SDWebImage使用Swift將圖像設置為CellView中的UIButton

Question

嗨我正在使用SDWebImage將圖像設置為xcode 10.2.1中的按鈕。

我正在嘗試以下方面

import SDWebImage

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

但是我收到以下錯誤

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

在nib文件中，項目鏈接並按以下方式聲明

@IBOutlet weak var bProfileImage: UIButton!


@IBAction func bProfileImage(_ sender: Any) {

    print("touch kia")

}

我努力了

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

但后來得到以下錯誤

Ambiguous reference to member 'bProfileImage'

如你所見，我是xcode / swift的新手

以下內容未給出任何錯誤，但也未加載圖像

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

Answer 1

以下是完美的工作。

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

}
