在 ios 中将字符串数据“03:12:00 May 06, 2014 MDT”转换为 nsdate“03-05-2014”

Question

我的日期类似于"payment_date" = "03:12:00 May 06, 2014 MDT";。
但我想把这些数据转换成NSDate，比如"06-05-2014"

请帮帮我， 不知道怎么处理..

我从Converting NSString to NSDate (and back again)得到了答案

 __block NSDate *detectedDate;

//Detect.
NSDataDetector *detector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingAllTypes error:nil];
[detector enumerateMatchesInString:t_date
                           options:kNilOptions
                             range:NSMakeRange(0, [t_date length])
                        usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop)
{ detectedDate = result.date;

    NSDate *d=result.date;

}

NSString *str = @"03:12:00 October 06, 2014 MDT";
NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setLocale:[NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"]];
[df setDateStyle:NSDateFormatterLongStyle];

str = [str substringFromIndex:9];
NSDate *date = [df dateFromString:[str substringToIndex:[str length] -3]];
[df setDateFormat:@"dd-MM-YYYY"];
NSLog(@"%@",[df stringFromDate:date]);
