我目前在 Apple Store 上的应用程序具有登录功能。我收到了很多只使用 iPhone 4 的客户的投诉。他们抱怨无法登录自己的帐户。这只发生在 iPhone 4 设备上（也可能是支架设备）。该错误返回一个代码 -1202 (NSURLErrorServerCertificateUntrusted)。我不明白的是它适用于任何较新的设备（iPhone 4S、5、5C 和 5S）。

- (IBAction)didTapButton:(id)sender 
{
   NSURL *url = [NSURL URLWithString:@"MY_LOGIN_URL"];
   NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
   NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
  [connection start];
}

#pragma mark - NSURLConnectionDataDelegate

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
  NSLog(@"Failed");
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSHTTPURLResponse *)response
{
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
  NSLog(@"Succeded");
}

我知道我可以通过植入下面的行来强制应用程序信任服务器，但这不是一个有效的解决方案。

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
  [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
 {
  return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}

如果我添加 didReceiveAuthenticationChallenge 是否足够：

SecTrustRef trustRef = [[challenge protectionSpace] serverTrust];
SecTrustEvaluate(trustRef, NULL);
CFIndex count = SecTrustGetCertificateCount(trustRef);
if(count > 0)
{
  SecCertificateRef certRef = SecTrustGetCertificateAtIndex(trustRef, 0);
  CFStringRef certSummary = SecCertificateCopySubjectSummary(certRef);
  NSString* certSummaryNs = (__bridge NSString*)certSummary;
  if([certSummaryNs isEqualToString:@"MY_API"])
    NSLog(@"Verified");
  else
    NSLog(@"Invalid");
}
else
  NSLog(@"No certificate found");

您是否尝试过需要更改日期和时间的设备设置，并将其自动设置为当前时区。
