Whitespace for UITextView

There are different margins/paddings between UILabel and UITextView
Example:

If you wanted to remove the whitespace for UITextView so you can have what you expect from autolayout, do this.

self.commentTextView.textContainerInset = UIEdgeInsetsZero

self.commentTextView.textContainer.lineFragmentPadding = 0

tab bar title inherits navbar title

I've always conveniently used self.title = "New Title" to update my navigation bar's title

However, I recently noticed that will affect the tabbar title as well, to prevent the tabbar from inheriting the navbar's title, use

self.navigationItem.title  = "My New Title"

to prevent changing the tab bar item's title as well
