NSCalendar月份范围

Question

这段代码

NSDateComponents *component = [[NSDateComponents alloc] init];
NSCalendar       *gregorian = [[NSCalendar alloc]   initWithCalendarIdentifier:NSGregorianCalendar];
[component setMonth:1];
[component setYear:2013];
[component setDay:1];
currentMonth = [gregorian dateFromComponents:component];
NSLog(@"Date in MonthView %@ ",currentMonth);

给我以下日期

Date in MonthView 2012-12-31 23:00:00 +0000

为什么？月份范围应该从0到11？

Answer 1

不,几个月从1到12.这可能是因为您的设备/ PC的时区.设置timezine,你应该有你期望的日期

[component setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"GMT"]]
