objective-c - 如何为 NSDate 添加 1 天？

Question

基本上，正如标题所说。我想知道如何将 1 天添加到 NSDate。

如果是这样的话:

21st February 2011

它会变成:

22nd February 2011

如果是的话:

31st December 2011

它会变成:

1st January 2012.

Answer 1

Swift 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)")

Objective-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。
