I have make this decoder for ios app
我已经为 ios 应用程序制作了这个解码器
here the code :
这里的代码：

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);
The barcodestring contains the data which are scanned from pdf 417.
条形码字符串包含从 pdf 417 扫描的数据。
