CoreNFC无法在iOS中读取UID [英] CoreNFC not reading UID in iOS

问题描述

我已经在iOS中使用CoreNFC尝试了一个示例，但是它无法读取制造商的NFC标签的UID，而是期望标签中的消息内容并且只能读取，是否有任何方法可以使CoreNFC读取NFC标签的内容UID?

I have tried a sample with CoreNFC in iOS, but it fails to read the manufacturer's UID of the NFC Tag, instead it expects message content from the Tag and reads only that, Is there any way to make CoreNFC read the NFC Tag's UID?

推荐答案

iOS 13上对CoreNFC的更新意味着您现在可以使用兼容的iPhone读取大多数UID.这样做:请参见 https://stackoverflow.com/a/57993069/3959708

Updates to CoreNFC on iOS 13 mean you can now read most UIDs with compatible iPhones. To do so: see https://stackoverflow.com/a/57993069/3959708

可以读取标签的UID，但由于API是私有的，因此无法将其提交到App Store.

It is possible to read the UID of a tag, but it will not be able to be submitted to the App Store because the API is private.

 - (void) readerSession:(nonnull NFCNDEFReaderSession *)session didDetectNDEFs:(nonnull NSArray<NFCNDEFMessage *> *)messages {

  NSArray *foundTags = [session valueForKey:@"_foundTags"];
  NSObject *tag = foundTags[0];
  NSData *uid = [tag valueForKey:@"_tagID"];
}
