I completely agree, and I think you *should* know what you're looking for.
That's why my book *explains* scroll views to you rather than just giving you
blind instructions to follow or parroting the documentation, plus by the time
you get to them you understand the *concepts* on which they are based.
It is a *lot* easier to understand scroll views if you create and populate them
in code before dealing with scroll views in the nib. So I suggest you scrap
what you've got and start with this:
UIScrollView* sv = [[UIScrollView alloc] initWithFrame:
[[UIScreen mainScreen] applicationFrame]];
self.view = sv;
CGFloat y = 10;
for (int i=0; i<30; i++) {
UILabel* lab = [[UILabel alloc] init];
lab.text = [NSString stringWithFormat:@"This is label %i", i+1];
[lab sizeToFit];
CGRect f = lab.frame;
f.origin = CGPointMake(10,y);
lab.frame = f;
[sv addSubview:lab];
y += lab.bounds.size.height + 10;
[lab release];
}
CGSize sz = sv.bounds.size;
sz.height = y;
sv.contentSize = sz; // This is the crucial line
[sv release];
You'll need a view-based app to start with; put that in the loadView method
(not viewDidLoad), so that the scroll view *is* the view controller's view. The
crucial move, as the comment notes, is that we tell the scroll view how large
its content view is to be. If we omit this step, the scroll view won't be
scrollable; the window will appear to consist of a static column of labels.
