Set Button selector (on click event) at runtime ? (Cocoa : Mac Project)

Question

Any idea how to set button selector at runtime (on click event) for mac (Not IOS)

I have a view controller with a button declared as outlet :

#import <         


        

Answer 1

You shall look at the NSControl class reference (from which NSButton inherits) for two separate methods setTarget: and setAction:.

You can do something like this in your code:

[MyBtn setTarget:self];
[MyBtn setAction:@selector(doStuff)];

take a look also at this answer.

Answer 2

those two methods are what you are looking for.

• (void)setTarget:(id)target;
• (void)setSelector:(SEL)selector;

================

[myButton setSelector:@selector(myButtonClickEvent:)];


-(void) myButtonClickEvent:(id) sender{
       NSLog(@"button:%@ be clicked. :)", sender);
}
