（一）plist修改

添加如下变量

（二）新建视图用来启动Gps

此视图控制器继承CLLocationManagerDelegate

#import
#import

@interface GpsViewController : UIViewController

@end

（三）定义标签用来显示位置，并开启定位

UILabel *latitudeValue;
UILabel *longitudeValue;
CLLocationManager *locationManager;

• (void)viewDidLoad {
  [super viewDidLoad];

  self.view.backgroundColor=[UIColor redColor];
  self.view.alpha=0.5;

  UILabel *latitude=[[UILabel alloc] init];
  latitude.text=@"Latitude:";
  latitude.frame=CGRectMake(, , , );
  [self.view addSubview:latitude];

  latitudeValue=[[UILabel alloc] init];
  latitudeValue.text=@"";
  latitudeValue.frame=CGRectMake(, , , );
  [self.view addSubview:latitudeValue];

  UILabel *longitude=[[UILabel alloc] init];
  longitude.text=@"Longitude:";
  longitude.frame=CGRectMake(, , , );
  [self.view addSubview:longitude];

  longitudeValue=[[UILabel alloc] init];
  longitudeValue.text=@"";
  longitudeValue.frame=CGRectMake(, , , );
  [self.view addSubview:longitudeValue];

  //开启定位
  locationManager=[[CLLocationManager alloc] init];
  locationManager.delegate=self;
  locationManager.desiredAccuracy=kCLLocationAccuracyBest;
  locationManager.distanceFilter=kCLDistanceFilterNone;
  locationManager.allowsBackgroundLocationUpdates=YES;
  //使用期间定位
  [locationManager requestWhenInUseAuthorization];
  [locationManager requestAlwaysAuthorization];
  [locationManager startUpdatingLocation];
  // Do any additional setup after loading the view.
  }

（四）通过委托说去实时位置

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
NSLog(@"Update location");
CLLocation *newLoaction=locations[];
latitudeValue.text=[[NSString alloc] initWithFormat:@"%f",newLoaction.coordinate.latitude];
longitudeValue.text=[[NSString alloc] initWithFormat:@"%f",newLoaction.coordinate.longitude];
}

（五）用户权限检测

if (\[CLLocationManager locationServicesEnabled\]) {  
    switch (\[CLLocationManager authorizationStatus\]) {  
        case kCLAuthorizationStatusNotDetermined:  
            NSLog(@"用户尚未进行选择");  
            break;  
        case kCLAuthorizationStatusRestricted:  
            NSLog(@"定位权限被限制");  
            break;  
        case kCLAuthorizationStatusAuthorizedAlways:  
        case kCLAuthorizationStatusAuthorizedWhenInUse:  
            NSLog(@"用户允许定位");  
            break;  
        case kCLAuthorizationStatusDenied:  
            NSLog(@"用户不允许定位");  
            break;

        default:  
            break;  
    }  
}

（六）定位失败委托

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"Update error");

if(error.code == kCLErrorLocationUnknown) {  
    NSLog(@"无法检索位置");  
}  
else if(error.code == kCLErrorNetwork) {  
    NSLog(@"网络问题");  
}  
else if(error.code == kCLErrorDenied) {  
    NSLog(@"定位权限的问题");  
    \[locationManager stopUpdatingLocation\];  
}  

}

//--------------------------------方法封装-----------------------------------//

通过自定义委托来实现获取地址后的数据传递

LLLocation.h

#import
#import

@protocol LocationHandlerDelegate

@required
-(void) didUpdateToLocation:(CLLocation*)newLocation;

@end

@interface LLLocation : NSObject
{
CLLocationManager *locationManager;
}

@property(nonatomic,strong) id delegate;

+(id)getSharedInstance;
-(void)startUpdatingLocation;
-(void) stopUpdatingLocation;

@end

LLLocation.m

#import "LLLocation.h"

@interface LLLocation()

-(void)initLocationManager;

@end

@implementation LLLocation

• (LLLocation *)getSharedInstance
  {
  static LLLocation *location = nil;
  static dispatch_once_t onceToken;
  dispatch_once(&onceToken, ^{
  location = [[LLLocation alloc] init];
  [location initLocationManager];
  });
  return location;
  }

-(void)initLocationManager
{
NSLog(@"init");
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
}

-(void)startUpdatingLocation
{
[locationManager startUpdatingLocation];
}

-(void) stopUpdatingLocation
{
[locationManager stopUpdatingLocation];
}

• (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
  {
  [locationManager stopUpdatingLocation];
  NSLog(@"Update gps");
  if ([self.delegate respondsToSelector:@selector
  (didUpdateToLocation:)])
  {
  [self.delegate didUpdateToLocation:locations[]];

  }
  }

@end

调用

LLLocation \*location=\[LLLocation getSharedInstance\];  
\[location startUpdatingLocation\];  
\[location setDelegate:self\];

上述调用文件中要实现自定义的委托，如下

@interface GpsViewController ()

@property(nonatomic,strong) CLLocationManager *locationManager;

@end

-(void) didUpdateToLocation:(CLLocation*)newLocation
{
latitudeValue.text=[[NSString alloc] initWithFormat:@"%f",newLocation.coordinate.latitude];
longitudeValue.text=[[NSString alloc] initWithFormat:@"%f",newLocation.coordinate.longitude];

}

PS：在应用过程中会出现委托并未调用情况，如果按上述步骤进行，委托还未调用，则建议查看CLLocationManagerDelegate的定义，确定委托方法是否在此ios版本中适用；或者把CLLocationManager *locationManager定义为强引用的属性试试
