How to trigger UIButton action programmatically

Question

I have several buttons in one class and their actions are separate. I created the instance of that class in another class, and I have the UIButton array in the 2nd class. I want to call each button's action programmatically. Is there any way to do this in iOS?

Answer 1

Swift 3.0/4.0/5.0

button.sendActions(for: .touchUpInside)

Answer 2

UIButton has a method to invoke the targets/selectors that are linked to a certain control event:

[button sendActionsForControlEvents:UIControlEventTouchUpInside];
