我有字符串 - 12月13日,10:00 AM IST
如何将此字符串转换为任何人建议的日期?
我创建了这个日期格式化程序但是得到了null -
NSDateFormatter *userTimeFormatter = [[NSDateFormatter alloc] init];
[userTimeFormatter setDateStyle:NSDateFormatterMediumStyle];
[userTimeFormatter setTimeStyle:NSDateFormatterShortStyle];
userTimeFormatter.doesRelativeDateFormatting = YES;
[userTimeFormatter setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];
答案 0 :(得分:2)
NSDateFormatter *userTimeFormatter = [[NSDateFormatter alloc] init];
NSString *dateString = @"Dec 13, 10:00 AM IST";
NSTimeZone *timeZone = [NSTimeZone timeZoneWithAbbreviation:@"IST"];
[userTimeFormatter setTimeZone:timeZone];
dateString = [dateString stringByReplacingOccurrencesOfString:@" IST" withString:@""];
[userTimeFormatter setDateFormat:@"MMM d, hh:mm a"];
NSDate *date = [userTimeFormatter dateFromString:dateString];
NSLog(@"india date : %@", date);
这将为您提供IST TimeZone NSDate,从此日期开始您可以转换为系统时区:
[userTimeFormatter setTimeZone:[NSTimeZone systemTimeZone]];
NSDate *myDate = [userTimeFormatter dateFromString:dateString];
NSLog(@"my date : %@", myDate);
输出:
india date : 2000-12-13 04:30:00 +0000
my date : 2000-12-13 06:00:00 +0000
