模拟低和高GPS精度 [英] Simulate Low and Hight Gps Accuracy

问题描述

我做了一个.gpx文件来模拟IOS模拟器上的路由，现在我想模拟水平精度，我该如何做到这一点？ p

如下是摘录我的.gpx文件：

 <？xml version =1.0？> 
< gpx> 
< wpt lat = -  23.772830lon = -  46.689820/> //如何增加水平精度7米，例如
  < / gpx> 
  

如果我运行所有gps点返回水平精度5米，否则我可以改变它。我从viewController中调用了一个方法（我的是一个按钮，但显然你可以使用一个gestureRecognizer或者其他的方法）。

我将viewController设置为LocationManagerDelegate，但您可以放入您正在使用的代理而不是self。

   - （IBAction）simulateAccuracy：（id）sender {
 CLLocationCoordinate2D newCoor = CLLocationCoordinate2DMake（someLat，someLng）; 
 CLLocation * newLoc = [[CLLocation alloc] initWithCoordinate：newCoor altitude：someAlt 
 horizo​​ntalAccuracy：TheAccuracyYouWantToTest verticalAccuracy：ditto timestamp：nil]; 
 NSArray * newLocation = [[NSArray alloc] initWithObjects：newLoc，nil]; 
 [self locationManager：myLocationManager didUpdateLocations：newLocation]; 
} 
  

I did a .gpx file to simulate a route on IOS simulator, now i wanna simulate the horizontal accuracy how I can do this?

as follow is an excerpt of my .gpx file:

<?xml version="1.0"?>
<gpx>
    <wpt lat="-23.772830" lon="-46.689820"/> //how add horizontal accuracy 7 meters for example
    <wpt lat="-23.774450" lon="-46.692570"/> //and here horizontal accuracy of 2 metters for example
    <wpt lat="-23.773450" lon="-46.693530"/> //and here 19 meters
</gpx> 

if I run all gps points return horizontal accuracy of 5 meters, I can change this otherwise.

解决方案

I did this with a method call from the viewController (mine is a button, but obviously you could use a gestureRecognizer or whatever).

I have my viewController set as the LocationManagerDelegate, but you can put in the delegate you're using instead of "self"

- (IBAction)simulateAccuracy:(id)sender {
    CLLocationCoordinate2D newCoor = CLLocationCoordinate2DMake(someLat, someLng);
    CLLocation *newLoc = [[CLLocation alloc]    initWithCoordinate:newCoor altitude:someAlt
    horizontalAccuracy:TheAccuracyYouWantToTest verticalAccuracy:ditto timestamp:nil];
    NSArray *newLocation = [[NSArray alloc] initWithObjects:newLoc,nil];
    [self locationManager:myLocationManager didUpdateLocations:newLocation];
}
