以下代码给出了编译器错误“使用未声明的类型AutoreleasingUnsafePointer”

var myString: AutoreleasingUnsafePointer<NSString?>

我错过了编译器设置步骤吗？

谢谢

解决方法

如 documentation revision history所述

Updated the Pointers section to reflect that UnsafePointer has been replaced with UnsafeMutablePointer,ConstUnsafePointer has been replaced with UnsafePointer,and AutoreleasingUnsafePointer has been replaced with AutoreleasingUnsafeMutablePointer.

所以你必须使用AutoreleasingUnsafeMutablePointer
