ios - 尝试使用 UIWebView 加载 10 个网页后应用程序崩溃

Question

我正在制作一个可以点餐的应用程序。我到达了 paypal 上 UIWebView 页面的结账位置。问题是他们一次加载 9 或 10 个不同的网页。我想知道它们是否是一种使其仅在需要时加载的方法。

import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var webView: UIWebView!
    @IBOutlet weak var webView1: UIWebView!
    @IBOutlet weak var webView2: UIWebView!
    @IBOutlet weak var webView3: UIWebView!
    @IBOutlet weak var webView4: UIWebView!
    @IBOutlet weak var webView5: UIWebView!
    @IBOutlet weak var webView6: UIWebView!
    @IBOutlet weak var webView7: UIWebView!
    @IBOutlet weak var webView8: UIWebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        let url = NSURL(string: "https://mms-lunch-order.000webhostapp.com/12count/pay.html")
        let request = NSURLRequest(URL: url!)
        webView.loadRequest(request)

        let url1 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/spicychicken6th/pay2.html")
        let request1 = NSURLRequest(URL: url1!)
        webView1.loadRequest(request1)

        let url2 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/chickensandwhich6th/pay3.html")
        let request2 = NSURLRequest(URL: url2!)
        webView2.loadRequest(request2)

        let url3 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/12count7/pay4.html")
        let request3 = NSURLRequest(URL: url3!)
        webView3.loadRequest(request3)

        let url4 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/spicychicken7/pay9.html")
        let request4 = NSURLRequest(URL: url4!)
        webView4.loadRequest(request4)

        let url5 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/chickensandwhich7/pay7.html")
        let request5 = NSURLRequest(URL: url5!)
        webView5.loadRequest(request5)

        let url6 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/12count8/pay5.html")
        let request6 = NSURLRequest(URL: url6!)
        webView6.loadRequest(request6)

        let url7 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/spicychicken8/pay10.html")
        let request7 = NSURLRequest(URL: url7!)
        webView7.loadRequest(request7)

        let url8 = NSURL(string: "https://mms-lunch-order.000webhostapp.com/chickensandwhich8/pay8.html")
        let request8 = NSURLRequest(URL: url8!)
        webView8.loadRequest(request8)
    }

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

这是评论，因为我没有足够的声誉。

我认为可能是@IBOutlet没有正确连接，请您检查一下
