在UIWebView上加载当前的地理位置 [英] Loading current geolocation on UIWebView

问题描述

有没有一种方法可以获得用户的当前地理位置（在我的例子中是印度Bengluru），以便我可以调用Google Static Map API并在ViewController的UIWebView上加载静态地图图像。 xib

例如，

http://maps.googleapis.com/maps/api/staticmap?center=-OBTAINED_LOCATION-& zoom = 14& size = 512x512& maptype = roadmap& sensor = false

这里的OBTAINED_LOCATION应该是表示用户当前地理位置的那个。 / b>

解决方案

用户以下代码：

：

  #import< MapKit / MapKit.h> 
 #import< CoreLocation / CoreLocation.h> 
 @interface StoresMapView：UIViewController< MKMapViewDelegate，CLLocationManagerDelegate> {
 CLLocationManager * locationManager; 
} 
  

然后在 .m 中使用以下

编辑：

   - （void）setMapCenter：（CLLocationCoordinate2D）location 
 {
 NSLog（@当前位置：％f，％f，location.latitude，location.longitude）; 
 MKCoordinateRegion区域; 
 MKCoordinateSpan跨度; 
 span.latitudeDelta = 0.01; 
 span.longitudeDelta = 0.01; 
 region.span = span; 
 //location.latitude=(float *）（self.appDelegate.currentLocationLatitude）; 
 //location.latitude=self.appDelegate.currentLocationLongitude; 
 region.center = location; 
 [self._mapView setRegion：region animated：TRUE]; 
 [self._mapView regionThatFits：region]; 
 
 
 $ b #pragma mark  -  
 #pragma mark位置管理器函数
 
  - （void）locationManager：（CLLocationManager *）manager didUpdateToLocation：（CLLocation *）newLocation fromLocation：（CLLocation *）oldLocation 
 {
 NSLog（@Inside Location Delegate =％@，newLocation.coordinate）; 
 
 [self._mapView selectAnnotation：[[self._mapView annotations] lastObject] animated：YES]; 
 [self setMapCenter：newLocation.coordinate]; //调用上面定义的Metod 
 
 [self.locationManager stopUpdatingLocation]; //如果你想持续更新用户的位置
} 
 
  - （void）locationManager：（CLLocationManager *）manager didFailWithError：（NSError *）error 
 {
 NSLog（@ERROR）; 
} 
  

Is there a way where I can get the current geographic location of the user (In my case, Bengluru, India), so that I can call Google Static Map API and load the static map image on the UIWebView of the ViewController.xib

For example,
http://maps.googleapis.com/maps/api/staticmap?center=-OBTAINED_LOCATION-&zoom=14&size=512x512&maptype=roadmap&sensor=false

Here OBTAINED_LOCATION should be the one that indicates current geographic location of the user.

解决方案

User Following Code:

First access following delegates to your interface:

#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
@interface StoresMapView : UIViewController <MKMapViewDelegate, CLLocationManagerDelegate>{
CLLocationManager *locationManager;
}

Then In .m use Following

Edit:

-(void)setMapCenter:(CLLocationCoordinate2D)location
{
NSLog(@"Current Location : %f, %f",location.latitude,location.longitude);
MKCoordinateRegion region;
MKCoordinateSpan span;
span.latitudeDelta=0.01;
span.longitudeDelta=0.01;
region.span=span;
//location.latitude=(float *)(self.appDelegate.currentLocationLatitude);
//location.latitude=self.appDelegate.currentLocationLongitude;
region.center=location;
[self._mapView setRegion:region animated:TRUE];
[self._mapView regionThatFits:region];
}


#pragma mark -
#pragma mark Location Manager functions

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{   
NSLog(@"Inside Location Delegate = %@", newLocation.coordinate);    

[self._mapView selectAnnotation:[[self._mapView annotations] lastObject] animated:YES];
    [self setMapCenter:newLocation.coordinate];//Call this Metod defined above

[self.locationManager stopUpdatingLocation];//Don't use this line if u want continous updation in user's location
}

-(void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"ERROR");
}
