BindMemory 迁移 Swfit 3

Question

如何将此代码迁移到 Swift3？

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

我遇到错误

'bytes' is unavailable: use withUnsafeBytes instead

Answer 1

keyData 是 Data 对象的类型并且没有 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)
