iOS 8 – 获取当前date为DD / MM / YYYY

有人可以给我一些代码，我怎么得到的date？

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在一周内得到明天的date，等等…

谢谢 ：）

Answer 1

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

 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，你可以使用NSDateFormatter ：

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

Answer 2

  NSDate *todayDate = [NSDate date]; //Get todays date NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; // here we create NSDateFormatter object for change the Format of date. [dateFormatter setDateFormat:@"dd-MM-yyyy"]; //Here we can set the format which we need NSString *convertedDateString = [dateFormatter stringFromDate:todayDate];// Here convert date in NSString NSLog("Today formatted date is %@",convertedDateString);

Answer 3

试试这个，设置不同的组件单元：

  NSDate *today = [NSDate date]; NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents * components = [gregorian components:(NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit) fromDate:today]; NSInteger day = [components day]; NSInteger month = [components month]; NSInteger year = [components year]; 

如果你想得到其他的日子，使用这个链接日历得到其他的一天

Answer 4

你可以得到这样的

 let dateFormatter = DateFormatter() dateFormatter.dateFormat = "dd/MM/yyyy" let dateString = dateFormatter.string(from:Date()) print(dateString)
