iOS地理定位

-引入头文件

#import <CoreLocation/CoreLocation.h>

-声明变量

@property (nonatomic, strong)CLLocationManager *locationManager;

-实现代理方法

@interface LocationTool : NSObject <CLLocationManagerDelegate>

-初始化locationManager

- (instancetype)init
{
self = [super init];
if (self) {
_locationManager = [[CLLocationManager alloc]init];
_locationManager.delegate = self;
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
_locationManager.distanceFilter = kCLDistanceFilterNone;

if ([[UIDevice currentDevice].systemVersion floatValue] >= 8.0) {
[_locationManager requestWhenInUseAuthorization];
}

}
return self;
}

-实现代理方法

#pragma mark CLLocationManagerDelegate
-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error{
NSLog(@"定位出错");
}

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
NSLog(@"定位成功");
}

-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{
switch (status) {
case kCLAuthorizationStatusNotDetermined:  //用户还没有被请求获取授权
if ([_locationManager respondsToSelector:@selector(requestAlwaysAuthorization)])
{
[_locationManager requestWhenInUseAuthorization];
}
NSLog(@"kCLAuthorizationStatusNotDetermined");
break;
default:
break;
}
}

-支持iOS8

添加：NSLocationWhenInUseUsageDescription, NSLocationAlwaysUsageDescription
