stringByExpandingTildeinPath不可用

Question

转换项目后，我在Swift 2中收到以下错误：

stringByExpandingTildeinPath is unavailable: use stringByExpandingTildeinPath on NSString instead

这是我用来与Swift 1.2中的whatsapp共享的代码，第3行的错误：

                let filename = "myimage.wai"
                let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, false)[0] as NSString
                let destinationPath = documentsPath.stringByAppendingString("/" + filename).stringByExpandingTildeInPath

Answer 1

你为什么要求它不扩展addr然后自己花费？更简单的让API自己处理它：

addr
