Answer 1

With iOS 8 and OS X 10.9 you can add NSCalendarUnits using NSCalendar:

Objective-C

NSCalendar *cal = [NSCalendar currentCalendar];
NSDate *someDate = [cal dateByAddingUnit:NSCalendarUnitMonth value:1 toDate:[NSDate date] options:0];

Swift 3

let date = Calendar.current.date(byAdding: .month, value: 1, to: Date())

Swift 2

let cal = NSCalendar.currentCalendar()
let date = cal.dateByAddingUnit(.Month, value: 1, toDate: NSDate(), options: [])
