import UIKit
import Toolbar
class ViewController: UIViewController {
lazy var toolbar: Toolbar = {
let toolbar: Toolbar = Toolbar([
Toolbar.Item(title: "BUTTON", target: nil, action: #selector(test(_:))),
Toolbar.Item(title: "BUTTON", target: nil, action: nil),
Toolbar.Item(title: "BUTTON", target: nil, action: nil)
])
return toolbar
}()
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = .systemBackground
self.view.addSubview(self.toolbar)
}
@objc func test(_ sender: Any) {
print("hello")
}
}
After I press the first toolbar button the app crashes with:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSNull test:]: unrecognized selector sent to instance 0x1de715eb0'
terminating with uncaught exception of type NSException

I can't figure out how I am calling the test function incorrectly?
CodePudding user response:
Instead of:
Toolbar.Item(title: "BUTTON", target: nil, action: #selector(test(_:))),
Try:
Toolbar.Item(title: "BUTTON", target: self, action: #selector(test(_:))),
