iphone - 为什么某些 Https url 没有加载到 WebView 中？

Question

为什么有些 https 链接没有加载 WebView。我可以看到一些 https url 在 safari 浏览器中完美加载，但是当我尝试在 webview 中加载相同的 url 时，它没有加载。可能是因为https有自签名证书？？我们不能在具有自签名证书的 WebView 中加载 url 吗？

编辑：现在我可以打电话了

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace 
{
    return YES;
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge 
{
    [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}

我的 https url 仍然没有加载到 WebView 中。

Answer 1

试试这个 ：

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace 
{
  return YES;
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
NSArray *trustedHosts = [NSArray arrayWithObjects:@"mytrustedhost",nil];

if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]){
    if ([trustedHosts containsObject:challenge.protectionSpace.host]) {
    [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
    }
}
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
