title: UITextViewDelegate behaviour when backspace key is HELD Down
body: <p>I've run into a problem where iOS is giving my UITextViewDelegate incorrect information when the delete key is held on the keyboard.</p>
  
  <p>When the user <strong>HOLDS</strong> the delete key on a UITextView on an iPad the UITextView will begin to delete entire words instead of individual characters the longer it is held down (note: this does not occur in the simulator).</p>
  
  <p>When this happens, the UITextView delegate method:</p>
  
  <pre><code>- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
  </code></pre>
  
  <p>Gets called with a range consisting of the correct cursor location, but a length of 1. This is incorrect as the UITextView is now deleting entire words, not single letters. The following code, for example, will print only a single space.</p>
  
  <pre><code>[textView substringWithRange:range]
  string contains " "
  </code></pre>
  
  <p>Despite the UITextView removing a whole word. The replacement text is correctly given as the empty string. Does any one know of a solution or workaround to this problem?</p>
