【问题描述】：

我想帮忙提取字典的内容：

advertisementData[kCBAdvDataManufacturer]

advertisementData 是 ios 在 BLE 扫描期间发现广告 BLE 服务器时返回的参数之一。

我看到它的类型是AnyObject。当我打印它时，我可以看到包含在 中的第一个字符。

如何提取剩余的字节内容？

【参考方案1】：

您很可能需要转换为字符串

let manufacturerName = advertisementData[kCBAdvDataManufacturer]! as String
println("The manufacturer is \(manufacturerName).")

【参考方案2】：

斯威夫特 3

 let manufactureData = ((advertisementData as NSDictionary).value(forKey: "kCBAdvDataManufacturer")) as? String
 print(manufactureData)
