The above says it all- I have a UITextField set to secure, but want to give users the option to make it not secure (so they can see for sure what they typed if they are in a private area). However, suppose they hit the toggle by mistake, and want to change it back to secure mode? That does not work. I've tried everything - using -1 instead of YES, deleting the text and then putting it back. I'm at a total loss on other ideas. [Entered rdar://9781908]
EDIT: I believe this issue is fixed as of iOS5.
