Answer 3

You can add days to an NSDate by adding a time interval

NSDate* newDate = [date dateWithTimeInterval:3600*24*numberOfDays sinceDate:otherDate];

Although if you want to be really accurate about it, and take into account leap seconds, day light saving times and all this kind of thing you might want to use NSDateComponents as described in the Date and Time Programming Guide and Omtara's link.
