The project have a bug!
When the width of all tokens in one line equals the width of token field, the next input token will overlap the previous token. You can see the screenshots in this website! https://www.dropbox.com/sh/52j8iqllznfctxl/EogXwoNTpb
I'm unable to replicate the issue - what iOS version are you running on?
Replicate the issue: Step 1: Input "123456" four times; Step 2: Touch the Message Text View; Step 3: Touch the Token Field; Step 4: Input some string. If any problem, you can see the screen shot (https://www.dropbox.com/sh/52j8iqllznfctxl/EogXwoNTpb). By the view, thank you for your sharing of the project! It give me a big help!
Oh, yup, I'm seeing it now.
I'll see what I can do :)
