Question

最近，当我将pushConController推送到下一个viewController时，出现了一个奇怪的问题。为什么我认为这是一个奇怪的问题？因为它并不总是出现（发生的概率很低）。当它出现时，下一个viewController只在屏幕上显示其导航栏，我仍然可以看到rootViewController，但触摸它没有反应（PopGesture有效）。希望得到你的帮助，非常感谢。

#pragram mark - method of pushing   
- (void)clickToAccout {

    if (![self countTotalSelectedNumber]) {
        [SVProgressHUD showInfoWithStatus:@"没有被选择的商品"];
        return;
    }

    CSCreatOrderViewController *creatOrderVC = [[CSCreatOrderViewController alloc] init];
    creatOrderVC.totalPrice = [self countTotalPrice];
    creatOrderVC.goods = [self selectedGoods];

    [self.navigationController pushViewController:creatOrderVC animated:YES];
}

Answer 1

我认为你应该改变

[super pushViewController:viewController animated:animated];

到

[self.navigationController pushViewController:viewController animated:animated];

弹出时也一样

[super popViewControllerAnimated:animated];

到

[self.navigationController popViewControllerAnimated:animated];

Answer 2

我清除Xcode的缓存，这种情况不会出现。也许我导入第三个lib之前导致了这种情况。但就像我问的那样，它并不总是出现（发生概率很低）。所以，希望它一直很好。
