SDWebImage找不到SDImageCacheType

Question

我面临的问题是我不能使用SDWebImage库的完成块(用Objective编写)。我在几个地方使用sd_setImageWithURL，但是每次我收到错误使用未声明类型'SDImageCacheType‘时。这一问题发生在两个不同的MacBooks上。我检查并在SDWebImage.h文件中声明了缺失的类型(附在末尾)。我在用CocoaPods。

子网源代码

        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，那是个很小的问题，我不知道为什么我不早点解决。我所需要做的就是添加一个导入。看起来，如果使用声明的块，则需要添加它。

import SDWebImage
