地理编译出地址信息
[geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *array, NSError *error)
{
if (array.count > 0)
{
CLPlacemark *placemark = [array objectAtIndex:0];
//详细信息
[self.address setText:[NSString stringWithFormat:@"地址:%@",placemark.name]];
//获取城市
NSString *city = placemark.locality;
if (!city) {
//四大直辖市的城市信息无法通过locality获得，只能通过获取省份的方法来获得（如果city为空，则可知为直辖市）
city = placemark.administrativeArea;
}
[self.city setText:[NSString stringWithFormat:@"城市:%@",city]];
}
else if (error == nil && [array count] == 0)
{
NSLog(@"No results were returned.");
}
else if (error != nil)
{
NSLog(@"An error occurred = %@", error);
}
}];
*/
}
-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{
NSLog(@"定位失败 ，%@",error);
}
MapView获得详细地址
- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation{
CLLocation * newLocation = userLocation.location;
self.lastCoordinate=mapView.userLocation.location.coordinate;
NSUserDefaults *standard = [NSUserDefaults standardUserDefaults];
[standard setObject:@(self.lastCoordinate.longitude) forKey:MMLastLongitude];
[standard setObject:@(self.lastCoordinate.latitude) forKey:MMLastLatitude];
CLGeocoder *clGeoCoder = [[CLGeocoder alloc] init];
CLGeocodeCompletionHandler handle = ^(NSArray *placemarks,NSError *error)
{
for (CLPlacemark * placeMark in placemarks)
{
NSDictionary *addressDic=placeMark.addressDictionary;
NSString *City=[addressDic objectForKey:@"City"];
// NSString *subLocality=[addressDic objectForKey:@"SubLocality"];
// NSString * adressName = [NSString stringWithFormat:@"%@%@",subLocality,street];
[self.city setText:[NSString stringWithFormat:@"城市:%@",City]];
[self.address setText:[NSString stringWithFormat:@"地址:%@",placeMark.name]];
[self stopLocation];
}
};
[[NSUserDefaults standardUserDefaults] synchronize];
[clGeoCoder reverseGeocodeLocation:newLocation completionHandler:handle];
}
停止定位
-(void)stopLocation
{
if (_mapView) {
NSLog(@"关闭");
_mapView.showsUserLocation = NO;
[_mapView removeFromSuperview];
_mapView = nil;
}
}
