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
在Swift中隐藏导航栏的方法:
self.navigationController?.setNavigationBarHidden(true, animated: true)
self.navigationController?.navigationBar.isHidden = true
self.navigationController?.isNavigationBarHidden = true
其他回答
在Swift中隐藏导航栏的方法:
self.navigationController?.setNavigationBarHidden(true, animated: true)
self.navigationController?.navigationBar.isHidden = true
self.navigationController?.isNavigationBarHidden = true
你可以从窗口控制器(Swift3)来做
class WindowController: NSWindowController {
override func windowDidLoad() {
super.windowDidLoad()
window?.titleVisibility = .hidden
}
}
private func setupView() {
view.backgroundColor = .white
navigationController?.setNavigationBarHidden(true, animated: false)
}
替代
在viewDidLoad中使用此设置
title = "Madman"
navigationController?.isNavigationBarHidden = false
navigationController?.navigationBar.prefersLargeTitles = true
navigationItem.largeTitleDisplayMode = .always
检查Collectionview, scrollview或tableView的约束
NSLayoutConstraint.activate([
tableView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor),
tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor)
])
在IOS 8中这样做
navigationController?.hidesBarsOnTap = true
但只有当它是UINavigationController的一部分时
当你想要回它时，把它设为false
如果您知道所有其他视图都应该有可见的条，您可以使用viewWillDisappear将它再次设置为可见。
迅速:
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
navigationController?.setNavigationBarHidden(true, animated: animated)
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
navigationController?.setNavigationBarHidden(false, animated: animated)
}
