ios - 在 swift 中使用 `NSDictionary` 时出错

Question

我对 swift 很陌生，我正在尝试在 Collection View 中显示图像集合

我收到此代码错误

let asset: PHAsset = self.photoAsset[indexPath.item] as PHAsset
        PHImageManager.defaultManager().requestImageForAsset(asset, targetSize: PHImageManagerMaximumSize, contentMode: .ScaleAspectFill, options: nil, resultHandler: {
            (result: UIImage!, info: NSDictionary!)in cell.setThumbnailImage(result)

        })

'[NSObject : AnyObject]' 与 'NSDictionary' 不同 是错误，我不知道如何修复它？

帮助说

func requestImageForAsset(_ asset: PHAsset!,
           targetSize targetSize: CGSize,
          contentMode contentMode: PHImageContentMode,
              options options: PHImageRequestOptions!,
        resultHandler resultHandler: ((UIImage!,
            [NSObject : AnyObject]!) -> Void)!) -> PHImageRequestID

你供应

info: NSDictionary!

改变它以便你提供

info: [NSObject : AnyObject]!
