in the measureHeight Function

[wangjianlewo]

i do not kown why you use __IPHONE_OS_VERSION_MAX_ALLOWED ? when i set baseSDK with ios7.0 in xcode5 ,and run the app int the device of ios6.0 ,it awlays go to sizeThatFits .
code:

• (CGFloat)measureHeight
  {
  NSLog(@"%d",__IPHONE_OS_VERSION_MAX_ALLOWED);
  #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 70000
  return ceilf([self.internalTextView sizeThatFits:self.internalTextView.frame.size].height);
  #else
  return self.internalTextView.contentSize.height;
  #endif
  }
