Question

Is it possible to loop through all the UILabels in my UIScrollview and change the color?

Answer 1

Assuming they’re all subviews (first-level children) of the scroll view, not of container views inside it…

for(UIView *subview in theScrollView.subviews)
    if([subview isKindOfClass:[UILabel class]])
        [(UILabel *)subview setTextColor:[UIColor whateverColor]];

If the labels are inside other views inside the scroll view, you’ll have to recurse into each of the subviews and do the same thing, but that’s a pretty simple step from the above. Example:

- (void)recolorLabelSubviews:(UIView *)view
{
    for(UIView *subview in view.subviews)
    {
        if([subview isKindOfClass:[UILabel class]])
            [(UILabel *)subview setTextColor:[UIColor whateverColor]];
        else
            [self recolorLabelSubviews:subview];
        // this doesn't handle the case where you have a label as a subview of a label
        // if for some reason you're doing that, just move the [self recolorEtc:] call out of the "else" block
    }
}

// then, wherever you want to recolor every label in the scroll view...

[self recolorLabelSubviews:theScrollView];
