ios UIWebView加载https出现 load page error:Error Domain=NSURLErrorDomain Code=-1202 "此服务器的证书无效
出现此类问题，先将plist文件中 allow Arbitrary Loads 设置为true。
以下解决办法
1.在webview的vc中 声明NSURLConnection *_urlConnection;
NSURLRequest *_request;
BOOL _authenticated;
2.在webview的vc中加入以下方法
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;
{
if (!_authenticated) {
_authenticated =NO;
_urlConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
_request = request;
[_urlConnection start];
return NO;
}
return YES;
}
#pragma mark - NURLConnection delegate
- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
if ([challenge previousFailureCount] == 0)
{
_authenticated = YES;
NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
[challenge.sender useCredential:credential forAuthenticationChallenge:challenge];
} else
{
[[challenge sender] cancelAuthenticationChallenge:challenge];
}
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
// remake a webview call now that authentication has passed ok.
_authenticated = YES;
[self.webView loadRequest:_request]; // self.webView替换成自己的webview
// Cancel the URL connection otherwise we double up (webview + url connection, same url = no good!)
[_urlConnection cancel];
}
// We use this method is to accept an untrusted site which unfortunately we need to do, as our PVM servers are self signed.
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}
这样就可以正常加载webView了
