In Xcode 6.1 for iOS 7/8, I was able to get this to work by just setting preferredMaxLayoutWidth in a setter method that's called on my view to display the text for the label.

- (void)setTeachPieceText:(NSString *)teachPieceText {
      self.teachPieceLabel.text = teachPieceText;
      [self.teachPieceLabel setPreferredMaxLayoutWidth:[self.teachPieceLabel bounds].size.width];
}
