objective c - How to add , > and < into text in UITextView? -

My app's string & amp; Nbsp ;, & amp; Gt; And & amp; Lt; In the text in UITextView we can change the string to the right place. We know that the UITextView string will change & amp; Nbsp; In space, & amp; Gt; To & gt; And & amp; Lt; From & lt;. What should we do if UITextView do not convert it to that character or how to add that string to UITextView?

First thanks. Regards.

 Or you can use UIWebView instead of UITextView
