Google지도에서 전체 절묘한 폴리 라인을 그릴 수 없습니다. iOS가있는 경우

Question

iOS의 Google지도에서 두 위치 사이에 경로를 만들려고합니다. 다음 코드를 사용하여 두 위치 사이에 경로를 그릴 수 있습니다. 이 코드에서는 Google지도 키와 장소 키를 사용하고 있습니다. 나는 그때가 가까워지면 시간이 올 것이다. 그러나 내가 먼 거리에 그림을 그릴 때, 멀리지도를 따라 가려하지 않는다.

내가 실수하고있는 것을 알 수 있습니까?

Answer 1

나는 GOOGLE MAPS를 사용하고 있다면이 방법을 선호합니다.

GMSPolyline *polyPath = [GMSPolyline polylineWithPath:[GMSPath pathFromEncodedPath:encodedPath]]; 

다음은 전체 코드 단편입니다.

-(void)drawPathFrom:(CLLocation*)source toDestination:(CLLocation*)destination{ 

    NSString *baseUrl = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/directions/json?origin=%f,%f&destination=%f,%f&sensor=true", source.coordinate.latitude, source.coordinate.longitude, destination.coordinate.latitude, destination.coordinate.longitude]; 

    NSURL *url = [NSURL URLWithString:[baseUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 
    NSLog(@"Url: %@", url); 
    NSURLRequest *request = [NSURLRequest requestWithURL:url]; 

    [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) { 
     if(!connectionError){ 
      NSDictionary *result  = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; 
      NSArray *routes    = [result objectForKey:@"routes"]; 
      NSDictionary *firstRoute = [routes objectAtIndex:0]; 
      NSString *encodedPath  = [firstRoute[@"overview_polyline"] objectForKey:@"points"]; 

      GMSPolyline *polyPath  = [GMSPolyline polylineWithPath:[GMSPath pathFromEncodedPath:encodedPath]]; 
      polyPath.strokeColor  = [UIColor redColor]; 
      polyPath.strokeWidth  = 3.5f; 
      polyPath.map    = _mapView; 
     } 
    }]; 

} 

Answer 2

두 경로 BTW 두 곳을 그리려면이 방법을 사용하십시오. 그 데모 swift 방법은 두 장소의 패배를 찾을 수 있습니다.

//MARK: API CALL 
func GetRoughtofTwoLocation(){ 
    let originString: String = "\(23.5800),\(72.5853)" 
    let destinationString: String = "\(24.5836),\(72.5853)" 
    let directionsAPI: String = "https://maps.googleapis.com/maps/api/directions/json?" 
    let directionsUrlString: String = "\(directionsAPI)&origin=\(originString)&destination=\(destinationString)&mode=driving" 

    APICall().callApiUsingWithFixURLGET(directionsUrlString, withLoader: true) { (responceData) -> Void in 
     let json = responceData as! NSDictionary 
     let routesArray: [AnyObject] = (json["routes"] as! [AnyObject]) 
     var polyline: GMSPolyline? = nil 
     if routesArray.count > 0 { 
      let routeDict: [NSObject : AnyObject] = routesArray[0] as! [NSObject : AnyObject] 
      var routeOverviewPolyline: [NSObject : AnyObject] = (routeDict["overview_polyline"] as! [NSObject : AnyObject]) 
      let points: String = (routeOverviewPolyline["points"] as! String) 
      let path: GMSPath = GMSPath(fromEncodedPath: points)! 
      polyline = GMSPolyline(path: path) 
      polyline!.strokeWidth = 2.0 
      polyline!.map = self.mapView 
     } 

    } 
}
