I have many buttons in UIScrollView, and I am trying to get their position on button click. This 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
< p>
-(void) buttonClick:(UIButton*)button{
if ([button tag]==1)
{
NSLog(@"position: %d",buton1.frame.origin.x);
}
else
{
NSLog(@"position:%d",buton2.frame.origin.y) ;
}
}
What’s wrong with my code. Thank you.
I also tried:
-(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 get the same. Position 0;
Your code looks good. The only thing-you used the wrong format specifier in NSLog. Since the coordinates are floating point numbers, you should use %f instead of %d:
NSLog(@"position:%f",buton1.frame.origin.x);
