具体地址计算路由

问题描述：

我使用的计算距离这两个代码点（公里或英里）具体地址计算路由

-(void) CalculateDistance { 

    CLLocation *startLocation = [[CLLocation alloc] initWithLatitude:[self.address.originlatitude doubleValue] longitude:[self.address.originlongitude doubleValue]]; 

    CLLocation *endlocation = [[CLLocation alloc] initWithLatitude:[self.address.destinationlatitude doubleValue] longitude:[self.addresse.destinationlongitude doubleValue]]; 



    if (self.address.origin && self.address.origin.length > 0) { 

     CLLocationDistance calc = [startLocation distanceFromLocation:endlocation]; 

     double totalDistance = 0.0; 
     double totalMileage = 0.0; 

     totalDistance = totalDistance + (calc/1000); 
     totalMileage = totalMileage + (calc/1609); 



     if (self.address.distanceKind && ![self.address.distanceKind isEqualToString:@"mi"]) { 
      self.distanceTextField.text = [self.numberType stringFromNumber:[NSNumber numberWithFloat: totalDistance]]; 
      self.address.distance = [NSDecimalNumber decimalNumberWithString:self.distanceTextField.text]; 
     }else if (self.address.distanceKind &&! [self.address.distanceKind isEqualToString:@"km"]){ 
      self.distanceTextField.text = [self.numberType stringFromNumber:[NSNumber numberWithFloat: totalMileage]]; 
      self.address.distance = [NSDecimalNumber decimalNumberWithString:self.distanceTextField.text]; 

     } 


    }

代码工作正常，但计算出的距离之间不正确，因为根据车的路线不计算example.Basically与此代码mapView只绘制一条直线，并没有绘制一个正确的目的地。任何人都可以帮助我根据路线计算距离，我可以采取哪些措施？

改为使用'MKDirections'和'MKDirectionsRequest'。 – Larme

@Larme我怎么能从问题开始编码？我想看看其他的*问题，但不成功 – breadevelopment

你需要计算一个itinary。有很多关于这方面的问题。 – Larme

答

-(void)DistanceTwoLocation 
{ 
    **//This is current location take code LocationOne** 

CLLocation *LocationOne = [[CLLocation alloc] initWithLatitude:Location_Manager.location.coordinate.latitude longitude:Location_Manager.location.coordinate.longitude]; 

**//This is current location take code LocationTwo** 

CLLocation * LocationTwo = [[CLLocation alloc] initWithLatitude:[yourLatValue] longitude:[yourLongValue]; 

CLLocationDistance DistanceCalc = [LocationOne distanceFromLocation: location]; 

DistanceCalc = DistanceCalc/1000; 

NSLog(@“%@”,[NSString stringWithFormat:@"Dist:%.2f Km",distance]); 
} .
