ios – UnsafePointer不再适用于swift 3

概述在我从 swift 2转换为 swift 3之后,会d出一个错误以显示下面的行 let value = UnsafePointer<UInt32>(array1).pointee ‘init’ is unavailable: use ‘withMemoryRebound(to:capacity:_)’ to temporarily view memory as another layout-com 在我从 swift 2转换为 swift 3之后,会d出一个错误以显示下面的行

let value = UnsafePointer<UInt32>(array1).pointee

‘init’ is unavailable: use ‘withMemoryRebound(to:capacity:_)’ to temporarily vIEw memory as another layout-compatible type.

在swift2中它就像

let value = UnsafePointer<UInt32>(array1).memory

有人可以解释一下吗？
对不起,我对swift3很新

我做了更改后

let abc = UnsafePointer<UInt32>(array1).withMemoryRebound(to: <#T##T.Type#>,capacity: <#T##Int#>,<#T##body: (UnsafeMutablePointer<T>) throws -> Result##(UnsafeMutablePointer<T>) throws -> Result#>)

但仍然应该对变量有什么价值？对不起,我有搜索但很糟糕,我找不到解决方案

解决方法 你可以试试这个：

let rawPointer = UnsafeRawPointer(array1)let pointer = rawPointer.assumingMemoryBound(to: UInt32.self)let value = pointer.pointee

原始指针是用于访问非类型数据的指针.

assumeMemoryBound(to :)可以从UnsafeRawPointer转换为UnsafePointer< T>.
