小问题:是否可以使用 UIWebViewDelegate 在 UIWebView 中检测 window.open() 还是有其他方法可以达到这?当触发 window.open()-Event 以显示 UIAlertView 时，我需要 url.

Short question: Is it possible to detect window.open() in a UIWebView using the UIWebViewDelegate or is there another way to reach this? I need the the url when a window.open()-Event is fired to show a UIAlertView.

推荐答案

你需要用 JavaScript 覆盖 window.open():

You need to overwrite window.open() using JavaScript:

[webView stringByEvaluatingJavaScriptFromString:@"window.open = function (open) { return function  (url, name, features) { window.location.href = url; return window; }; } (window.open);"];
