试试这个..

NSDateFormatter *dateFormatter = [NSDateFormatter new]; 
    [dateFormatter setDateFormat:@"dd/MM/yyyy HH:mm"]; 

    //Create the date assuming the given string is in GMT 
    dateFormatter.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:0]; 

    //Create a date string in the local timezone 
    dateFormatter.timeZone = [NSTimeZone timeZoneForSecondsFromGMT:[NSTimeZone localTimeZone].secondsFromGMT]; 
    NSString *localDateString = [dateFormatter stringFromDate:[NSDate date]]; 
    NSLog(@"date = %@", localDateString); 

，如果你想具体的时区日期，那么请参阅下面的代码..

NSDate *myDate = [NSDate date]; 
    NSDateFormatter *dateFormatter1 = [[NSDateFormatter alloc] init]; 
    [dateFormatter1 setDateStyle:NSDateFormatterLongStyle]; 
    [dateFormatter1 setTimeStyle:NSDateFormatterLongStyle]; 
    [dateFormatter1 setDateFormat:@"dd/MM/yyy hh:mm a"]; 

NSTimeZone *timeZone = [NSTimeZone timeZoneWithName: @"Asia/Calcutta"]; 
[dateFormatter1 setTimeZone:timeZone]; 

NSString *dateString = [dateFormatter1 stringFromDate: myDate]; 
NSLog(@"%@", dateString);
