title: Why does this break UILabel adjustsFontSizeToFitWidth?
body: <p>iOS 7, Xcode 5</p>
  
  <p>Using a UILabel, this code works (autosizes the text to fit):</p>
  
  <pre><code>self.testLabel.numberOfLines=0;
  self.testLabel.lineBreakMode=NSLineBreakByWordWrapping;
  self.testLabel.adjustsFontSizeToFitWidth=YES;
  self.testLabel.minimumScaleFactor=0.1;
  self.testLabel.textAlignment=NSTextAlignmentCenter;
  [self.testLabel.font fontWithSize:100.0];
  </code></pre>

  <p>But adding the "setFont" line causes it to not scale the font to fit:</p>
  
  <pre><code>[self.testLabel setFont:[UIFont fontWithName:@"Helvetica Neue" size:62.0f]]; //THIS LINE CAUSES THE FONT SCALING TO FAIL
  self.testLabel.numberOfLines=0;
  self.testLabel.lineBreakMode=NSLineBreakByWordWrapping;
  self.testLabel.adjustsFontSizeToFitWidth=YES;
  self.testLabel.minimumScaleFactor=0.1;
  self.testLabel.textAlignment=NSTextAlignmentCenter;
  [self.testLabel.font fontWithSize:100.0];
  </code></pre>

  <p>Does anyone know a fix for this problem?</p>
