How to trigger UIButton action programmatically

I have multiple buttons in the same class and their actions are separate. I created an instance of this class in another class and I have a UIButton array in the second class. I want to call each button programmatically. Is there a way to do this in iOS?

UIButton has a method to call target / selectors associated with a specific control event:



[button sendActionsForControlEvents:UIControlEventTouchUpInside];

button.sendActions(for: .touchUpInside)

You can just call the action method of the first class as an instance method from other classes by passing the UIbutton id

eg: in the first class " ClassA "

- (IBAction)classAbuttonAction1:(id)sender;
- (IBAction)classAbuttonAction2:(id)sender;

from another class

UIButton *bClassButton = [[UIButton alloc]init];    
ClassA *instance = [[ClassA alloc]init];

[instance classAbuttonAction1:bClassButton];
[instance classAbuttonAction2:bClassButton];
