QRコードvCardを読み取り、QRコードvCardの連絡先情報の詳細を表示するために使用される1つの簡単なアプリケーションを開発しています。次のように、vCard をスキャンして、連絡先に関する詳細を取得できます。
BEGIN:VCARD
VERSION:2.1
N:XX;XXXXXXXX
FN:XXXXXXXXX XX
TEL;WORK;VOICE:91999999999
EMAIL;WORK;INTERNET:sac@gmail.com
END:VCARD
しかし、その中の各要素を解析する必要があります。詳細を解析する方法と、解析する方法は何ですか?
この質問をするのはかなり久しぶりです。しかし、今すぐ回答することは、このページに移動した人にも役立つ可能性があります。以下の方法を参照して、VCF データを解析できます。
NSString *str = [NSString stringWithString:response.vcfString];

ドキュメントはこのメソッドを指しています：
- (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];
}
}
私は最初にそれが返すものを見て、おそらく追加のデータのために辞書をループしてみてください
QRコードのエンコーダーが使えます
