在运行时设置位置模拟器City / GPX

Question

Is there a method to programmatically change the location simulator city during runtime? For example this would allow tests to simulate London or Tokyo.

The image below shows how to switch between locations (GPX files) manually. How can I achieve this result programmatically while the app is running?

Answer 1

Alternate way to set location is by swizzling 'location' of 'CLLocationManager' class. In obj-c,

+(void) load {
   // replace 'location' with 'custom_location' method
 }

Then implement custom_location method with whatever the location you want to set by simply changing 'kMockedLatitude' and 'kMockedLongitude' variables.

//Portland, USA
CLLocationDegrees kMockedLatitude = 45.52306;
CLLocationDegrees kMockedLongitude = -122.67648;

-(CLLocation *)custom_location  
{  
   return [[CLLocation alloc] initWithLatitude:kMockedLatitude longitude:kMockedLongitude];
}

This will work even in iOS device.
