[英]how to do something right after downloading image using SDWebImage?
所以,我想在下載圖像並在 ImageView 中設置后立即向用戶顯示一條消息。 我正在使用 SDWebImage。 怎么做?
這是我當前的代碼
profilePictureImageView.sd_setImage(with: referenceImage, placeholderImage: UIImage(named: ImageName.defaultProfilePicture))
你可以這樣做
profilePictureImageView.sd_setImage(with: referenceImage, placeholderImage: UIImage(named: "cod_logo"), options: [.highPriority]) { (image, error, cashtype, url) in
if image != nil{
// Do something Here after load image
}
print(error) // Your error is here
}
這是pod 'SDWebImage' = '4.0.0'
和 XCode == 11.3.1
self.userAvatar.sd_setImage(with: URL(string: __user_avatar), placeholderImage: UIImage(named: "UserDefalutAvatar"), options: .progressiveDownload, progress: { (receivedSize, expectedSize, targetURL) in
print("The progress value for the downloading is \(receivedSize)")
}) { (downloadedImage, downloadedError, imageCacheType, downloadedURL) in
if let _downloadedError = downloadedError {
print("Download image encountered error. \(_downloadedError.localizedDescription)")
return
}
if let _downloadedImage = downloadedImage {
print("This is downloaded image, you can do it what you want")
}
}
