[buguibu]

I'm using the dayStyle "CALDayCollectionViewCellDayUIStyleIOS7" and the year of the month isn't shown, what i have to do for display the agenda as in the center example of the image https://github.com/leverdeterre/CalendarIOS7/raw/master/Screenshots/Calendar.png ?

Right, i'have change a method in the CALAgendaViewController.
monthAtIndexPath: selector return a string to configure the header section but the formater has change. The old code is still there (in comment), but a better approach would be to set an option on the controller to configure month or month + year
