Question

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 pri

I entered rdar against this problem, but did find a work around. Essentially you have to programmatically replace the "stuck" control with a new one. The easiest thing to do is to archive the existing control in viewDidLoad then unarchive as needed:

// do in viewDidLoad
self.passwordMemberArchive = [NSMutableData data];
NSKeyedArchiver *ka = [[NSKeyedArchiver alloc]       initForWritingWithMutableData:passwordMemberArchive];
[ka encodeObject:password];
[ka finishEncoding];
[ka release];


    // In the action method when you get the UISwitch action message ---
// when your switch changes state
if(isOn) {
    NSString *text = [NSString stringWithString:password.text];
    NSKeyedUnarchiver *kua = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
    UITextField *tf = [kua decodeObject];
    [kua finishDecoding];
    [kua release];
    tf.inputAccessoryView = textField.inputAccessoryView;
    tf.frame = textField.frame;

    BOOL isFirstResponder = [textField isFirstResponder];
    [scrollView insertSubview:tf aboveSubview:textField];
    if(isFirstResponder) {
        [tf becomeFirstResponder];
    }

    [textField removeFromSuperview];
    self.password = tf;

    if([text length]) {
        if(isFirstResponder) {
            // http://stackoverflow.com/questions/1317929/insert-string-at-cursor-position-of-uitextfield
            // Get a reference to the system pasteboard
            UIPasteboard* lPasteBoard = [UIPasteboard generalPasteboard];
            // Save the current pasteboard contents so we can restore them later
            NSArray* lPasteBoardItems = [lPasteBoard.items copy];
            // Update the system pasteboard with my string
            lPasteBoard.string = text;
            // Paste the pasteboard contents at current cursor location
            [tf paste:self];
            // Restore original pasteboard contents
            lPasteBoard.items = lPasteBoardItems;
            [lPasteBoardItems release];
        } else {
            tf.text = text;
        }
    }
} else {
    textField.secureTextEntry = NO;
}
