- 出现三个小蓝点
- 在navigationViewController 的rootViewController中使用侧滑手势后，push，出现卡顿现象。按下home键，在进入就会跳转到push的界面。
class BaseNavigationVC: UINavigationController,UINavigationControllerDelegate{
var popGestureDelegate: UIGestureRecognizerDelegate?
override func viewDidLoad() {
super.viewDidLoad()
self.popGestureDelegate = self.interactivePopGestureRecognizer?.delegate
self.delegate = self
}
//MARK: - push事件拦截
override func pushViewController(_ viewController: UIViewController, animated: Bool) {
// 去除手势蓝点
viewController.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .done, target: nil, action: nil)
if childViewControllers.count > 0 {
viewController.hidesBottomBarWhenPushed = true
}
super.pushViewController(viewController, animated: animated)
}
//MARK: - 导航栏试图完全显示
func navigationController(_ navigationController: UINavigationController, didShow viewController: UIViewController, animated: Bool) {
if viewController == self.viewControllers[0] { //rootVC禁止侧滑
self.interactivePopGestureRecognizer!.delegate = self.popGestureDelegate
}
else { //清空滑动返回手势的代理就能实现滑动返回功能
self.interactivePopGestureRecognizer!.delegate = nil
}
}
}
