WKwebview内容涵盖了顶级状态栏

标签: ios swift wkwebview

我按照this教程创建了一个WKwebview,但有一个问题。顶部状态栏由webView的内容覆盖。

由于webView是containerView,因此webView如何进入代码中的状态栏。感谢

import UIKit
import WebKit

class ViewController: UIViewController {
@IBOutlet var mainView : UIView?
var webView: WKWebView?

override func loadView() {
    super.loadView() // call parent loadView
    self.webView = WKWebView() // instantiate WKWebView
    self.view = self.webView! // make it the main view
}

override func viewDidLoad() {
    super.viewDidLoad() // run base class viewDidLoad
    let url = NSURL(string:"https://www.google.com") // make a URL
    let req = NSURLRequest(URL:url!) // make a request w/ that URL
    self.webView!.loadRequest(req) // unwrap the webView and load the request.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

这是最终为我工作的东西(非常类似于Herbert Bay的回答)。

<强>夫特:

class ViewController: UIViewController, WKNavigationDelegate {

    let webView = WKWebView()

    override func viewDidLoad() {
        // Get height of status bar (iPhone X introduced a new status bar)
        let statusBarHeight = UIApplication.shared.statusBarFrame.height
        // Initialize the frame
        webView.frame = CGRect.init(x: 0, y: statusBarHeight, width: view.bounds.maxX, height: view.bounds.maxY)
        // Set background color of status bar (optional)
        self.view.backgroundColor = UIColor(red: 248/255.0, green: 248/255.0, blue: 248/255.0, alpha: 1.0)
    }
}

CGRect.init()中的 y 设置为状态栏的高度,可以消除Web视图和状态栏的任何重叠。

我会将WKWebView添加为容器视图的子视图,并使用状态栏的大小来初始化WKWebView initWithFrame。很高兴知道是否有更好的方法。

WKWebViewConfiguration *webViewConfiguration = [[WKWebViewConfiguration alloc] init];
CGFloat heightStatusBar = [UIApplication sharedApplication].statusBarFrame.size.height;
self.webView = [[WKWebView alloc] initWithFrame:CGRectMake(0.0, heightStatusBar,
                                                           self.view.frame.size.width,
                                                           self.view.frame.size.height-heightStatusBar)
                                  configuration:webViewConfiguration];
[self.view addSubview:_webView];

webView.translatesAutoresizingMaskIntoConstraints = false
    if #available(iOS 11.0, *) {
        webView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor).isActive = true
    } else {
        // Fallback on earlier versions
        webView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
    }
    webView.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true
    webView.rightAnchor.constraint(equalTo: view.rightAnchor).isActive = true
    if #available(iOS 11.0, *) {
        webView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor).isActive = true
    } else {
        webView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
    }

我通过在主“根”视图中嵌入容器视图解决了这个问题,然后在容器内放置了一个webView,从而能够通过设置约束来控制容器显示在状态栏下

  

Container View.top =顶部布局Guide.bottom

我必须说我很惊讶于这么多在线教程可以从一些抛光/升级中受益,“读者要小心”,这在你学习时很难叹息。
