弃用具有多个参数的重命名方法 [英] Deprecating renamed method with multiple arguments

问题描述

我想为Swift 3更新以下方法的命名方式:

I wanted to update the naming of the following method for Swift 3:

public func imageWithUrl(url: String, placeholderNamed: String) {
    if let image = UIImage(named: placeholderNamed) {
        imageWithUrl(url: url, placeholder: image)
    } else {
        imageWithUrl(url: url)
    }
}

到

public func image(url: String, placeholderNamed: String) {

因此，我弃用了旧方法:

So I deprecated the old method with this:

@available(*, deprecated: 1.8, renamed: "image(url:, placeholder:")

问题是我遇到以下错误:

The problem is that I'm getting the following error:

"available"属性的"renamed"参数必须是运算符，标识符或完整的函数名，可以选择以类型名作为前缀

'renamed' argument of 'available' attribute must be an operator, identifier, or full function name, optionally prexied by a type name

推荐答案

我在renamed:部分遇到了问题.为了解决这个问题，只需将其更改为

I was having a problem with the renamed: part. In order to fix that, just change it to

@available(*, deprecated: 1.8, renamed: "image(url:placeholder:)")
