iOS HTTPS证书不受信任解决办法

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，*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
