我有这个功能从资产中获取图像:

func fetchImage(asset: PhotoAsset, size: CGSize, resizeMode: ResizeMode = .Exact, completion: (result: UIImage?) -> Void) {
        let photoAsset = asset as! PHAsset
        var options: PHImageRequestOptions?
        switch resizeMode {
            case .Exact:
                options = PHImageRequestOptions()
                options?.resizeMode = .Exact
            case .Default:
                options = nil
        }
        manager.requestImageForAsset(
            photoAsset,
            targetSize: size,
            contentMode: .AspectFill,
            options: options
        ) { [weak self] result, _ in
            completion(result: result)
        }
    }

但我如何定义以获取原始大小的图像？

谢谢!

如何检查UIImage是否为风景图像(在Swift中)？

我试过这段代码:

if self.imageView.image?.imageOrientation == .Left || self.imageView.image?.imageOrientation == .Right {
            self.isLandscape=true
        }

但它不起作用.

谢谢
