如何从 UIWebView ios 中显示的 pdf 加载 Safari 中的链接

Question

I am using the Page View Application to show a series of PDF's. The UIWebView is displaying the PDF's fine, however whenever there is a link that is embedded into the PDF and the user clicks it, it opens the link inside of the UIWebView. I want it to open said link in safari.

NSString *path = [[NSBundle mainBundle] pathForResource:page ofType:@"pdf"];
NSURL *targetURL = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];


[self.webView loadRequest:request];

-(BOOL) webView:(UIWebView *)inWeb shouldStartLoadWithRequest:(NSURLRequest *)inRequest navigationType:(UIWebViewNavigationType)inType {
    if ( inType == UIWebViewNavigationTypeLinkClicked ) {
        [[UIApplication sharedApplication] openURL:[inRequest URL]];
        return NO;
    }

    return YES;
}

如您所见，我尝试插入代码来启动它，但单步执行时 BOOL 永远不会运行。

使用这个：-

-(BOOL) webView:(UIWebView *)inWeb shouldStartLoadWithRequest:(NSURLRequest *)inRequest navigationType:(UIWebViewNavigationType)inType {
if ( inType == UIWebViewNavigationTypeLinkClicked || inType ==UIWebViewNavigationTypeOther) {
    [[UIApplication sharedApplication] openURL:[inRequest URL]];
    return NO;
}

return YES;
}

UIWebViewNavigationTypeLinkClicked 在用户点击样式链接时发生，如果更改是从 Javascript 中完成的（例如 onclick 事件），则使用 UIWebViewNavigationTypeOther。

此外，如果您首先加载页面，则使用 UIWebViewNavigationTypeOther，否则您将被元刷新或其他东西重定向
