步骤如下：
一、新建一个NSURLRequest的类别
二、在这个类别中新增两个类方法，如下：
+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host {
return YES;
}
+ (void)setAllowsAnyHTTPSCertificate:(BOOL)allow forHost:(NSString *)host {
}
注：这两个方法是系统的私有方法。
三、实现WKWebView的代理方法(- (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler)，实现代码如下：
#pragma mark - wkwebview信任https接口
- (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential * _Nullable credential))completionHandler {
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
NSURLCredential *card = [[NSURLCredential alloc]initWithTrust:challenge.protectionSpace.serverTrust];
completionHandler(NSURLSessionAuthChallengeUseCredential, card);
}
}
四、在加载webView的URL之前调用
[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:@"https"];
这行代码即可。
