我是Swift 3.0的新手,我需要一些帮助...
我正在尝试创建一个应该显示网站的框架。该网站不应该填写整个视图,而只是填充框架。每次我启动应用程序时,网站都会填满整个屏幕,而不仅仅是框架...... :(
这是我的代码:
import UIKit
import WebKit
class ViewController: UIViewController, WKUIDelegate {
@IBOutlet weak var webView: WKWebView!
override func loadView() {
let webConfiguration = WKWebViewConfiguration()
webView = WKWebView(frame: .zero, configuration: webConfiguration)
webView.uiDelegate = self
view = webView
}
override func viewDidLoad() {
super.viewDidLoad()
let myURL = URL(string: "https://www.google.com/")
let myRequest = URLRequest(url: myURL!)
webView.load(myRequest)
}
}
我想要的是什么:

答案 0 :(得分:3)
使用相等的填充为webview添加约束(锚点)。
尝试使用故事板布局:
从您的文件中删除loadView()
代码:
或者以编程方式尝试:
import UIKit
import WebKit
class WebKitController: UIViewController {
@IBOutlet weak var webView: WKWebView!
override func viewDidLoad() {
super.viewDidLoad()
let myURL = URL(string: "https://www.google.com/")
let myRequest = URLRequest(url: myURL!)
setupWKWebViewConstraints()
webView.load(myRequest)
}
// add constraints to your web view
func setupWKWebViewConstraints() {
let paddingConstant:CGFloat = 30.0
webView.translatesAutoresizingMaskIntoConstraints = false
webView.topAnchor.constraint(equalTo: self.view.topAnchor, constant: paddingConstant).isActive = true
webView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor, constant: -paddingConstant).isActive = true
webView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor, constant: paddingConstant).isActive = true
webView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor, constant: -paddingConstant).isActive = true
}
}
