ios - swift 2.0 UIWebview 只显示白页

Question

我写这段代码:

@IBOutlet weak var webView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    let url = NSURL (string: "http://google.com");
    let requestObj = NSURLRequest(URL: url!);

    webView.loadRequest(requestObj);
    self.view.addSubview(webView)
}

运行代码，iPhone模拟器只显示白页，没有警告错误

然后我将代码更改为:

let url = NSURL (string: "http://apple.com");

把google换成apple就可以了-模拟器显示apple网站

所以我把另一个网站 url 但它和第一个一样，只是它显示 apple.com

我不知道这段代码有什么问题请帮助我!谢谢:)

Answer 1

你应该得到错误:

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app's Info.plist file.

如下图所示查找信息并执行以下步骤:

1.On the last line add the +
2.Enter the name of the group: App Transport Security
3.Right click on the group and select Add Row
4.Enter Allow Arbitrary Loads
5.Set the value on the right to YES

如果你已经从 storyboard 连接它就不需要这行

self.view.addSubview(webView)
