UITableView到UIScrollView

Question

if ([cell.imageView.image isEqual:[UIImage imageNamed:@"1.png"]]) {
// Do something 1
} else {
// Do something 2
}

Can this code be converted to for UIIScrollView?

Answer 1

That depends, do you have a pointer to the item inside of the scrollView you want to co something with. If so you could change it like so (assuming all subviews of the scrollview are UIImageViews):

for (int i = 0; i < [scrollView.subviews count]; i++) {
    UIImageView *imageView = [scrollView.subviews objectAtIndex:i];

    if ([imageView.image isEqual:[UIImage imageNamed:@"1.png"]]) {
        // Do something 1
    } else {
        // Do something 2
    }
}
