ios - Integration Objective C Protocols with Swift -

-

I'm new to fast and I need some help to integrate a component AP PictureView (written in Objective-C). Link to the component:

But I have no success, because there is a protocol: AKPickerViewDelegate that do not work in swift: 

  @ Square AKPickerView; @protocol AKPickerViewDelegate & lt; NSObject & gt; @optional - (NSString *) pickerView: (AKPickerView *) PickView title forItem: (NSInteger) item; - (NSUIENTER) Number of items input list: (Acquisitionview *) Procedure; - (Zero) PickView: (Ekpereviewview *) PickViews selected: Item (NSInteger) item; In SWIFT I wrote this code:  
  View category Controller: UIViewController, AKPickerViewDelegate {var pickerView: AKPickerView = AKPickerView () var Title: NSArray = ["Jeniro", "Faviriro", "Marso  
 
 And I have implemented this method: 
 
  Function number of items inappropriateview 'S PictureView!) - & gt; Int {return self.titles.count} func pickerView (pickerView: AKPickerView, titleForItem item: NSInteger) - & gt; NSString {return SoftTitles [Item] as NSString}  
 
 but the compiler shows this error: 
 
  corresponds to type 'ViewController' protocol No, A's PictureViewdelete ' 
 
 Thank you for some help!

I need the method seen in the link AKPickerViewDelegate . 

  @protocol AKPickerViewDelegate & lt; NSObject & gt; @required - (NSUInteger) numberOfItemsInPickerView: (AKPickerView *) PickView; - (NSString *) PickView: (AKPickerView *) PickerWeight Title ForItem: (NSInteger) Item; @ Option - (zero) PickerView: (AcquisitionView *) PickViewed Selection ITM: (NSINTGAR) Item; @end

So fast you need to implement them. Apply these methods as below and remove this error 

  func numberOfItemsInPickerView (pickerView: AKPickerView!) - & gt; UInt {return self.titles.count} func pickerView (pickerView: AKPickerView !, Title ForItem Item: Int) - & gt; String! {Return self.titles [item]}

Note You have to add them to the bridging headers. Just type it #import "AKPickerView.h" in swift-bridging-header h

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
