ios - 如何获得年份序列，因为我只获得月份序列

Question

我使用以下代码获得了月份序列

NSDate *aDate = [NSDate dateWithTimeInterval:row*30*24*60*60  sinceDate:self.earliestPresentedDate];

    NSDateComponents *components = [self.calendar components:(NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit) fromDate:[NSDate date]];
    NSDate *today = [self.calendar dateFromComponents:components];
    components = [self.calendar components:(NSEraCalendarUnit|NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit) fromDate:aDate];
    NSDate *otherDate = [self.calendar dateFromComponents:components];

    if ([today isEqualToDate:otherDate]) {

    } else {
        NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
        formatter.locale = [NSLocale currentLocale];
        formatter.dateFormat = @"MMM ";

        [lblDate setText:[formatter stringFromDate:aDate]];
    }

我想得到年度序列如何得到...请给出解决方案

Answer 1

制作一个函数，给出下一年的日期，如下所示，

NSDateComponents *dayComponent = [[NSDateComponents alloc] init];
    dayComponent.year = +1;

    NSCalendar *theCalendar = [NSCalendar currentCalendar];
    NSDate *newDate = [theCalendar dateByAddingComponents:dayComponent toDate:[NSDate date] options:0];

    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    formatter.locale = [NSLocale currentLocale];
    formatter.dateFormat = @"yyyy";
    NSString *strDate = [formatter stringFromDate:newDate];

    NSLog(@"%@",strDate);

在您的标签中设置此日期。

上面我传递了当前日期，所以我将得到年份:2016。
