在目标c文件中有一个按钮（来自pod），并从swift继承它

Question

So I am currently using an SDK which has a XIB file and I have connected a button to its view controller as you see in the code below. I have done this within the pod library itself

- (IBAction)testButton:(UIButton *)sender {
NSLog(@"test");
}

I have then subclassed the class which I placed this method in my swift file. However, I am unable to access this button from the swift file itself. How do I override this button's functionality from my swift file itself?

class MyLoginViewController: BLoginViewController {

override func viewDidLoad() {
    super.viewDidLoad()

}

//I am unable to override the button in this view controller

Answer 1

add this line in your BLoginViewController.h

- (IBAction)testButton:(UIButton *)sender;

now you can override this method in your MyLoginViewController like this

override func test(_ sender: UIButton!) {

}
