这是我曾经遭遇过的最不幸的事情。我有一个UIWebView。它转到http://m.youtube.com。我希望我按下的任何后续链接然后发送到Safari，而不是UIWebView。简单吧？这是你一遍又一遍找到的代码：
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
}
return YES;
}
但这不起作用。所以我将UIWebViewNavigationTypeLinkClicked更改为UIWebViewNavigationTypeOther。当视图加载时，这会在Safari中立即打开。再也不是我想要的。所以我这样做了：
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
if (navigationType == UIWebViewNavigationTypeOther) {
NSLog(@"It works!");
// [[UIApplication sharedApplication] openURL:[NSURL URLWithString:[urlArr objectAtIndex:indexPath.row]]];
return YES;
}
return NO;
}
检查后续点击是否经过这里，但他们没有。日志只显示“它有效！”当视图最初加载时。任何后续点击都不会显示任何内容。
所以我一直在寻找一个URL更改和Javascript更改，但仍然没有。还有什么我可以做的吗？
（顺便提一下，我应该提一下，这个代码可以在任何其他网站上运行，比如stackoverflow.com - 任何后续链接点击，我都会被带到Safari。它只适用于YouTube）< /强>
当我按下youtube上的链接时，这是我从日志中获得的信息：
