SDWebImage 找不到 SDImageCacheType

Question

我面临无法使用 SDWebImage 库（用 Objective-C 编写）的完成块的问题。我在几个地方使用了 sd_setImageWithURL，但每次我收到错误 Use of undeclared type 'SDImageCacheType'。该问题出现在 2 台不同的 MacBook 上。我检查了一下，缺少的类型在 SDWebImage.h 文件中声明（附在最后）。我正在使用 CocoaPods。

基本源代码

        imageViewMain.sd_setImageWithURL(NSURL(string: finalURL)) //Works fine

        // Doesn't work.
        let b : SDImageCacheType = SDImageCacheType.None
        let block = {(image: UIImage!, error: NSError!, cacheType: SDImageCacheType.None, imageURL: NSURL!) -> Void in
            println(self)
        }
        imageViewMain.sd_setImageWithURL(NSURL(string: finalURL), completed: block)

好吧，这是一个非常微不足道的问题，我不知道为什么我没有早点弄清楚。我需要做的就是添加一个导入。看起来如果你使用声明的块你需要添加它。

import SDWebImage
