IOS dynamically defines heights based on text content for TextView

Solution:

1. Define a TextView and set the constraints of the TextView in the storyboard.

2. Define the height of the constraint in the header file: (direct drag)

@property (Weak, nonatomic) Iboutlet nslayoutconstraint *textviewheightconstraint;

3. After loading the content for TextView in the implementation file, get the text height and assign a value to the constraint:

    Cgsize sizethatshouldfitthecontent = [Self.shippingaddresstextview sizethatfits: Self.shippingAddressTextView.frame.size];    Self.textviewHeightConstraint.constant = Sizethatshouldfitthecontent.height;
