基本上，正如标题所说.我想知道如何为 NSDate 添加 1 天.

Basically, as the title says. I'm wondering how I could add 1 day to an NSDate.

如果是这样:

21st February 2011

它会变成:

22nd February 2011

或者如果是:

31st December 2011

它会变成:

1st January 2012.

推荐答案

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)")

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.
