addSubview SwiftUI View to UIKit UIView in Swift
addSubview SwiftUI View to UIKit UIView in Swift
我已经尝试 addSubview
SwiftUI View 到 UIView。 self.view.addSubview(contentView)
Error: Cannot convert value of type 'ContentView' to expected argument type
'UIView'
请帮助我实现这个 UI。
import UIKit
import SwiftUI
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
view.backgroundColor = UIColor.lightGray
let contentView = ContentView()
view.addSubview(contentView) // Error: Cannot convert value of type 'ContentView' to expected argument type 'UIView'
}
}
struct ContentView: View {
var body: some View {
Text("Hello world")
}
}
第 1 步:
使用 SwiftUI View
创建 UIHostingController 实例
struct ContentView : View {
var body: some View {
VStack {
Text("Test")
Text("Test2")
}
}
}
var child = UIHostingController(rootView: ContentView())
第 2 步:
将 UIHostingController 的实例作为子视图控制器添加到 Any UIKit ViewController
var parent = UIViewController()
child.view.translatesAutoresizingMaskIntoConstraints = false
child.view.frame = parent.view.bounds
// First, add the view of the child to the view of the parent
parent.view.addSubview(child.view)
// Then, add the child to the parent
parent.addChild(child)
您可以使用以下代码删除子控制器
从视图控制器中移除
// Then, remove the child from its parent
child.removeFromParent()
// Finally, remove the child’s view from the parent’s
child.view.removeFromSuperview()
