Tag: 不安全指针

Swift 3 UnsafePointer（$ 0）不再在Xcode 8 beta 6中编译

我的代码snipet如下…： let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) { SCNetworkReachabilityCreateWithAddress(nil, UnsafePointer($0)) } …不再编译以下错误，我不明白： "'init' is unavailable: use 'withMemoryRebound(to:capacity:_)' to temporarily view memory as another layout-compatible type." 该怎么做来解决它？

如何在swift中将自我投射到UnsafeMutablePointer <Void>types

在调用下面的代码时，试图快速地将“self”传递给C函数： var callbackStruct : AURenderCallbackStruct = AURenderCallbackStruct.init( inputProc: recordingCallback, inputProcRefCon: UnsafeMutablePointer<Void> ) 在这里将“self”转换为UnsafeMutablePointertypes的理想方式是什么？
