UIWebView，goBack访问后退列表？ [英] UIWebView, goBack accessing back-forward list?

问题描述

我只是快速浏览UIWebView，并编写了一个带有后退按钮，UITextField和前进按钮的小型浏览器。会发生以下情况：

I am just having a quick look at UIWebView and have written a small browser with a back button, a UITextField and a forward button. Here is what happens:

1. 我在文本字段中输入 www.google.com，然后转到页面。


2. 文本字段显示 www.google.com


3. 我输入 www.apple.com，然后转到页面。


4. 文本字段显示 www.apple.com


5. 我点击后退按钮并返回 www.google.com


6. textField仍然显示 www.apple.com

1. I enter "www.google.com" into the textField and it goes to the page.
2. The textField says "www.google.com"
3. I enter "www.apple.com" and it goes to the page.
4. The textField says "www.apple.com"
5. I tap the back button and return to "www.google.com"
6. The textField still says "www.apple.com"

我添加了：

-(IBAction)myGoBack {
    NSLog(@"myGoBack ...");
    [webView goBack];
}

我的问题是，当我打电话给goBack时，有没有办法是从后退列表中加载的，以便我可以更新UITextFiled？

My question is, is there a way when I call goBack to access the location that is loaded from the back-forward list so that I can update my UITextFiled?

推荐答案

您可以从UIWebView的request属性中获取当前URL并设置地址栏文本，例如

You can get the current URL from the UIWebView's request property and set the address bar text like this

- (void) webViewDidFinishLoad:(UIWebView *) webView {
    [addressBar setText:self.webView.request.URL.absoluteString];

}
