Added RDRStickyKeyboardView in UITableViewController.

Perform the following steps:

1, Call [self.contentWrapper showKeyboard]; when enter into UITableViewController;

2, Exit UITableViewController;

3, Enter into UITableViewController again;

4, Enter any letter, RDRStickyKeyboardView Crash.

@datwelk Please help me fix the problem, thanks.

[datwelk]

You should not use RDRStickyKeyboardView inside a UITableViewController.

[datwelk]

The UITableViewController adds zero value compared to UIViewController, because RDRStickyKeyboardView automatically adjusts the contentOffset of the tableview. Plus, the problem with UITableViewController is that its view property equals its tableview property. If you provide RDRStickyKeyboardView with a UITableViewController's tableview, it will add the tableview as a subview to itself, while it already is a subview of the tableview. See line 569 inside RDRStickyKeyboardView.m.

[Sean-Wang]

I'm sorry. I'd like to set the record straight, I use RDRStickyKeyboardView inside a UIViewController, but UIViewController contain UITableView.

    self.contentWrapper = [[RDRStickyKeyboardView alloc] initWithScrollView:self.commentTableView];
    self.contentWrapper.frame = self.view.bounds;
    self.contentWrapper.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth;
    [self.contentWrapper.inputView.rightButton addTarget:self action:@selector(postCommentToServers) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:self.contentWrapper];

[datwelk]

You have an example project demonstrating the crash I can take a look at?

[Sean-Wang]

Modify the RDRStickyKeyboardView's demo according to my project process, it works well.

But, if I delete the code in the RDRStickyKeyboardView.m

NSCAssert(!(CGRectEqualToRect(keyboardFrame, CGRectZero) && self.inputViewKeyboard.superview == nil), nil); 

My project will not crash.
