broken in iOS7: multiplies tokens while switching to textView

[zxcat]

Steps to reproduce:

1. Run example project in iOS7
2. type something, which is not found in demo names. For example "zz"
3. Now textView is visible, tap on it
4. tap on textField again
5. repeat steps 3-4 several times
6. See the Bug

Yup, I'm seeing it. Dunno why yet.

UITextView and UITextField changed in iOS7. I've found (in my other project), they can send more messages to delegate comparing with iOS6 and earlier.
E.g. for UITextView I receiving -textViewDidChange: and -textViewDidChangeSelection in places where they were not sent earlier.
Maybe this is somehow related.

I agree, for some reason the text isn't tokenized when the field loses focus, as it should.

More fun, related with issue:
(+) button shows modal view controller in my code.

1. enter some text, to make search list appear under field
2. tap (+) to show VC
   After return from modal VC, field will contain 8x tokens (or even more)

Instead of step 2 you can pop current VC (go back with navigation bar). In this case keyboard will be visible in that previous VC.

One problem is here:

0x0009f23a in -[TITokenField addToken:] at Pods/TITokenField/TITokenField.m:608
0x0009f0bd in -[TITokenField addTokenWithTitle:representedObject:] at Pods/TITokenField/TITokenField.m:592
0x0009ef55 in -[TITokenField addTokenWithTitle:] at Pods/TITokenField/TITokenField.m:585
0x0009feac in __28-[TITokenField tokenizeText]_block_invoke at Pods/TITokenField/TITokenField.m:685
0x032b405d in __53-[__NSArrayI enumerateObjectsWithOptions:usingBlock:]_block_invoke ()
0x032b3f92 in -[__NSArrayI enumerateObjectsWithOptions:usingBlock:] ()
0x032310a5 in -[NSArray enumerateObjectsUsingBlock:] ()
0x0009fd07 in -[TITokenField tokenizeText] at Pods/TITokenField/TITokenField.m:684
0x0009e52a in -[TITokenField didEndEditing] at Pods/TITokenField/TITokenField.m:531

After losing focus -[TITokenField didEndEditing] is called. But at some point -[TITokenField addToken:] being executed. It runs [self becomeFirstResponder] and cause some kind of loop.

Great stuff, this is all really helpful. Thanks.
