What is the most concise and semantic way to lay out a paragraph of text of variable length for IOS7?

Question

As far as I know, laying out paragraphs can be done with:

a) UITextView

• Resizing the textview to fit the content in didlayoutsubviews
  • Example here: Weird thing occurs when using sizetofit of a UITextView in IOS7

b) UILabel

• Setting the Lines to 0, using sizetofit
  • Example here: Multiple lines of text in UILabel

However, I am unable to get either of these to work in IOS7 (having previously used them in ios6.x). There must be a definitive and clear way to just lay out a paragraph, its such a seemingly simple task.To be specific, this is just a paragraph of text that is:

• non-editable
• variable length
• Works consistently whether using storyboards or code only

So please, what is the way to do this?

Answer 1

UITextView works fine on iOS 7. If you don't use Auto Layout, then calling sizeToFit on UITextView object should be enough. If you do use Auto Layout, then make a height constraint on UITextView object and set its constant in code in the following way:

CGSize sizeThatFits = [self.textView sizeThatFits:CGSizeMake(yourAvailableWidth, MAXFLOAT)];
self.textViewHeightConstraint.constant = ceilf(sizeThatFits.height);

I've seen some problems with UILabel recently, e.g. Lines missing from tall UILabel when embedding NSTextAttachment

Answer 2

With the UILabel, I was able to to get this working by:

• setting the lines to 0
• setting my line break mode to word wrap
• ensuring that the height constraint is set to a "greater than or equal to"
