stringByAppendingPathComponent不可用 [英] stringByAppendingPathComponent is unavailable

问题描述

我的应用在Instagram上分享照片，为此，首先将其保存在临时目录中：

My app shares photo on Instagram, to do this it first saves it on a temporary directory:

let writePath = NSTemporaryDirectory().stringByAppendingPathComponent("instagram.igo")

它正在使用 Swift 1.2 ，但不适用于 Swift 2.0 。

It was working on Swift 1.2, but does not work on Swift 2.0.

给出错误消息是：

stringByAppendingPathComponent不可用：改为使用NSURL上的URLByAppendingPathComponent。

stringByAppendingPathComponent is unavailable: use URLByAppendingPathComponent on NSURL instead.

推荐答案

看起来在Swift 2.0中删除了 stringByAppendingPathComponent 方法，所以错误信息建议使用：

It looks like the method stringByAppendingPathComponent is removed in Swift 2.0, so what the error message suggests is to use:

let writePath = NSURL(fileURLWithPath: NSTemporaryDirectory()).URLByAppendingPathComponent("instagram.igo")

更新：

URLByAppendingPathComponent（）已替换为 ap pendingPathComponent（）所以改为：

let writePath = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent("instagram.igo")
