选择星期日，选择下周的日期

Question

您好我使用此代码获取开始日期和结束日期。但是，如果我选择星期天它会在下周继续运行并在下周给我结果。

请通过选择星期日来建议我如何获得适当的结果。

提前谢谢。

NSDate *today = date;
NSLog(@"Today date is %@",today);
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"yyyy-MM-dd"];// you can use your  format.

//Week Start Date

NSDateComponents *components = [gregorian components:NSCalendarUnitWeekday | NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay fromDate:today];

NSInteger dayofweek = [[[NSCalendar currentCalendar] components:NSCalendarUnitWeekday fromDate:today] weekday];// this will give you current day of week

[components setDay:([components day] - ((dayofweek) - 2))];// for beginning of the week.
