1，使用定位系统时要注意下面的这几行代码

#import <UIKit/UIKit.h>

#import <CoreLocation/CoreLocation.h>

@interface LoncationViewController :

UIViewController <CLLocationManagerDelegate> {

}

2，还要注意添加包：CoreLocation.framework

关键代码实例

- (void)viewDidLoad {

    self.locationManager = [[CLLocationManager alloc] init];

    locationManager.delegate = self;

    locationManager.desiredAccuracy = kCLLocationAccuracyBest;

    [locationManager startUpdatingLocation];

}

#pragma mark CLLocationManagerDelegate Methods

- (void)locationManager:(CLLocationManager *)manager

didUpdateToLocation:(CLLocation *)newLocation

  fromLocation:(CLLocation *)oldLocation {

NSString *latitudeString = [[NSString alloc] initWithFormat:@"%g\u00B0",

newLocation.coordinate.latitude];

NSLog(@"newLocation.coordinate.latitude : %@",latitudeString);

[latitudeString release];

}

- (void)locationManager:(CLLocationManager *)manager

       didFailWithError:(NSError *)error {

    NSString *errorType = (error.code == kCLErrorDenied) ?

@"Access Denied" : @"Unknown Error";

NSLog(@"errorType : %@",errorType);

}
