ios - 制作从谷歌下载的圆形照片(谷歌地点， swift )

Question

我正在与谷歌地点合作，我有一个带有tableView的VC，我从用户位置下载了附近的地点，并在tableView的每个单元格中添加了该地点的信息及其照片。我创建了一个自定义类来使照片变成圆形

import UIKit

@IBDesignable
class RoundImage: UIImageView {



    @IBInspectable var cornerRadius: CGFloat = 0 {
        didSet {
            self.layer.cornerRadius = cornerRadius
        }
    }
    @IBInspectable var borderWidth: CGFloat = 0 {
        didSet {
            self.layer.borderWidth = borderWidth
        }
    }

    @IBInspectable var borderColor: UIColor = UIColor.clear {
        didSet {
            self.layer.borderColor = borderColor.cgColor
        }
    }

}

但问题是我下载了此类地点的照片

import UIKit

private let widthKey = "width"
private let heightKey = "height"
private let photoReferenceKey = "photo_reference"


class QPhoto: NSObject {


        var width: Int?
        var height: Int?
        var photoRef: String?



        init(photoInfo: [String:Any]) {
            height = photoInfo[heightKey] as? Int
            width = photoInfo[widthKey] as? Int
            photoRef = photoInfo[photoReferenceKey] as? String
        }

        func getPhotoURL(maxWidth:Int) -> URL? {
            if let ref = self.photoRef {
                return NearbyPlaces.googlePhotoURL(photoReference: ref, maxWidth: maxWidth)
            }
            return nil
        }
    }

我想知道如何调整它，因为通过这个类，即使我将 RoundImage 类放在 Storyboard 中的 ImageView 中，我下载的照片始终是方形的

您需要将clipsToBounds设置为true。您可以在设置 cornerRadius 时执行此操作:

@IBInspectable var cornerRadius: CGFloat = 0 {
    didSet {
        self.layer.cornerRadius = cornerRadius
        self.clipsToBounds = true
    }
}
