cocoa-touch – 在iOS应用中显示不受信任的证书信息

Q2：这是您的决定 – 如果您的服务器运行自己的证书并且您希望以这种方式保留(如企业应用程序那样),只需验证证书SHA1或MD5是您期望的(这就是我们在应用).

这意味着你需要一个实现NSURLConnectionDelegate或NSURLConnectionDataDelegate的类(如果你想要数据的处理程序)

然后实现这个方法：

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
    NSLOG(@"connection canAuthaenticateAgainstProtectionSpace");
    if (![Certificates verifyProtectionSpace:protectionSpace]) { //this to verify your own certificate which is self signed.
        NSLOG(@"Bad Certificate,canceling request");
        [connection cancel];
        self.ended = true;
        return false;
    }
    return true;
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChALLENge:(NSURLAuthenticationChALLENge *)chALLENge
{
    NSLOG(@"connection didReceiveAuthenticationChALLENge");
    if ([Certificates verifyProtectionSpace:chALLENge.protectionSpace]) { //this is where you verify the certificates again - for non self-signed ones usually.
        [chALLENge.sender useCredential:[NSURLCredential credentialForTrust:chALLENge.protectionSpace.serverTrust] forAuthenticationChALLENge:chALLENge];
    } else {
        [chALLENge.sender performDefaultHandlingForAuthenticationChALLENge:chALLENge];
    }
}
