【中文标题】NFC iOS 13 读写故障【英文标题】:NFC iOS 13 read/write trouble 【发布时间】:2019-06-28 11:49:20 【问题描述】:我阅读了有关 CoreNFC 的所有文档,观看了 WWDC 2019 中有关读写标签的所有视频,但我没有找到任何关于我的问题的信息。 我需要用一些数据写标签,以便在办公室打开门/窗。我使用读取的 NFC 标签在 swift 上创建了一个简单的项目,但是当我将手机放在 USB 阅读器上时,我的日志中出现了下一个问题:

我试图找到一些关于 decodeObjectForKey: class "NFFieldNotification" 但在谷歌页面上没有任何信息。也许有人可以帮助我?或者,ios 13 beta 2 或 xCode 11 beta 2 只是这么原始的产品?假设这个问题对未来有帮助......
【问题讨论】:
这里有一些有用的信息github.com/underwindfall/NFCandroid/issues/1。 我知道,我已经阅读了这篇文章,但没有一个解决方案 感谢您的留言,我会在正常发布后尝试) 有人有NFC同屏读写的解决方案吗? 仍然需要解决方案。 【参考方案1】:我遇到了同样的问题并通过添加解决了它
CoreNFC.framework
在
xyz.xcodeproj -> 构建阶段 -> 将二进制文件与库链接
(xyz.xcodeproj 是我的项目根文件)
