如何使用NSDateFormatter将NSString转换为NSDate？

Question

I getting the date from the webservice like "2012-07-03 07:26:48". I have saved in NSString after parsing from webservice. While convert the NSString to NSDate used below code,

    NSDateFormatter *dateFormatter1 = [[NSDateFormatter alloc] init];
    [dateFormatter1 setDateFormat:@"yyyy-MM-dd hh:mm:ss"];

    NSString *dateStr = @"2012-07-03 07:26:48";
    NSDate *date = [dateFormatter1 dateFromString:dateStr];
    NSLog(@"Date : %@", date);
   The NSLog value is "2012-07-03 01:56:48 +0000";

The NSLog value is "2012-07-03 01:56:48 +0000"; I don't know why the time has changed. Can anyone please help me to do this?

Answer 1

You need to put timezone as:

theDateFormatter.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:0];

Because it is considering GMT time format.

Answer 2

您必须设置NSDateFormatter的时区。

Answer 3

默认情况下，日期以utc格式保存，同时将字符串转换为nsdate ...您可以将日期中的原始时间作为字符串...如果要更改时区，请使用dateformatter进行更改..否则不要更改
