在Swift 5.1中,你可以通过以下步骤来添加图片、文本和UISwitch到UIAlertAction中:
let action = UIAlertAction(title: "Action Title", style: .default, handler: nil)
let stackView = UIStackView()
stackView.axis = .horizontal
stackView.alignment = .center
stackView.spacing = 10
let imageView = UIImageView(image: UIImage(named: "imageName"))
imageView.widthAnchor.constraint(equalToConstant: 30).isActive = true
imageView.heightAnchor.constraint(equalToConstant: 30).isActive = true
let label = UILabel()
label.text = "Action Description"
let switchControl = UISwitch()
switchControl.isOn = true
switchControl.addTarget(self, action: #selector(switchValueChanged(_:)), for: .valueChanged)
stackView.addArrangedSubview(imageView)
stackView.addArrangedSubview(label)
stackView.addArrangedSubview(switchControl)
action.accessoryView = stackView
完整的代码示例如下:
let action = UIAlertAction(title: "Action Title", style: .default, handler: nil)
let stackView = UIStackView()
stackView.axis = .horizontal
stackView.alignment = .center
stackView.spacing = 10
let imageView = UIImageView(image: UIImage(named: "imageName"))
imageView.widthAnchor.constraint(equalToConstant: 30).isActive = true
imageView.heightAnchor.constraint(equalToConstant: 30).isActive = true
let label = UILabel()
label.text = "Action Description"
let switchControl = UISwitch()
switchControl.isOn = true
switchControl.addTarget(self, action: #selector(switchValueChanged(_:)), for: .valueChanged)
stackView.addArrangedSubview(imageView)
stackView.addArrangedSubview(label)
stackView.addArrangedSubview(switchControl)
action.accessoryView = stackView
这样,你就成功地在UIAlertAction中添加了图片、文本和UISwitch。
