iOS 8 - 获取当前日期为 DD/MM/YYYY

Question

任何人都可以给我一些如何获取日期的代码吗？

NSDateComponents *components = [[NSCalendarcurrentCalendar] component:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYearfromDate:[NSDatedate]]; 

NSString *day = [components day]; 
NSString *week = [components month]; 
NSString *year = [components year]; 

NSString *date = [NSString stringWithFormat:@"%@.%@.%@",day,week,year];

^^ 我的代码不工作:S

有没有一种方法可以让我在 1 周内等等获得明天的日期...

谢谢:)

Answer 1

您可以使用代码的变体，使用 NSCalendar 和 components 方法检索数字组件:

NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:[NSDate date]];

NSInteger day = [components day];
NSInteger month = [components month];
NSInteger year = [components year];

NSString *string = [NSString stringWithFormat:@"%ld.%ld.%ld", (long)day, (long)month, (long)year];

请注意，这是components，而不是component。

或者，更好的是，您可以使用 NSDateFormatter:

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"d.M.yyyy";
NSString *string = [formatter stringFromDate:[NSDate date]];
