Get UITextView dynamic height with auto layout after setting text

Question

I have a UITextView not scrollable with auto layout set by interface builder, and the text increase or decrease dynamically with no problem, but i want know what is the new UITextView height after setting text, i'm trying to do this:

NSLog(@"text before: %.2f",self.myText.frame.size.height); [self.myText setText:self.string]; NSLog(@"text after: %.2f",self.myText.frame.size.height); 

this is the result:

text before: 47.50 text after: 47.50 

the text is increased in the view when i run it, but the size is the same, how i can get the real height after setting text?

Answer 1

All you have to do is:

• set up all your constraints except the height one AND
• set textView's scrollEnabled property to NO

The last part is what does the trick.

Your text view will size automatically depending on its text value.

Answer 2

If you prefer to do it all by auto layout:

In Size Inspector:

1. Set Content Compression Resistance Priority Vertical to 1000.

2. Lower the priority of constraint height for your UITextView. Just make it less than 1000.

In Attributes Inspector:

1. Uncheck Scrolling Enabled.
