Question

日期＆amp;时间格式为“yyyyMMddHHmmss”。我无法将此时间转换为EST时区。我遵循一些教程，但我没有得到正确的结果。如果有任何API进行此转换，请告诉我。

Answer 1

您应该按照以下方式进行：

1）首先，创建一个NSDateFormatter来获取NSDate

NSDateFormatter *serverFormatter = [[NSDateFormatter alloc] init];
[serverFormatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"GMT"]];
[serverFormatter setDateFormat:@"'at 'HH:mm' of 'dd/MM/yyyy"];

2）将字符串（将其定义为theString）转换为NSDate：

NSDate *theDate = [serverFormatter dateFromString:theString];

3）创建一个NSDateFormatter以将theDate转换为用户：

NSDateFormatter *userFormatter = [[NSDateFormatter alloc] init];
[userFormatter setDateFormat:@"HH:mm dd/MM/yyyy"];
[userFormatter setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"EST"]];

3）从userFormatter获取字符串：

 NSString *dateConverted = [userFormatter stringFromDate:theDate];

希望这可以帮助你!!!

    NSString *startTime = @"20140508063630";
    NSDateFormatter *workingHoursFormatter = [[NSDateFormatter alloc] init]; 
    NSTimeZone *timeZone = [NSTimeZone timeZoneWithName:@"EST"];
    [workingHoursFormatter setTimeZone:timeZone];
    [workingHoursFormatter setDateFormat:@"yyyyMMddHHmmss"];
    NSDate *openingTime = [workingHoursFormatter dateFromString:startTime];

试试吧。在这里工作。

NSDateFormatter *inputDateFormat = [[NSDateFormatter alloc] init];
[inputDateFormat setDateFormat:@"yyyyMMddHHmmss"];
[inputDateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];

NSDateFormatter *outputDateFormat = [[NSDateFormatter alloc] init];
[outputDateFormat setDateFormat:@"yyyyMMddHHmmss"];
[inputDateFormat setTimeZone:[NSTimeZone timeZoneWithName:@"EST"]];

NSString *outputDate = [outputDateFormat stringFromDate:[inputDateFormat dateFromString:@"20140508063630"]];
NSLog(@"%@",outputDate);
