I create a UIButton in coding phase and never use Interface Builder so how can I call touch up inside event to hook up with any method in coding phase?
UIButton
touch up inside
[button addTarget:self action:@selector(BtnPressed:) forControlEvents:UIControlEventTouchUpInside];
Swift 3:
button.addTarget(self, action: #selector(ViewControllerName.BtnPressed), for: .touchUpInside)
