现在定位sdk比较多 ,但是如果是简单的定位的话,还是用苹果自带的方法比较简单。如果想了解百度sdk定位 点击了解百度定位(含demo) 本文 主要讲解苹果自带的定位CLLocationManager
1) 首先 在info.plist 文件中添加
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<string>app需要您的同意,才能访问位置</string>
</plist>
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<string>app需要您的同意,才能访问位置</string>
</plist>
2) 在appdelegate 中引入
#import <CoreLocation/CoreLocation.h>
3) 声明属性 引入代理
@interface AppDelegate ()<CLLocationManagerDelegate>
{
CLLocationManager *_locationManager;
}
@end
4) 初始化CLLocationManager,实现代理方法
- (void)loadLocation{
//定位管理器
_locationManager=[[CLLocationManager alloc]init];
if (![CLLocationManager locationServicesEnabled]) {
NSLog(@"定位服务当前可能尚未打开,请设置打开!");
return;
}
//如果没有授权则请求用户授权
if ([CLLocationManager authorizationStatus]==kCLAuthorizationStatusNotDetermined){
[_locationManager requestWhenInUseAuthorization];
NSLog(@"定位服务打开!");
[self startLocation];
}else{
[_locationManager requestWhenInUseAuthorization];
[self startLocation];
}
}
- (void)startLocation{
//定位管理器
//设置代理
_locationManager.delegate=self;
//设置定位精度
_locationManager.desiredAccuracy=kCLLocationAccuracyBest;
//定位频率,每隔多少米定位一次
CLLocationDistance distance=10.0;//十米定位一次
_locationManager.distanceFilter=distance;
//启动跟踪定位
[_locationManager startUpdatingLocation];
}
#pragma mark - CoreLocation 代理
#pragma mark 跟踪定位代理方法,每次位置发生变化即会执行(只要定位到相应位置)
//可以通过模拟器设置一个虚拟位置,否则在模拟器中无法调用此方法
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
CLLocation *location=[locations firstObject];//取出第一个位置
CLLocationCoordinate2D coordinate=location.coordinate;//位置坐标
NSLog(@"经度:%f,纬度:%f,海拔:%f,航向:%f,行走速度:%f",coordinate.longitude,coordinate.latitude,location.altitude,location.course,location.speed);
[self reverseGeocoder:location];
}
#pragma mark Geocoder
//反地理编码
- (void)reverseGeocoder:(CLLocation *)currentLocation {
CLGeocoder* geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
if(error || placemarks.count == 0){
NSLog(@"error = %@",error);
}else{
CLPlacemark* placemark = placemarks.firstObject;
//City 是获取城市的key
NSString * city = [[placemark addressDictionary] objectForKey:@"City"];
//SubLocality 是获取详细地址的key
NSString * country = [[placemark addressDictionary] objectForKey:@"SubLocality"];
//State 是获取省的key
NSString * provice = [[placemark addressDictionary] objectForKey:@"State"];
NSString * moreAddress = [[placemark addressDictionary] objectForKey:@"FormattedAddressLines"][0];
NSLog(@"city:%@,country:%@,provice:%@,moreAddress:%@",city,country,provice,moreAddress);
}
}];
}
5) 在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中调用
[self loadLocation];
6) 运行 查看效果
