如何忽略https认证

使用一个私有API可以忽略证书无效等问题

[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];

注意这是一个私有API，使用这个代码的APP将会被苹果商店拒绝。

另提供2个合法的方式，NSURLConnectionDelegate的

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge

实例代码：

-(BOOL)connection:(NSURLConnection*)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace*)protectionSpace {
  return[protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}

-(void)connection:(NSURLConnection*)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge*)challenge {
  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];
}

如果使用web view来请求网页的话，添加这么一句[NSURLConnection connectionWithRequest:request delegate:self];
