Question

尝试从当月开始接收当年的下一个十二个月。下面是我正在尝试的代码，但它是从下个月开始挑选的，所以我修改了它，但现在它显示了2014年的当月和2013年的其他月份。

 NSDateFormatter  *dateFormatter   = [[NSDateFormatter alloc] init];
NSDate           *today           = [NSDate date];
NSCalendar       *currentCalendar = [NSCalendar currentCalendar];

NSDateComponents *monthComponents = [currentCalendar components:NSMonthCalendarUnit fromDate:today];
int currentMonth = [monthComponents month];

NSDateComponents *yearComponents  = [currentCalendar components:NSYearCalendarUnit  fromDate:today];
int currentYear  = [yearComponents year];
int nextYear     = currentYear + 1;

int months  = 1;
int year;
for(int m = currentMonth-1; months < 12; m++){

int nextMonth = m % 12;

if(nextMonth < currentMonth){
    year = nextYear;
} else {
    year = currentYear;
}

NSLog(@"%@ %i",[[dateFormatter monthSymbols] objectAtIndex: nextMonth],year);

months++;
}
