title: uilabel tail truncation
body: <p>Im working on an ios app using objective c and i have an issue with uilabel that i could use some help with. Basically i have a label that can change size to fit the text that it will display but it has a max height that it can possible be. the label itself has a fixed width at all times. i have turned on UILineBreakModeWordWrap and UILineBreakModeTailTruncation to make the text fit and truncate but this causes the text to truncate the tail too early when it has only 1 word left to place. rather then moving it onto the next line when there is still room it just truncates it.</p>
  
  <pre><code>self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, fixedWidth, 0);
  self.lineBreakMode = UILineBreakModeWordWrap | UILineBreakModeTailTruncation;
  self.numberOfLines = 0;
  [self sizeToFit];
  </code></pre>
  
  <p>is there anyway of finding when the uilabel is actually truncating the text so i can then check the label height and add to it if there is still room ? I tried always adding an extra line to the height when there is room and this avoids the early truncation but then im left with inconsistent sizing of the over all label. any ideas on this would be great thanks</p>
