iOS 8 - 获取当前日期为DD / MM / YYYY [英] iOS 8 - get current date as DD/MM/YYYY

问题描述

  NSDateComponents * components = [[NSCalendarcurrentCalendar]组件：NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYearfromDate：[NSDatedate]]; 
 
 NSString * day = [components day]; 
 NSString * week = [组件月]; 
 NSString * year = [components year]; 
 
 NSString * date = [NSString stringWithFormat：@％@。％@。％@，日，周，年]; 
  

^^我的代码不工作：S

是否有一种方式可以在1周内获得明天的日期，等等...

感谢：）

解决方案

您可以使用代码检索数字组件的变体，使用 NSCalendar 组件方法：

  NSDateComponents * components = [[NSCalendar currentCalendar] ：NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate：[NSDate date]]; 
 
 NSInteger day = [components day]; 
 NSInteger月= [组件月]; 
 NSInteger year = [components year]; 
 
 NSString * string = [NSString stringWithFormat：@％ld。％ld。％ld，（long）day，（long）month，（long）year] 
  

注意，这是组件，而不是code>组件。

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]]; 
  

Can anybody give me some code how I get the 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];

^^ my code is not working :S

And is there a way that I can get the date of tomorrow, in 1 week and so on...

Thanks :)

解决方案

You can either use a variation of your code that retrieves the numeric components using NSCalendar with the components method:

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];

Note, that's components, not component.

Or, better, you can use NSDateFormatter:

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