iOS Constraining the area for text in an UILabelView

[gwelmarten]

Hi
I've got a UILabelView that takes up a large amount of space (and it has to do this).
However, I want the text within it to stay within a small area within it. I've had a look around, and I see there is a method fro containing the area text can occupy in a text view - is there something similar for UILabelView? So I can keep text within a CGRect of the label view?
Thanks for your help,
Sam

Why does it have to take up a large amount of space?

Because of an animation I'm running on it. I have thought about resizing it, but no-one in my team can think of a way of then handling the animation.
So is there a way of handling a constraint? I couldn't see one in the class reference, so I presume no.

Just realised I was looking in the Mac class reference - in the iOS one, I saw:
textRectForBounds:limitedToNumberOfLines:
I think something like this will work, so I'm going to try. Any views on if it will?

No idea! Give it a try and report back.

What kind of animation? Have you considered animating a UIView and having the UILabel (there is no UILabelView, by the way) as a subview?

Hmm...no luck. To create the UILabelView, I've got:

    question = [[UILabel alloc] init];
    question.frame = CGRectMake(0, 0, 480, 300);
    question.textAlignment = UITextAlignmentCenter;
    question.text = @"Loading...";
    question.lineBreakMode = UILineBreakModeWordWrap;
    question.numberOfLines = 4; //Or whatever you want
    question.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"x019xm2.png"]];
    [question drawTextInRect:CGRectMake(100, 100, 50, 50)];
    [self.view addSubview:question];

Now it hasn't worked, I quickly googled drawTextInRect and others seem to have similar code. Is the CGRect still based on the screen size - not the size of the UILabelView?

Hi Dejo
Yes, we did, and we tried it. And no, it didn't work for what we are trying to do.

Oh...just read the rest of the class reference, and that method is only for subclassing.
So it won't work in the way I was trying.
I'll have to try and find another way. If I do, I'll post it back here for your interest.

Again, I ask: what kind of animation?
