Question

有人可以给我一些代码我如何得到约会？

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];

^^我的代码无效：S

有没有办法可以在一周内获得明天的日期等等......

谢谢：）

Answer 1

您可以使用NSCalendar方法使用components来检索数字组件的代码变体：

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];

注意，那是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]];

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

你可以这样做

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

Answer 4

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];

如果您想获得其他日子，请使用此链接 calendar get other day
