我如何隐藏导航栏从第一个ViewController或一个特定的ViewController在swift?
我在viewDidLoad()中使用了以下代码:
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.isNavigationBarHidden = true
}
以及viewWillAppear:
override func viewWillAppear(animated: Bool) {
self.navigationController?.isNavigationBarHidden = true
}
这两种方法都对所有viewcontroller隐藏导航控制器。
当前回答
想在第一个视图控制器上隐藏导航栏
override func viewWillAppear(animated: Bool) {
self.navigationController?.isNavigationBarHidden = true
}
想在第二个视图控制器上显示导航栏
override func viewWillAppear(animated: Bool) {
self.navigationController?.isNavigationBarHidden = false
}
其他回答
/*. Swift 5 */
let controller = self.storyboard?.instantiateViewController(withIdentifier: "sc_userNavigation") as! UserNavigationViewController
let navigationController = UINavigationController(rootViewController: controller)
navigationController.setNavigationBarHidden(true, animated: false)
navigationController.modalPresentationStyle = .fullScreen
self.present(navigationController, animated: false, completion: nil)
你可以在viewWillDisappear中取消隐藏navigationController
override func viewWillDisappear(animated: Bool)
{
super.viewWillDisappear(animated)
self.navigationController?.isNavigationBarHidden = false
}
斯威夫特3
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
self.navigationController?.setNavigationBarHidden(false, animated: animated)
}
你可以从窗口控制器(Swift3)来做
class WindowController: NSWindowController {
override func windowDidLoad() {
super.windowDidLoad()
window?.titleVisibility = .hidden
}
}

override func viewWillAppear(animated: Bool) {

override func viewWillAppear(animated: Bool) {

}
在Swift中显示导航栏的方法:
self.navigationController?.setNavigationBarHidden(false, animated: true)
self.navigationController?.navigationBar.isHidden = false
self.navigationController?.isNavigationBarHidden = false
