我有一个Android应用程序，我正在扫描PDF417条形码图像。扫描条形码后，我得到的结果如下。

我想从上面的字符串获得详细信息，如FirstName, LastName, City, Address等。谁能告诉我如何得到详细信息?
谢谢。
请参见下面的链接并生成解析器以提取驾驶执照信息
http://www.dol.wa.gov/external/docs/barcodeCalibration-EDLEID.pdf我已经使这个解码器为ios应用程序
这里的代码:
NSString *消息= barcode.barcodeString;
NSMutableArray *arrFixedData=[[NSMutableArray alloc]initWithObjects:@"DCS",@"DCT",@"DCU",@"DAG",@"DAI",@"DAJ",@"DAK",@"DCG",@"DAQ",@"DCA",@"DCB",@"DCD",@"DCF",@"DCH",@"DBA",@"DBB",@"DBC",@"DBD",@"DAU",@"DCE",@"DAY",@"ZWA",@"ZWB",@"ZWC",@"ZWD",@"ZWE",@"ZWF", nil];
NSMutableArray *arrDriverData=[[NSMutableArray alloc]initWithObjects:@"Customer Family Name",@"Customer Given Name",@"Name Suffix",@"Street Address 1",@"City",@"Jurisdction Code",@"Postal Code",@"Country Identification",@"Customer Id Number",@"Class",@"Restrictions",@"Endorsements",@"Document Discriminator",@"Vehicle Code",@"Expiration Date",@"Date Of Birth",@"Sex",@"Issue Date",@"Height",@"Weight",@"Eye Color",@"Control Number",@"Endorsements",@"Transaction Types",@"Under 18 Until",@"Under 21 Until",@"Revision Date", nil];
NSMutableDictionary *dict=[[NSMutableDictionary alloc]init];
for (int i=0; i<[arrFixedData count]; i++)
{
NSRange range = [message rangeOfString: [arrFixedData objectAtIndex:i] options: NSCaseInsensitiveSearch];
NSLog(@"found: %@", (range.location != NSNotFound) ? @"Yes" : @"No");
if (range.location != NSNotFound)
{
NSString *temp=[message substringFromIndex:range.location+range.length];
NSRange end = [temp rangeOfString:@"n"];
if (end.location != NSNotFound)
{
temp = [temp substringToIndex:end.location];
temp =[temp stringByReplacingOccurrencesOfString:@"n" withString:@""];
temp=[temp stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
NSLog(@"temp data : %@",temp);
[dict setObject:temp forKey:[arrDriverData objectAtIndex:i]];
}
}
NSLog(@"Dictionary : %@",dict);
条形码字符串包含从pdf 417扫描的数据。
谢谢
