如何向 NSDate 添加 1 天？

基本上就如标题所说。我想知道如何添加 1 天NSDate.

所以如果是：

21st February 2011

它将变成：

22nd February 2011

或者如果是：

31st December 2011

它将变成：

1st January 2012.

斯威夫特 5.0：

var dayComponent    = DateComponents()
dayComponent.day    = 1 // For removing one day (yesterday): -1
let theCalendar     = Calendar.current
let nextDate        = theCalendar.date(byAdding: dayComponent, to: Date())
print("nextDate : \(nextDate)")

目标C：

NSDateComponents *dayComponent = [[NSDateComponents alloc] init];
dayComponent.day = 1;

NSCalendar *theCalendar = [NSCalendar currentCalendar];
NSDate *nextDate = [theCalendar dateByAddingComponents:dayComponent toDate:[NSDate date] options:0];

NSLog(@"nextDate: %@ ...", nextDate);

这应该是不言自明的。
