iOS8以前使用CoreLocation定位1、首先定义一个全局的变量用来记录CLLocationManager对象,引入CoreLocation.framework使用#import <CoreLocation/CoreLocation.h>1 @property (nonatomic, strong) CLLocationManager *locationManager; 2、初始化CLLocationManager并开始定位 self.locationManager = [[CLLocationManager alloc]init];_locationManager.delegate = self;_locationManager.desiredAccuracy = kCLLocationAccuracyBest;_locationManager.distanceFilter = 10;[_locationManager startUpdatingLocation]; 3、实现CLLocationManagerDelegate的代理方法(1)获取到位置数据,返回的是一个CLLocation的数组,一般使用其中的一个 - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{ CLLocation *currLocation = [locations lastObject]; NSLog(@"经度=%f 纬度=%f 高度=%f", currLocation.coordinate.latitude, currLocation.coordinate.longitude, currLocation.altitude);} (2)获取用户位置数据失败的回调方法,在此通知用户- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{ if ([error code] == kCLErrorDenied) { //访问被拒绝 } if ([error code] == kCLErrorLocationUnknown) { //无法获取位置信息 }} 4、在viewWillDisappear关闭定位 - (void)viewWillDisappear:(BOOL)animated{ [super viewWillDisappear:animated]; [_locationManager stopUpdatingLocation];} iOS8中使用CoreLocation定位1、在使用CoreLocation前需要调用如下函数【iOS8专用】:iOS8对定位进行了一些修改,其中包括定位授权的方法,CLLocationManager增加了下面的两个方法:(1)始终允许访问位置信息- (void)requestAlwaysAuthorization;(2)使用应用程序期间允许访问位置数据- (void)requestWhenInUseAuthorization;示例如下: self.locationManager = [[CLLocationManager alloc]init];_locationManager.delegate = self;_locationManager.desiredAccuracy = kCLLocationAccuracyBest;_locationManager.distanceFilter = 10;[_locationManager requestAlwaysAuthorization];//添加这句[_locationManager startUpdatingLocation]; 2、在Info.plist文件中添加如下配置:(1)NSLocationAlwaysUsageDescription(2)NSLocationWhenInUseUsageDescription
