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
}
