私はこれを行う方法を見つけました:
1) ページが読み込まれると失敗するため、次のような内容を didFailLoadWithError に追加します。
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
if ([error.domain isEqualToString: NSURLErrorDomain])
{
if (error.code == kCFURLErrorServerCertificateHasBadDate ||
error.code == kCFURLErrorServerCertificateUntrusted ||
error.code == kCFURLErrorServerCertificateHasUnknownRoot ||
error.code == kCFURLErrorServerCertificateNotYetValid)
{
display dialog to user telling them what happened and if they want to proceed
2) ユーザーがページをロードしたい場合は、NSURLConnection を使用して接続する必要があります。
NSURLRequest *requestObj = [NSURLRequest requestWithURL:self.currentURL cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:10.0];
self.loadingUnvalidatedHTTPSPage = YES;
[self.webView loadRequest:requestObj];
3) 次に、この変更を shouldStartLoadWithRequest に加えます。
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
if (self.loadingUnvalidatedHTTPSPage)
{
self.connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[self.connection start];
return NO;
}
4) NSURLConnectionDelegate を次のように実装します。
- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
SecTrustRef trust = challenge.protectionSpace.serverTrust;
NSURLCredential *cred;
cred = [NSURLCredential credentialForTrust:trust];
[challenge.sender useCredential:cred forAuthenticationChallenge:challenge];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;
{
NSURLRequest *requestObj = [NSURLRequest requestWithURL:self.currentURL cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:10.0];
self.loadingUnvalidatedHTTPSPage = NO;
[self.webView loadRequest: requestObj];
[self.connection cancel];
}
それはすべてうまくいくようです。
