手机定位 coco2d开发
手机定位 需要实现代理CLLocationManagerDelegate，MKReverseGeocoderDelegate
并导入CoreLocation 框架。
代理使用方法 如下：
#pragma mark - 获取城市名称
// iso 5.0 以下版本使用此方法
- (void)startedReverseGeoderWithLatitude:(double)latitude longitude:(double)longitude{
CLLocationCoordinate2D coordinate2D;
coordinate2D.longitude = longitude;
coordinate2D.latitude = latitude;
MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate2D];
self.reverseGeocoder = geoCoder;
[geoCoder release];
self.reverseGeocoder.delegate = self;
[self.reverseGeocoder start];
}
#pragma mark -
- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
{
NSString *thoroughfare=placemark.thoroughfare;
if (thoroughfare) {
self.locationLabel.text = thoroughfare;
}
}
- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error
{
NSLog(@"获取失败");
}
// IOS 5.0 及以上版本使用此方法
- (void)locationAddressWithLocation:(CLLocation *)locationGps
{
CLGeocoder *clGeoCoder = [[CLGeocoder alloc] init];
self.geoCoder = clGeoCoder;
[clGeoCoder release];
[self.geoCoder reverseGeocodeLocation:locationGps completionHandler:^(NSArray *placemarks, NSError *error)
{
NSLog(@"error %@ placemarks count %d",error.localizedDescription,placemarks.count);
for (CLPlacemark *placeMark in placemarks)
{
NSLog(@"地址：%@",placeMark.locality);
NSLog(@"地址：%@",placeMark.thoroughfare);
NSLog(@"地址：%@",placeMark.subLocality);
self.locationLabel.text = placeMark.thoroughfare;
}
}];
}
#pragma mark - location Delegate
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"定位出错");
}
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
if (!newLocation) {
[self locationManager:manager didFailWithError:(NSError *)NULL];
return;
}
if (signbit(newLocation.horizontalAccuracy)) {
[self locationManager:manager didFailWithError:(NSError *)NULL];
return;
}
[manager stopUpdatingLocation];
NSLog(@"%f,%f",newLocation.coordinate.latitude,newLocation.coordinate.longitude);
_coordinate.latitude = newLocation.coordinate.latitude;
_coordinate.longitude = newLocation.coordinate.longitude;
self.gpsLabel.text = [NSString stringWithFormat:@"%f,%f",newLocation.coordinate.latitude,newLocation.coordinate.longitude];
//解析并获取当前坐标对应得地址信息
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 5.0) {
[self locationAddressWithLocation:newLocation];
}else {
[self startedReverseGeoderWithLatitude:newLocation.coordinate.latitude
longitude:newLocation.coordinate.longitude];
}
}
