iPhone : How to get each element from QR code vCard?

Question

我正在开发一个简单的应用程序，用于读取QR码vCard并显示QR码vCard中的联系信息的详细信息。我可以扫描 vCard 并获取有关联系人的详细信息，如下所示

BEGIN:VCARD
VERSION:2.1
N:XX;XXXXXXXX
FN:XXXXXXXXX XX
TEL;WORK;VOICE:91999999999
EMAIL;WORK;INTERNET:sac@gmail.com
END:VCARD

但是我需要解析其中的每个元素。具体如何解析，解析方式有哪些？

Answer 1

文档指向此方法:

- (void) imagePickerController: (UIImagePickerController*) reader
 didFinishPickingMediaWithInfo: (NSDictionary*) info
{
    id<NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults];

    ZBarSymbol *symbol = nil;

    for(symbol in results){

        NSString *upcString = symbol.data;

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Scanned UPC" message:[NSString stringWithFormat:@"The UPC read was: %@", upcString] delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok", nil];

        [alert show];

        [reader dismissModalViewControllerAnimated: YES];    
    }    

}

我会首先查看它返回的内容，也许尝试循环字典以获取其他数据
