我做项目时需要用定位功能,当时考虑过 百度和高的. 由于功能模块比较单一,就用的苹果自带的定位.
直接粘贴复制到项目里就可以了;
第一步 : 导入头文件
#import<CoreLocation/CoreLocation.h
遵守代理 CLLocationManagerDelegate协议
创建 属性 @property (nonatomic, strong) CLLocationManager* locationManager;//定位
2. 直接调用这个方法 就可以 实现 定位功能
-(void)PositioningCity {
if([CLLocationManager locationServicesEnabled]){
if(!_locationManager){
self.locationManager = [[CLLocationManager alloc] init];
if([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)]){
[self.locationManager requestWhenInUseAuthorization];
[self.locationManager requestAlwaysAuthorization];
}
//设置代理
[self.locationManager setDelegate:self];
//设置定位精度
[self.locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
//设置距离筛选
[self.locationManager setDistanceFilter:100];
//开始定位
[self.locationManager startUpdatingLocation];
//设置开始识别方向
[self.locationManager startUpdatingHeading];
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0){
[_locationManager requestWhenInUseAuthorization]; //调用了这句,就会弹出允许框了.
}
}
}else{
UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"提示" message:@"您没有开启定位功能" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *alert = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alertVC addAction:alert];
}
}
#pragma mark - CLLocationManangerDelegate
//定位成功以后调用
- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
[self.locationManager stopUpdatingLocation];
CLLocation* location = locations.lastObject;
[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);
locationCity = @"南京";
}else{
CLPlacemark* placemark = placemarks.firstObject;
NSLog(@"placemark:%@",[[placemark addressDictionary] objectForKey:@"City"]);
NSString *cityStr = [[placemark addressDictionary] objectForKey:@"City"];
locationCity = [cityStr substringToIndex:cityStr.length - 1];//城市
// [self weatherHttplocation];
// UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"当前位置" message: [NSString stringWithFormat:@"placemark:%@",[placemark addressDictionary]]preferredStyle:UIAlertControllerStyleAlert];
// UIAlertAction *alert = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
//
//
// }];
// [alertVC addAction:alert];
// [self]
}
}];
// [self weatherHttplocation ];
}
