iOS HTTPS证书不受信任解决办法

本文主要是介绍iOS HTTPS证书不受信任解决办法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

之前开发App的时候服务端使用的是自签名的证书，导致iOS开发过程中调用HTTPS接口时，证书不被信任

- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler{/*方法一*/if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]){NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];if(completionHandler)completionHandler(NSURLSessionAuthChallengeUseCredential,credential);}/*方法二*/
//    SecTrustRef servertrust = challenge.protectionSpace.serverTrust;
//    SecCertificateRef certi= SecTrustGetCertificateAtIndex(servertrust, 0);
//    NSData *certidata = CFBridgingRelease(CFBridgingRetain(CFBridgingRelease(SecCertificateCopyData(certi))));
//    NSString *path = [[NSBundle mainBundle] pathForResource:@"证书名称" ofType:@"cer"];NSLog(@"证书 ： %@",path);
//    NSData *localCertiData = [NSData dataWithContentsOfFile:path];
//    if ([certidata isEqualToData:localCertiData]) {
//        NSURLCredential *credential = [[NSURLCredential alloc] initWithTrust:servertrust];
//        [challenge.sender useCredential:credential forAuthenticationChallenge:challenge];
//        completionHandler(NSURLSessionAuthChallengeUseCredential, credential);NSLog(@"服务端证书认证通过");
//    }else {
//        completionHandler(NSURLSessionAuthChallengeCancelAuthenticationChallenge, nil);
//        NSLog(@"服务端认证失败");
//    }}

这里有两个方法，第一个是信任所有证书，第二个是把服务端自签名的证书放到本地，类似白名单的样子去加载
