我们可以使用新的BottomNavigationBar作为临时小吃吧吗？

Question

我知道Snackbar即将推出，＆＃34;但与此同时，使用BottomNavigationBar是否安全？

Answer 1

我不会将BottomNavigationBar（现在是BottomTabBar）用作Snackbar，因为它没有提供您想要的正确布局。我在开发中添加了一个示例项目 - ＆gt;程序化调用ControlView，它将向您展示如何使用ControlView类创建Snackbar。顺便说一下，ControlView是SearchBar和Toolbar的父类，它将成为Snackbar创建的基础。这是UIViewController代码。

class ViewController: UIViewController {
/// Reference for ControlView.
private var controlView: ControlView!

override func viewDidLoad() {
    super.viewDidLoad()
    prepareView()
    prepareControlView()
}

/// General preparation statements.
private func prepareView() {
    view.backgroundColor = MaterialColor.white
}

/// Prepares the controlView
private func prepareControlView() {
    controlView = ControlView(frame: CGRectMake(0, view.bounds.height - 56, view.bounds.width, 56))

    // Undo button.
    let undoButton: FlatButton = FlatButton()
    undoButton.pulseScale = false
    undoButton.pulseColor = MaterialColor.white
    undoButton.setTitle("UNDO", forState: .Normal)
    undoButton.setTitleColor(MaterialColor.teal.accent1, forState: .Normal)

    let label: UILabel = UILabel()
    label.text = "Archived"
    label.textColor = MaterialColor.white

    controlView.backgroundColor = MaterialColor.grey.darken4
    controlView.contentView.addSubview(label)
    controlView.rightControls = [undoButton]
    controlView.contentInsetPreset = .WideRectangle3

    view.addSubview(controlView)
    controlView.contentView.grid.views = [label]
}
}
