将UIWebView标题发送到UINavigationBar [英] Send UIWebView title to UINavigationBar

问题描述

您好我到处寻找但没有任何帮助，我正在尝试将UIWebView页面标题发送到UINavigationBar。

Hi I have looked everywhere but nothing as help, I am trying to send the UIWebView page Title to UINavigationBar.

如果用户点击，我也会喜欢它一个链接，UINavigationBar显示一个后退按钮，但如果在主页上隐藏后退按钮。

I would also like it if a user clicks on a link the UINavigationBar shows a back button but if on the home page hide the back button.

如果你可以帮助那将是非常好的

If you can help that would be very nice

推荐答案

将标题页检索到UIWebView中，您可以使用它：

to retrieve the title page into an UIWebView you can use it:

myNavigationBar.title = [myWebView stringByEvaluatingJavaScriptFromString:@"document.title"];

如果你想回去，你可以这样做：

If you want to go back you can do that:

if ([myWebView canGoBack]){
    [myWebView goBack];
}

要知道用户是否加载了新页面，您必须设置UIWebViewDelegate。有关详细信息，请参阅 UIWebView类参考和 UIWebViewDelegate Protocol Reference

To know if the user has loaded a new page you must set the UIWebViewDelegate. For more information see the UIWebView Class Reference and the UIWebViewDelegate Protocol Reference
