This fixes the bug :

- (BOOL)becomeFirstResponder
{
    BOOL ret = YES ;

    ret = [super becomeFirstResponder] ;

    if( ret && ( _setupClearButtonMode == UITextFieldViewModeWhileEditing ) )
        self.rightViewMode = UITextFieldViewModeAlways ;

    return ret ;
}

- (BOOL)resignFirstResponder
{
    BOOL ret = YES ;

    ret = [super resignFirstResponder] ;

    if( ret && ( _setupClearButtonMode == UITextFieldViewModeWhileEditing ) )
        self.rightViewMode = UITextFieldViewModeWhileEditing ;

    return ret ;
}

In your subclass of UITextField with the var _setupClearButtonMode set on init.
