SWIFT：尝试使用目标c类的委托方法

Question

I have an existing Objective-C SDK (AugmentedKit SDK) . I am trying to use it with Swift . AugmentedKit SDK has a class called ' AKSurfaceView ' that implements a delegate to ' AKViewDataSource ' protocol.

@class AKSurfaceView;
@protocol AKViewDataSource;

@protocol AKViewDelegate<AKViewDataSource>

AKViewDataSource looks like this:

@protocol AKViewDataSource<NSObject>
@required
-(AKMarkerTemplate*) viewforMarker:(AKMarker*) marker; 

I've created a briging file, implemented other methods from AKSurfaceView , etc. - everything works fine but when I try to add a reference of the AKViewDelegate to my UIViewControllerClass it ends in a compile error:

"Type POIViewController does not conform to protocol ' AKViewDataSource '"

My implementation looks like this:

class POIViewController: UIViewController, AKViewDelegate {

My implementation of ' viewforMarker ' in SWIFT looks like this:

func viewforMarker(marker:AKMarker) -> AKMarkerTemplate{
    var markerView:SimpleMarker = SimpleMarker(frame: CGRectMake(0, 0, 230, 80))
    markerView.title.text = marker.markerName
    return markerView
}

Could please anybody help my to figure out how I have to implement ' viewforMarker ' so the delegate recognise it?

Answer 1

它看起来像你的AKViewDelegate是的子类AKViewDataSource ，在这种情况下，你将不得不顺应AKViewDelegate和AKViewDataSource ，这意味着你将必须实现两个协议的必要方法。

Answer 2

确保已在Bridging-Header.h导入了Obective-C类，并在swift类中添加了以下内容：

markerView.delegate = self
