iOS从当前date起一个月。

我试图从当前的date得到一个月。

下面是我所拥有的，它正在返回： 4027-09-24 16:59:00 +0000 。 currentDate是正确的。 这是怎么回事？

 // Get todays date to set the monthly subscription expiration date NSDate *currentDate = [NSDate date]; NSLog(@"Current Date = %@", currentDate); NSDateComponents *dateComponents = [[NSCalendar currentCalendar] components:NSMonthCalendarUnit | NSDayCalendarUnit | NSYearCalendarUnit fromDate:currentDate]; dateComponents.month = dateComponents.month + 1; NSDate *currentDatePlus1Month = [[NSCalendar currentCalendar] dateByAddingComponents:dateComponents toDate:currentDate options:0]; NSLog(@"Date = %@", currentDatePlus1Month); 

Answer 1

试试这个：

 // Get todays date to set the monthly subscription expiration date NSDate *currentDate = [NSDate date]; NSLog(@"Current Date = %@", currentDate); NSDateComponents *dateComponents = [NSDateComponents new]; dateComponents.month = 1; NSDate *currentDatePlus1Month = [[NSCalendar currentCalendar] dateByAddingComponents:dateComponents toDate:currentDate options:0]; NSLog(@"Date = %@", currentDatePlus1Month); 

Answer 2

 NSDate *currentDate = [NSDate date]; NSCalendar* calendar = [NSCalendar currentCalendar]; NSDateComponents* components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit fromDate:currentDate]; // Get necessary date components [components month]; //gives you month [components day]; //gives you day [components year]; //gives you year
