翠鸟：'setBackgroundImage(with:for:placeholder:options:progressBlock:completionHandler:)' 的使用不明确

Question

我一直在尝试使用 Kingfisher 设置按钮的背景图像，但我遇到了 swift 编译器错误：

Ambiguous use of 'setBackgroundImage(with:for:placeholder:options:progressBlock:completionHandler:)'

这个表达有歧义怎么办？我查看了 KF 文档，我认为这就是您的称呼。

var options: KingfisherOptionsInfo = []
options.append(.forceRefresh)
button.kf.setBackgroundImage(with: URL(string: picture), for: .normal, placeholder: nil, options: options, progressBlock: nil, completionHandler: nil)

Answer 1

该错误是因为您需要处理 completionHandler 而不是传递 nil。试试下面的代码：

button.kf.setBackgroundImage(with: URL(string: picture), for: .normal, placeholder: nil, options: options, progressBlock: nil) { result in
    // result is either a .success(RetrieveImageResult) or a .failure(KingfisherError)
    switch result {
    case .success(let value):
        // The image was set to image view:
        print(value.image)

        // From where the image was retrieved:
        // - .none - Just downloaded.
        // - .memory - Got from memory cache.
        // - .disk - Got from disk cache.
        print(value.cacheType)

        // The source object which contains information like `url`.
        print(value.source)

    case .failure(let error):
        print(error) // The error happens
    }
}

Answer 2

我有同样的问题，我通过删除函数调用中的 nil 参数解决了这个问题。

imgBanner.kf.setImage(with: url , placeholder:#imageLiteral(resourceName: "landscape.png"), options: nil, progressBlock: nil, completionHandler: nil)

和

 imgBanner.kf.setImage(with: url , placeholder:#imageLiteral(resourceName: "landscape.png"))

Answer 3

为swift5

用这个替换你的行。

videoImageView.kf.setImage(with: resource, placeholder: nil, options: [.transition(.fade(0)), .processor(p)], progressBlock: nil) { (result) in
                
}

Answer 4

我通过剥离未使用参数的函数调用（我们传递 nil 的地方）并导入 Kingfisher 来解决它。

步骤 1。 import Kingfisher

步骤 2。 button.kf.setBackgroundImage(with: URL(string: urlString), for: .normal, options: options)

Answer 5

这对我来说非常基本的修复，使用 URL(string: url) 而不仅仅是字符串 url Xcode 需要特定类型

cell.imgView.kf.setImage(
            with: URL(string: url),
            placeholder: UIImage(named: "dummyaadhar"),
            options: [
                .processor(processor),
                .scaleFactor(UIScreen.main.scale),
                .transition(.fade(1)),
                .cacheOriginalImage
            ])
