stringByAppendingPathComponent 不可用 [英] stringByAppendingPathComponent is unavailable

问题描述

我的应用在 Instagram 上分享照片，为此它首先将它保存在一个临时目录中:

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

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

它适用于 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.

给定的错误信息是:

stringByAppendingPathComponent 不可用:在 NSURL 上使用 URLByAppendingPathComponent 代替.

stringByAppendingPathComponent is unavailable: use URLByAppendingPathComponent on NSURL instead.

推荐答案

看起来方法 stringByAppendingPathComponent 在 Swift 2.0 中被删除了，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() 已被 appendingPathComponent() 取代，所以改为:

URLByAppendingPathComponent() has been replaced by appendingPathComponent() so instead do:

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