https请求处理方式（信任一切证书）
ios https请求处理方式1：信任一切证书
处理方法
1：使用异步请求方式
2：证书信任的委托这样处理
-(BOOL)connectionShouldUseCredentialStorage:(NSURLConnection *)connection{
return true;
}
- (void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{
NSLog(@"didReceiveAuthenticationChallenge %@ %zd", [[challenge protectionSpace] authenticationMethod], (ssize_t) [challenge previousFailureCount]);
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]){
[[challenge sender]useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
[[challenge sender]continueWithoutCredentialForAuthenticationChallenge: challenge];
}
}- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace{
return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}
