BindMemory迁移Swfit 3

Question

如何将此代码迁移到Swift 3？

let keyBytes = keyData.bytes.bindMemory(to: Void.self, capacity: keyData.count)

我收到以下错误

  

'bytes'不可用：改为使用withUnsafeBytes

Answer 1

keyData是Data对象的类型，没有属性bytes，将keyData转换为NSData，然后访问bytes

let keyBytes = NSData(data: keyData).bytes.bindMemory(to: Void.self, capacity: keyData.count)
