第三方登陆调用- (void)sendAuthRequestWithController:(UIViewController*)viewController

                             delegate:(id<WXAuthDelegate>)delegate {

    SendAuthReq* req = [[SendAuthReq alloc] init];

    req.scope = @"snsapi_userinfo";

    self.authState = req.state =  @"snsapi_userinfo";

    self.delegate = delegate;

    [WXApi sendAuthReq:req viewController:viewController delegate:self];

}

之后卡斯：Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[WXApi sendAuthReq:viewController:delegate:]: unrecognized selector sent to class 0x104da0688'

已经检查其他配置无错误，之前集成拉起小程序无错误！
