Question

我有一个字符串格式的日期，就像30-11-2012一样。我希望它旁边的日期再次为01-12-2012字符串格式。有没有办法得到它？

Answer 1

您应该使用NSCalendar以获得最佳兼容性

NSDate *today = [NSDate dateWithNaturalLanguageString:@"2011-11-30"];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *dayComponent = [NSDateComponents new];
dayComponent.day = 1;

today = [calendar dateByAddingComponents:dayComponent toDate:today options:0];
//2011-12-01 12:00:00 +0000

我得到了一个我忘了名字的答案，我正准备接受他/她的答案，但是当我点击接受答案时，它告诉我，帖子已被删除。

下面给出了匿名人士给出的答案

NSString *dateString = @"22-11-2012";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
dateFromString = [dateFormatter dateFromString:dateString];


NSDateComponents *components= [[NSDateComponents alloc] init];
[components setDay:1];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDate *dateIncremented= [calendar dateByAddingComponents:components toDate:dateFromString options:0];

NSDateFormatter *myDateFormatter = [[NSDateFormatter alloc] init];
[myDateFormatter setDateFormat:@"dd-MM-yyyy"];
NSString *stringFromDate = [myDateFormatter stringFromDate:dateIncremented];
NSLog(@"%@", stringFromDate);

最后我真的要感谢那个匿名的人，我知道这并不是那么棘手，但这对我帮助很大。再次感谢Anonymous Helper。

swift 3.0

var components = DateComponents()
components.day = 1
let now = Date()
let futureDate = Calendar.current.date(byAdding: components, to: now, wrappingComponents: false)

// now = 2017-03-22 futureDate = 2017-03-23

在iOS中将日期转换为第二天的日期
