問題が発生しましたpushViewController

Question

最近、私は次のviewControllerにpushViewControllerを押したときに奇妙な問題が発生しました。 なぜそれは奇妙な質問だと思いますか？必ずしも現れるとは限りません（発生確率は低い）。表示されたら、次のviewControllerは画面上のナビゲーションバーのみを表示しますが、私はまだrootViewControllerを見ることができますが、反応なしでそれに触れます（PopGestureは有効です）。

- (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

私はあなたが

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

と同じポップ

[super popViewControllerAnimated:animated]; 

に

[super pushViewController:viewController animated:animated]; 

を変更すべきだと思います

[self.navigationController popViewControllerAnimated:animated]; 

Answer 2

に私はXcodeののキャッシュをクリアし、この場合は表示されません。たぶん私はこのケースを引き起こした3番目のlibをインポートしました。しかし、私が尋ねたように、必ずしも現れるとは限りません（発生確率は低い）。それで、それがうまくいったことを願って。
