MapView在8.0之後,用法有了一些新的用法(代理方法),在此之前需要導入
#import <MapKit/MapKit.h>
//創建位置服務對象
locationManager = [[CLLocationManager alloc] init];
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
//設置定位代理
locationManager.delegate = self;
//如果實在iOS8.0之後，我們需要添加以下操作
//1.調用方法--requestWhenInUseAuthorization 或者 requestAlwaysAuthorization
//2.
if ([UIDevice currentDevice].systemVersion.floatValue >= 8.0) {
[locationManager requestWhenInUseAuthorization];
}
//開始定位
[locationManager startUpdatingLocation];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark -CLLocationManagerDelegate
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
NSLog(@"定位成功");
//停止定位
[locationManager stopUpdatingLocation];
CLLocationCoordinate2D coordinate = newLocation.coordinate;
NSLog(@"位置：緯度：%.2f----經度：%.2f", coordinate.latitude, coordinate.longitude);
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateLocations:(NSArray *)locations
{
NSLog(@"新方法定位成功");
//停止定位
[locationManager stopUpdatingLocation];
CLLocation *location = [locations lastObject];
CLLocationCoordinate2D coordinate = location.coordinate;
NSLog(@"位置：緯度：%.2f----經度：%.2f", coordinate.latitude, coordinate.longitude);
//在iOS5.0之前使用位置反編碼
MKReverseGeocoder *mkReverse = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate];
mkReverse.delegate = self;
//開始反編碼
[mkReverse start];
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:location
completionHandler:^(NSArray *placemarks, NSError *error) {
NSLog(@"---------CLGeocoder---------------");
for (CLPlacemark *place in placemarks) {
