我已经可以使用纬度和经度查找当前位置，但我还希望能够找到给定邮政编码的当前位置。
这是我到目前为止所做的：

#import <MapKit/MapKit.h>
#import <UIKit/UIKit.h>
#import <CoreLocation/CoreLocation.h>
@interface ViewController : UIViewController<CLLocationManagerDelegate>

第1步：在MobileCoreServices文件中导入.h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：在课程文件中添加此代码
- (void)viewDidLoad
{
[super viewDidLoad];
[self CurrentLocationIdentifier]; // call this method
}
第4步：获取位置的方法
//------------ 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);
------*/
}];
}

以下是使用块
获取用户当前位置的代码 1）#import <CoreLocation/CoreLocation.h>
2）<CLLocationManagerDelegate>
3）在.h文件中
//Location
typedef void(^locationBlock)();
//Location
-(void)GetCurrentLocation_WithBlock:(void(^)())block;
@property (nonatomic, strong) locationBlock _locationBlock;
@property (nonatomic,copy)CLLocationManager *locationManager;
@property (nonatomic)CLLocationCoordinate2D coordinate;
@property (nonatomic,strong) NSString *current_Lat;
@property (nonatomic,strong) NSString *current_Long;
4）在.m文件中
#pragma mark - CLLocationManager
-(void)GetCurrentLocation_WithBlock:(void(^)())block {
self._locationBlock = block;
_locationManager = [[CLLocationManager alloc] init];
[_locationManager setDelegate:self];
[_locationManager setDistanceFilter:kCLDistanceFilterNone];
[_locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
if (IS_OS_8_OR_LATER) {
if ([_locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]) {
[_locationManager requestWhenInUseAuthorization];
[_locationManager requestAlwaysAuthorization];
}
}
[_locationManager startUpdatingLocation];
}
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
CLLocation *currentLoc=[locations objectAtIndex:0];
_coordinate=currentLoc.coordinate;
_current_Lat = [NSString stringWithFormat:@"%f",currentLoc.coordinate.latitude];
_current_Long = [NSString stringWithFormat:@"%f",currentLoc.coordinate.longitude];
NSLog(@"here lat %@ and here long %@",_current_Lat,_current_Long);
self._locationBlock();
[_locationManager stopUpdatingLocation];
_locationManager = nil;
}
- (void)locationManager:(CLLocationManager *)manager
didFailWithError:(NSError *)error {
}
5）通话功能
- (void)viewDidLoad {
[super viewDidLoad];
[self GetCurrentLocation_WithBlock:^{
NSLog(@"Lat ::%f,Long ::%f",[self.current_Lat floatValue],[self.current_Long floatValue]);
}];
}
6）并将以下行添加到.plist
需要在Info.plist文件中添加以下任意一个或两个键。
NSLocationWhenInUseUsageDescription
NSLocationAlwaysUsageDescription
答案 2 :(得分：0)
您可以使用zipcode调用Google APIs Maps服务获取位置：
只需在address={your zipcode}输入您的邮政编码。
答案 3 :(得分：0)
如果位置权限没有询问您何时首次启动，则无法获取当前位置。
iOS8通过LocationsServices
为我们带来了主要的API更改假设[CLLocationManager locationServicesEnabled]返回YES，
首次推出iOS应用程序[iOS7和iOS8] - locationMangers（CLLocationManager）
