Question

I have a method @selector with parameter of type NSString. when I compile the app I get this error

No visible @interface for 'UIButton' declares the selector 'addTarget:action:
withObject:forControlEvents

The method is declared in header file.
This is the code:

 -(void)loadDetailListViewController: (NSString *)nameTable{
      //......
  }

 - (MKAnnotationView *)mapView:(MKMapView *)mapview viewForAnnotation:(id 
  <MKAnnotation>)annotation
  {
        //.....

   UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

   [rightButton addTarget:self action: @selector(loadDetailListViewController:) 
     withObject:self.nameTable forControlEvents:UIControlEventTouchUpInside];
    //here the error


        //.....
   }

I don’t know if the parenthesis are right

Answer 1

that method does not exist. This does

[rightButton addTarget:self action: @selector(loadDetailListViewController:) forControlEvents:UIControlEventTouchUpInside];

If you need to pass a string to the method, I would suggest subclassing UIButton with a string property and you can set it there. The button is passed as a parameter in your selector so you can get it and the string from there:

- (void)loadDetailListViewController:(MyCustomButtonClass *)button {

    // access the string from the button

}
