I wrote a category over UITextView:

- (CGSize)intrinsicContentSize {
    return self.contentSize;
}

- (void)setContentSize:(CGSize)contentSize {
    [super setContentSize:contentSize];
    [self invalidateIntrinsicContentSize];
}

When UIKit sets its contentSize, UITextView adjusts its intrinsic content size. That plays nicely with autolayout.
