不推荐使用NSString stringWithContentsOfURL。我该怎么办？ [英] NSString stringWithContentsOfURL is deprecated. What should I do?

问题描述

我编写了一些使用 stringWithContentsOfURL 的代码，但事实证明它已被弃用。你能帮我换一下吗？这是我的代码：

I've written some code that uses stringWithContentsOfURL, but it turns out that it is now deprecated. Can you help me replace it? Here's my code:

NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString]];
NSArray *listItems = [locationString componentsSeparatedByString:@","];

此外，有人可以提供一些示例代码来说明它的工作原理吗？原始代码的编码是什么（在上面的2行中）？

Additionally, can someone have some sample code to show how it works? What encoding was the original code done in (in my 2 lines above)?

我想保持兼容性，那么我应该为编码选择什么？错误意味着什么以及它用于什么？

I want to maintain compatibility so what should I choose for the encoding? What does error mean and what is it used for?

推荐答案

使用 stringWithContentsOfURL：encoding：error：

编辑：这是使用上述方法的代码：

Here's your code using the above method:

NSError *error = nil;
NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSUTF8StringEncoding error:&error];
NSArray *listItems = [locationString componentsSeparatedByString:@","];

您可以相应地更改 NSUTF8StringEncoding 以获取任何数据你正在进口。

You can change NSUTF8StringEncoding accordingly for whatever data you're importing.
