My problem is after selecting other button first button does not unhighlight.please guide me how to do it.

Answer 1

declare a variable button tempBtn in your .h , alloc it and then perform this.

-(IBAction)sizeBtnClicked:(UIButton*)btn{
         [tempBtn setHighlighted:NO];
         [btn setHighlighted:YES];
         tempBtn=btn ;
        [self performSelector:@selector(doHighlight:) withObject:btn afterDelay:0];

    }
