Instead of creating an IBOutlet, you need to do IBAction

to directly receive the click event

Check out this image ...
enter image description here



This is the file .m

where I directly createIBAction

and if you want to give the clickable event programmatically then follow @Nicolas Buquet's answer

Add this to your code:

[OkBtn addTarget:self action:@selector(okButtonTapped:) forControlEvents:UIControlEventTouchUpInside];

and add this method to your class:



- (void)okButtonTapped:(UIButton *)sender {
NSLog(@"Ok button was tapped: dismiss the view controller.");
}

The method okButtonTapped:

will be called when you press the button and remove your finger (the "up" part).

Create IBAction

for NSButton

. And connect IBAction

to the button.

in an interface file (.h) file,

- (IBAction) okButtonAction : (id) sender;

and in your implementation file (.m)

- (IBAction) okButtonAction : (id) sender {
   NSLog(@"OK Button action here");
}
