Create IBOutlets and IBActions programmatically [duplicate]

Question

I want to create IBOutlets and IBActions in code rather than with the interface builder.

Let's say I've got a button on my UI called btnDisplay, and a method in my code called displayMessage. What would be the code I'd have to write to make it so that when btnDisplay is tapped, displayMessage runs?

Answer 1

The way to do that with no outlets would be to give the button a tag in IB, say 128. Then:

UIButton *btnDisplay = (UIButton *)[self.view viewWithTag:128];
[btnDisplay  addTarget:self action:@selector(pressedBtnDisplay:) forControlEvents:UIControlEventTouchUpInside];

Then implement:

- (void) pressedBtnDisplay:(id)sender {
}
