如何从 controller objective-c 访问按钮事件

Question

I just started to learn Objective-C and iPhone SDK programming. I have made 2 rect buttons and one label in my XIB design (it is appearing after clicking on views). I have to make code in button click event in my controller. As in c#.net we simply take button.click event (dummy code).

Like I have 2 rect buttons and their title is 8 and 9 and one label. When I will click on button 8 my label will print 8 and similarly when I will click on button 9 my label will show 9. My concern is that is how will know in controller (.m file) which button is being pressed.

Answer 1

Set the tag field of your buttons to different values, then define a method

-(IBAction)buttonPressed:(id)sender;

and inside it call [(UIView *)sender tag] . Checking that value you will know what button has been pressed.

Alternatively you may call two different methods, but since the behavior is such similar I'd prefer the first solution.
