Question

男孩，我是一个菜鸟。无法通过按钮在SWIFT中打开第二个URL。应用程序打开，打开时在WebView中加载URL。现在我想要一个按钮在单击时在WebView中打开另一个URL。（后退按钮，前进按钮并重新加载没有问题）...请帮助，谢谢

导入UIKit

类ViewController：UIViewController {

@IBOutlet var webView: UIWebView!

var URLPath = "http://bandersnatchorlando.com/x19559"

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    loadAddressURL()

}

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


func loadAddressURL(){
    let requestURL = NSURL(string:URLPath)
    let request = NSURLRequest(URL:
    requestURL)
    webView.loadRequest(request)
}

@IBOutlet weak var reLoad: UIButton!
 }

Answer 1

假设你的故事板中已经有了另一个按钮，并且它被链接到@IBAction，然后在动作中：

let url = NSURL(string:"http://myotherurl.com")
let request = NSURLRequest(URL:url)
webView.loadRequest(request)

SWIFT无法使用第二个按钮在UIWebView中打开第二个URL
