Question

I have a lot of button inside a UIScrollView and i am trying to get their position on button click. Here is my code:

UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(2, 0, 262, 748)];
scrollView.contentSize=CGSizeMake(262, 816);
scrollView.bounces=NO;
scrollView.delaysContentTouches=YES;

buton1 = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
buton1.frame = CGRectMake(2, 0, 262, 102);
buton1.bounds = CGRectMake(2, 0, 262.0, 102.0);
[buton1 setTag:1];
[buton1 setImage:[UIImage imageNamed:@"left_gride.png"] forState:UIControlStateNormal];
[buton1 addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
     [scrollView addSubview:buton1];

and

-(void) buttonClick:(UIButton*)button{
if ([button tag]==1)
{
     NSLog(@"position:%d",buton1.frame.origin.x);
}
else
{
    NSLog(@"position:%d",buton2.frame.origin.y);
}

}

What is wrong with my code.Thanks.

I also tried with :

-(void) buttonClick:(UIButton*)button{
if ([button tag]==1)
{
     NSLog(@"position:%d",buton1.frame.origin.x);
}
else
{
    NSLog(@"position:%d",buton2.frame.origin.y);
}

-(void) buttonClick:(UIButton*)button{
if ([button tag]==1)
{
     NSLog(@"position:%d",button.frame.origin.x);
}
else
{
    NSLog(@"position:%d",button2.frame.origin.y);
}

But i just get the same.Position 0;

Your code looks fine. The only thing – you use wrong format specifier in NSLog. As coordinates are floating point numbers you should use %f instead of %d:

NSLog(@"position:%f",buton1.frame.origin.x);
