IOS UIButton with IBAction

I have create some buttons on for loop on below code.

UIView *buttonsView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, _viewEmoji.frame.size.width, 35)];
    [buttonsView setBackgroundColor:[UIColor greenColor]];
for (int i = 0; i < myObject.count; i ++) {
        UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
        [button setFrame:CGRectMake(35*i + 5, 0, 35, 35)];
        [button setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@", [myObject objectAtIndex:i]]] forState:UIControlStateNormal];
        [button addTarget:self action:@selector(clickButton:) forControlEvents:UIControlEventTouchUpInside];
        [buttonsView addSubview:button];
    }

And now, How to I can click button to handle event.

Every button was clicked, It will handle 1 event.

Ex: if I have 2 buttons was created by for loop. When I click button 1, it's will log 1, When I click button 2, it's will log 2.

do like 

UIView *buttonsView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, _viewEmoji.frame.size.width, 35)];
[buttonsView setBackgroundColor:[UIColor greenColor]];
for (int i = 0; i < myObject.count; i ++) {
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setFrame:CGRectMake(35*i + 5, 0, 35, 35)];
    [button setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@", [myObject objectAtIndex:i]]] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(clickButton:) forControlEvents:UIControlEventTouchUpInside];
    // set the tag for identify which button you pressed
     button.tag = i; // else use -->  [myObject objectAtIndex:i]
    [buttonsView addSubview:button];
}

  //here add your buttonsView to mainview
self.view addsubview(buttonsView)

// for button action
-(void)clickButton:(UIButton*)sender
{
   NSLog(@" Index: %d ", sender.tag);
   [sender setBackgroundImage:[UIImage imageNamed:@"XXX.png"] forState:UIControlStateNormal];

}
