swift - 指定VC隐藏导航栏 - 禁用tabbar的根控制器手势,防止两个tabbar跳转 手势冲突

1. viewdidload 设置代理

self.navigationController?.delegate = self

  

2.代理里面指定VC 隐藏

//MARK: - 导航栏delegate
extension JYHomeViewController:UINavigationControllerDelegate { /// 此方法会在controller的viewWillApper方法调用后开始调用(使用时注意controller的生命周期)
func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
if viewController is JYHomeViewController || viewController is JYPhotoBrowserController || viewController is JYRTSRootViewController {
JY_WINDOW?.removeBubbleView()
self.navigationController?.setNavigationBarHidden(true, animated: true)
}else{
self.navigationController?.setNavigationBarHidden(false, animated: true)
}
}
}

  
3. 在根控制器首页 禁用手势, 不管有几个 homeVc, 有俩tabbar 就在俩homeVc都写上

extension JYHomeViewController: UIGestureRecognizerDelegate {
/// 禁止使用手势返回
func forbidhenSideBack() {
self.isCanSideBack = false
if (self.navigationController?.responds(to:#selector(getter: self.navigationController?.interactivePopGestureRecognizer))) == true {
self.navigationController?.interactivePopGestureRecognizer?.delegate = self
}
}
/// 恢复手势返回
func resetSideBack() {
self.isCanSideBack = true
if (self.navigationController?.responds(to:#selector(getter: self.navigationController?.interactivePopGestureRecognizer))) == true {
self.navigationController?.interactivePopGestureRecognizer?.delegate = nil
}
}
func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
return self.isCanSideBack
}
}

  在 willappear 和willDisaapper 使用

    override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.forbidhenSideBack()
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
self.resetSideBack()
}
