内部名称swift 2.0+？(Internal name swift 2.0+? [duplicate])

内部名称swift 2.0+？(Internal name swift 2.0+? [duplicate])

这个问题在这里已有答案：

快速语言 5答案中 '＃'标记的含义是什么？

在更新到swift 2.0+之前，它有效。 现在没有内部参数？

我该如何更改然后让它正常工作？

我发现我需要删除“func”和“＃”但它没有帮助D：

func previewFile(#path: NSIndexPath) { UIApplication.sharedApplication().networkActivityIndicatorVisible = false self.fileIsLoading = false let previewQL = QLReaderViewController() previewQL.dataSource = self previewQL.delegate = self previewQL.hidesBottomBarWhenPushed = true self.filepath = path self.navigationController?.pushViewController(previewQL, animated: true) }

所以我这样做了...... 在这里输入图像描述

但如果我删除这个“路径”它会正常工作吗？ 为什么声明参数被改变了？ 我的意思是 - 它有效。 但为什么

previewFile(indexPath!)

代替

previewFile(path: indexPath!)

This question already has an answer here:

What is the meaning of the '#' mark in swift language 5 answers

Before update to swift 2.0+ it worked. Now there is no internal parameters?

How should I change it then to let it work correctly?

I found out that I need to delete "func" and "#" but it didn't help D:

func previewFile(#path: NSIndexPath) { UIApplication.sharedApplication().networkActivityIndicatorVisible = false self.fileIsLoading = false let previewQL = QLReaderViewController() previewQL.dataSource = self previewQL.delegate = self previewQL.hidesBottomBarWhenPushed = true self.filepath = path self.navigationController?.pushViewController(previewQL, animated: true) }

So i did so ... enter image description here

But if i delete this "path" would it work correctly? Why declaration of a parameter was changed so? I mean - it works. But why

previewFile(indexPath!)

instead of

previewFile(path: indexPath!)

最满意答案

您不能再使用＃作为内部参数命名。 您应该编写如下函数：

func previewFile(path path: NSIndexPath) { // Your code }

You can't use # for internal argument naming anymore. You should write the function like:

func previewFile(path path: NSIndexPath) { // Your code }
