我想改变图像的色调但无法改变,它总是返回白色。我已经尝试过原始图像和模板图像的渲染图像,但仍然不起作用。
我在下面添加了屏幕截图:
请任何人都可以帮助我
public func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
guard let cell = tableView.cellForRow(at: indexPath) as? DocumentListCell else {return UISwipeActionsConfiguration()}
let likeAction = UIContextualAction(style: .normal, title: "", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("likeAction ...")
success(true)
})
likeAction.image = #imageLiteral(resourceName: "Favourite_Selected")
likeAction.backgroundColor = UIColor.init(red: 239/255, green: 239/255, blue: 239/255, alpha: 1)
let downloadAction = UIContextualAction(style: .normal, title: "", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("Trash action ...")
})
downloadAction.backgroundColor = UIColor.red//UIColor.init(red: 239/255, green: 239/255, blue: 239/255, alpha: 1)
downloadAction.image = #imageLiteral(resourceName: "Doc_Download_Big")
return UISwipeActionsConfiguration(actions: [likeAction,downloadAction])
}
最佳答案
- 只需前往
Assets.xcassets
,选择所需的图像。
<小时/>Replace
Render As
with the one you need:
添加
您还可以尝试一些方法:
- Change the settings of the
UIImageView
itself inside yourtableView
:
UIImageView.appearance(whenContainedInInstancesOf: [UITableView.self]).tintColor = UIColor.init(red: 239/255, green: 239/255, blue: 239/255, alpha: 1)
- Try to use extension on
UIImage
:
extension UIImage {
func paintOver(with color: UIColor) -> UIImage {
let renderer = UIGraphicsImageRenderer(size: size)
let renderedImage = renderer.image { _ in
color.set()
self.withRenderingMode(.alwaysTemplate).draw(in: CGRect(origin: .zero, size: size))
}
return renderedImage
}
}
使用方法:
likeAction.image = UIImage(named: "Favourite_Selected")?.colored(in: .red)
