具有自定义高度的问题制作工具栏 |斯威夫特 5.

Question

本质上，我有以下工具栏，当前设置为在左侧和右侧包含两个按钮：

//Select All Toolbar
self.navigationController?.isToolbarHidden = false
self.navigationController?.toolbar.barTintColor = UIColor(named: "tabBarColor")
//self.navigationController?.toolbar.barTintColor = UIColor.white
self.navigationController?.toolbar.sizeToFit() // without this line it doesn't work
self.navigationController?.toolbar.tintColor = UIColor(named:"toolBarRedColor")
var items = [UIBarButtonItem]()
let selectbutton = UIBarButtonItem(title: "Left Button", style: .plain, target: self, action: #selector(printMe))
let unselectbutton = UIBarButtonItem(title: "Right Button", style: .plain, target: self, action: #selector(printMe))
items.append(selectbutton)
items.append( UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: self, action: nil))
items.append(unselectbutton)
self.toolbarItems = items

我想扩大工具栏的高度，并尝试执行以下操作：

class CustomToolbar: UIToolbar {
override func sizeThatFits(_ size: CGSize) -> CGSize {
var newSize: CGSize = super.sizeThatFits(size)
newSize.height = 80  // there to set your toolbar height
return newSize
}
}

什么做得不正确？未调整高度。

试试这个：

let navBarSize = CGSize(width: navigationController!.navigationBar.bounds.width, height: 200)
override func viewDidLayoutSubviews() {
navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: navBarSize.width, height: navBarSize.height)
}

希望这对:)有所帮助
