可以看下侧滑后App上会覆盖一层View,这是导致卡死的根本原因.以下为处理方法.禁止侧滑返回即可解决,个人认为是苹果的bug
Swift 和OC代码如下

   // 禁用系统侧滑返回手势
- (void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = NO;
    }
}

    // 重新启用系统侧滑返回手势
- (void)viewDidDisappear:(BOOL)animated {
    [super viewDidDisappear:animated];
    if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        self.navigationController.interactivePopGestureRecognizer.enabled = YES;
    }
}
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        // 禁用侧滑返回手势
        self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
    }

    override func viewDidDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        // 启用侧滑返回手势
        self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true
    }
