Approximately 8 months ago, I got an inspiration to creating something that can boom and show menu, which I named it Boom-Menu-Button, BMB. But at that time, I just a fresh-man in Android, knowing little about designing. The codes I wrote serveral months ago are ugly and performed low-efficient. Between months, I always think about BMB and try to write a better design pattern for implements of BMB. My first try is BMB-iOS, which contains more family characteristics, for instance, buttons-alignment, text-inside/outside-button.
