Resizing UITextView in custom UITableViewCell

Question

I have a custom UITableViewCell and I\'m trying to resize the UITextView inside it based on the content size. I\'m on iOS7 and using Autolayout.

Answer 1

I think you might have too many constraints for the text view. I can't be sure of this because it's difficult to communicate information about constraints that are built in IB.

Your text view only needs two constraints, one for each axis, in order to be fully constrained. One constraint should position the text view horizontally, the other vertically. The text view's intrinsic content size will be used by the Auto Layout system to automatically generate size constraints for the text view.

I think some of the constraints you have in place now are preventing resizing of the text view. This happens because, by default, constraints you create yourself are required (priority 1000). The automatically-generated sizing constraints, on the other hand, have a lower priority and will be overruled by any conflicting constraints that are required.

Note: just because the text view only needs two constraints to be fully constrained doesn't mean that you can't have more constraints. A table cell with 4 labels, 3 image views, and 1 text view is a complex layout, so you will most likely constrain other UI objects relative to the text view, rather than the superview.
