Reciever SKViaPoint for class message is a forward declaration

问题

I was trying to make an instance of SKViaPoint with

SKViaPoint *point = [SKViaPoint viaPoint:1 withCoordinate:coordinate];

But I am getting a following error:

So "No known class method for selector".

I checked and I do have the latest version of Skobbler SDK, but I also checked and there is no actual ViaPoint.h. Not in mine neither in the Demo project.

So Im wondering is there anything else I should import in order to be able to make SKViaPoint instance?

回答1:

Ok, what solved it was importing the actual class, from SKMaps framework. Importing framework only didn't do the trick

#import <SKMaps/SKViaPoint.h>

回答2:

Unfortunately, in the 2.5 Swift build, SKMaps.h in SKMaps.framework/Headers is missing some imports: SKViaPoint, SKViaPointState and SKSearch. You can add them manually or use the header found here.

In the next update we'll fix this issue.
