SDWebImage 使用 Swift 将图像设置为 CellView 中的 UIButton

SDWebImage Set Image To UIButton in CellView Using Swift

您好,我正在使用 SDWebImage 将图像设置为 xcode 10.2.1 中的按钮。

我正在尝试以下方法

import SDWebImage

cell.bProfileImage.sd_setImage(with:URL(string:
individualChatsListArray[indexPath.row].profile_image), forState:.normal)

但是我收到以下错误

Value of optional type 'UIButton?' must be unwrapped to refer to member
 'sd_setImage' of wrapped base type 'UIButton'

在 nib 文件中,项目按以下链接和声明

@IBOutlet weak var bProfileImage: UIButton!


@IBAction func bProfileImage(_ sender: Any) {

    print("touch kia")

}

我试过了

cell.bProfileImage?.sd_setImage(with:URL(string:
individualChatsListArray[indexPath.row].profile_image), forState:.normal)

但随后出现以下错误

Ambiguous reference to member 'bProfileImage'

如您所见,我是 xcode/swift

的新手

下面没有给出任何错误,但也没有加载图像

cell.bProfileImage.sd_setBackgroundImage(with: URL(string:
individualChatsListArray[indexPath.row].profile_image), for:
UIControl.State.normal) { (image, error, cache, url) in }

以下运行完美。

cell.bProfileImage.sd_setBackgroundImage(with: URL(string:
individualChatsListArray[indexPath.row].profile_image), for:
UIControl.State.normal, placeholderImage: UIImage(named:
"default_profile"), options: SDWebImageOptions(rawValue: 0)) { (image,
error, cache, url) in

}
