如何在iOS中使用CLLocationManager获取当前位置 [英] How to get current location using CLLocationManager in iOS
本文介绍了如何在iOS中使用CLLocationManager获取当前位置的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我已经可以使用纬度和经度找到当前位置,但我也希望能够找到给定邮政编码的当前位置。
I can already find the current location using latitude and longitude, but I would also like to be able to find the current location given a zip code.
这是到目前为止我所拥有的:
Here is what I have so far:
.h
#import <MapKit/MapKit.h>
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
@interface ViewController : UIViewController<CLLocationManagerDelegate>
{
CLLocationManager *locationManager;
CLLocation *currentLocation;
IBOutlet UILabel *label1;
IBOutlet UILabel *lable2;
}
@property (weak, nonatomic) IBOutlet MKMapView *myMapview;
@property (weak, nonatomic) IBOutlet UILabel *label2;
@property (weak, nonatomic) IBOutlet UILabel *lable1;
@end
.m
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
locationManager = [[CLLocationManager alloc]init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
_myMapview.showsUserLocation = YES;
[self->locationManager startUpdatingLocation];
CLLocation *location = [locationManager location];
CLLocationCoordinate2D coordinate = [location coordinate];
NSString *latitude = [NSString stringWithFormat:@"%f", coordinate.latitude];
NSString *longitude = [NSString stringWithFormat:@"%f", coordinate.longitude];
//NSLog(@"dLatitude : %@", latitude);
//NSLog(@"dLongitude : %@",longitude);
NSLog(@"MY HOME :%@", latitude);
NSLog(@"MY HOME: %@ ", longitude);
}
#pragma mark CLLocationManager Delegate
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
currentLocation = [locations objectAtIndex:0];
[locationManager stopUpdatingLocation];
[self->locationManager stopUpdatingLocation];
NSLog(@"my latitude :%f",currentLocation.coordinate.latitude);
NSLog(@"my longitude :%f",currentLocation.coordinate.longitude);
label1.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
lable2.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
NSLog(@"Detected Location : %f, %f", currentLocation.coordinate.latitude, currentLocation.coordinate.longitude);
CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
[geocoder reverseGeocodeLocation:currentLocation
completionHandler:^(NSArray *placemarks, NSError *error)
{
if (error)
{
NSLog(@"Geocode failed with error: %@", error);
return;
}
NSLog(@"Monday");
CLPlacemark *placemark = [placemarks objectAtIndex:0];
NSLog(@"placemark.ISOcountryCode %@",placemark.ISOcountryCode);
}];
}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
NSLog(@"didUpdateToLocation: %@", newLocation);
CLLocation *currentLocation = newLocation;
if (currentLocation != nil)
{
label1.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];
lable2.text = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];
}
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
推荐答案
步骤1:在 .h
文件中导入 MobileCoreServices
框架
#import< MobileCoreServices / MobileCoreServices.h>
第2步:添加委托 CLLocationManagerDelegate
@interface yourViewController : UIViewController<CLLocationManagerDelegate>
{
CLLocationManager *locationManager;
CLLocation *currentLocation;
}
第3步:在类文件中添加此代码
Step 3: Add this code in class file
- (void)viewDidLoad
{
[super viewDidLoad];
[self CurrentLocationIdentifier]; // call this method
}
步骤4:方法获取位置
//------------ Current Location Address-----
-(void)CurrentLocationIdentifier
{
//---- For getting current gps location
locationManager = [CLLocationManager new];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];
//------
}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
currentLocation = [locations objectAtIndex:0];
[locationManager stopUpdatingLocation];
CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error)
{
if (!(error))
{
CLPlacemark *placemark = [placemarks objectAtIndex:0];
NSLog(@"\nCurrent Location Detected\n");
NSLog(@"placemark %@",placemark);
NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
NSString *Address = [[NSString alloc]initWithString:locatedAt];
NSString *Area = [[NSString alloc]initWithString:placemark.locality];
NSString *Country = [[NSString alloc]initWithString:placemark.country];
NSString *CountryArea = [NSString stringWithFormat:@"%@, %@", Area,Country];
NSLog(@"%@",CountryArea);
}
else
{
NSLog(@"Geocode failed with error %@", error);
NSLog(@"\nCurrent Location Not Detected\n");
//return;
CountryArea = NULL;
}
/*---- For more results
placemark.region);
placemark.country);
placemark.locality);
placemark.name);
placemark.ocean);
placemark.postalCode);
placemark.subLocality);
placemark.location);
------*/
}];
}
