在IOS中，使用自签名证书或者没有达到苹果要求的证书时，需要在INFO.LIST中加入字段
在XCODE中使用sorce code的方式直接编辑加入如下内容

    <key>NSAppTransportSecurity</key>    <dict>        <key>NSAllowsArbitraryLoads</key>        <true/>    </dict>

加了以上内容后，如果使用自签名的证书，会提示如下内容
The certificate for this server is invalid. You might be connecting to a server that is pretending to be “xxxxx.com.cn” which could put your confidential information at risk.
NSURLSession需要设置代理NSURLSessionDelegate
控制器要实现如下方法

@interface ViewController ()<NSURLSessionDelegate>@end@implementation ViewController- (void)URLSession:(NSURLSession *)session didReceiveChallenge:(nonnull NSURLAuthenticationChallenge *)challenge completionHandler:(nonnull void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential * _Nullable))completionHandler{    NSLog(@"%@",challenge.protectionSpace.host);    NSURLCredential *urlCre = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];    completionHandler(NSURLSessionAuthChallengeUseCredential,urlCre);}- (void)viewDidLoad {    [super viewDidLoad];    NSURLSession *ses = [NSURLSession sessionWithConfiguration:nil delegate:self delegateQueue:[NSOperationQueue currentQueue]] ;}

最后就可以正常访问HTTPS网址了。
