在iOS开发中自动获取当前的位置(GPS定位)
开发环境 xcode5.0
首先我们要引入这个框架CoreLocation.framework
将这个库引进来#import <CoreLocation/CoreLocation.h>
还有他的代理方法 CLLocationManagerDelegate
GPSViewController.h
注意这里的CLLocationManager* locationmanager要设置成全局变量，要不然得不到你想要的结果哦！具体为什么，我现在还不清楚
-
#import <UIKit/UIKit.h>
-
#import <CoreLocation/CoreLocation.h>
-
@interface GPSViewController : UIViewController<CLLocationManagerDelegate>
-
-
@property(nonatomic,retain) CLLocationManager* locationmanager;
-
@end
GPSViewController.m
-
#import "GPSViewController.h"
-
-
@interface GPSViewController ()
-
-
@end
-
-
@implementation GPSViewController
-
-
@synthesize locationmanager;
-
-
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
-
{
-
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
-
if (self) {
-
-
}
-
return self;
-
}
-
-
- (void)viewDidLoad
-
{
-
[super viewDidLoad];
-
-
locationmanager = [[CLLocationManager alloc]init];
-
-
-
-
-
-
-
-
-
-
-
-
[locationmanager setDesiredAccuracy:kCLLocationAccuracyBest];
-
-
locationmanager.delegate = self;
-
NSLog(@"开始定位");
-
-
[locationmanager startUpdatingLocation];
-
-
}
-

[locationmanager stopUpdatingLocation];
