带有URL内容的字符串？ [英] String With Contents Of URL?

问题描述

因此，在我下载最新更新之前，以下代码对我有用：

So before I downloaded the recent update, the following code worked for me:

var g_home_url = String.stringWithContentsOfURL(NSURL(string: url_string), encoding: NSUTF8StringEncoding, error: nil) // Gives me an error: "String.Type does not have a member names stringWithContentsOfUrl"

我很困惑。在swift中采用以下Objective-c方法的正确方法是什么？

I am confused. What is the proper way to acieve the following objective-c method in swift?

NSString * g_home_url = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:home_url] encoding:NSUTF8StringEncoding error:nil];

推荐答案

使用 -initWithContentsOfURL： encoding：实例方法而不是 + stringWithContentsOfURL：encoding：error： class convenience initializer。

Use the -initWithContentsOfURL:encoding:error: instance method instead of the +stringWithContentsOfURL:encoding:error: class convenience initializer.

var g_home_url = String(contentsOfURL: NSURL(string: url_string)!, encoding: NSUTF8StringEncoding, error: nil)

我不知道Swift现在是否支持类方便初始化器，但是它们才有意义，因为它们只是alloc-init样板的缩写，它没有'存在于Swift中。

I have no idea if class convenience initializers are now unsupported in Swift, but it would make sense as they were just shorthands for the alloc-init boilerplate, which doesn't exist in Swift.
