Scrolling not working on progressBar view while progress is running.

I have added MBCircularProgressBar view inside scrollView. When progress view is in the running state, I can't able to scroll scrollView by swiping up/down on progress view only. Swiping on views other than progress view working well even in running progress view.
Also, when progress view is not running, I can able to scroll scrollView properly while swiping up/down on progress view.
