如何将系统毫秒转换为objective-c中的Date

Question

我从Web服务获取日期，如/ Date（1326067200000）/，如何将其转换为DD.MM.YYYY之类的日期？

Answer 1

You can use

    NSString *actDate = @"/Date(1326067200000)/";
    NSString *nDate = [[[[actDate componentsSeparatedByString:@"("] objectAtIndex:1] componentsSeparatedByString:@")"] objectAtIndex:0];
    NSDate *date = [NSDate dateWithTimeIntervalSince1970:([nDate doubleValue] / 1000)];

In date you will get the actual date. Further you can format it in "MM/dd/yyyy" format by using

    NSDateFormatter *dtfrm = [[NSDateFormatter alloc] init];
    [dtfrm setDateFormat:@"MM/dd/yyyy"];
    nDate = [dtfrm stringFromDate:date];

In nDate you will get your desired date in a formatted way.

Answer 2

//Use of Function
textFiled.text = [self displayDate:[[NSString stringWithFormat:@"%@",[[[AllKeys valueForKey:@"Date"] componentsSeparatedByString:@"\"]]]]  


// Millisecond to Date conversion
- (NSDate *)displayDate:(double)unixMilliseconds {

    NSDate *date = [NSDate dateWithTimeIntervalSince1970:unixMilliseconds / 1000.];
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

    [dateFormatter setDateStyle:NSDateFormatterShortStyle];
    [dateFormatter setTimeStyle:NSDateFormatterShortStyle];
    [dateFormatter setLocale:[NSLocale currentLocale]];

    NSLog(@"The date is %@", [dateFormatter stringFromDate:date]);
  //  NSDate *returnValue = [dateFormatter stringFromDate:date];
    return date;
}

Answer 3

Use NSDate's initWithTimeIntervalSinceReferenceDate: (assuming your value uses the first instant of 1 January 2001, GMT as reference date) to get a NSDate instance representing your timestamp.

To get a formatted string representation, you can use the class NSDateFormatter .

Answer 4

Try this...

NSDate *date=[[NSDate alloc] initWithTimeIntervalSinceReferenceDate:gettingdate];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc]init];
[dateFormat setDateFormat:@"dd-MM-yyyy HH:mm:SS"];
NSString *newdate = [dateFormat stringFromDate:date];
