Giz*_*odo 3 xcode uinavigationbar ios swift uinavigationbarappearance
我试图Title在 a 中显示一个大的Navigation bar,但背景清晰。向上滚动时,它将Navigation bar具有模糊效果。
这看起来是正确的,但是,在滚动时,动画似乎被破坏了。此外,过渡有时会卡住:
我的代码如下:
UINavigationController:
override func viewDidLoad() {
super.viewDidLoad()
if #available(iOS 13.0, *) {
self.navigationBar.prefersLargeTitles = true
let style = UINavigationBarAppearance()
style.configureWithDefaultBackground()
style.titleTextAttributes = [.font: UIFont.systemFont(ofSize: 18)]
self.navigationBar.standardAppearance = style
self.navigationBar.compactAppearance = style
//Configure Large Style
let largeStyle = UINavigationBarAppearance()
largeStyle.configureWithTransparentBackground()
largeStyle.largeTitleTextAttributes = [.font: UIFont.systemFont(ofSize: 28)]
self.navigationBar.scrollEdgeAppearance = largeStyle
}
}

该UITableView是内部的UINavigationController。两者都是通过 segue 方式从故事板中提取的。
您可以尝试使用 UITableViewController 代替 UITableview。我试过使用 UITableViewController 并且它对我来说工作正常。请检查以下设计和代码。
class ViewController: UITableViewController
{
override func viewDidLoad() {
super.viewDidLoad()
if #available(iOS 13.0, *) {
self.navigationController?.navigationBar.prefersLargeTitles = true
let style = UINavigationBarAppearance()
style.configureWithDefaultBackground()
style.titleTextAttributes = [.font: UIFont.systemFont(ofSize: 18)]
self.navigationController?.navigationBar.standardAppearance = style
self.navigationController?.navigationBar.compactAppearance = style
//Configure Large Style
let largeStyle = UINavigationBarAppearance()
largeStyle.configureWithTransparentBackground()
largeStyle.largeTitleTextAttributes = [.font: UIFont.systemFont(ofSize: 28)]
self.navigationController?.navigationBar.scrollEdgeAppearance = largeStyle
}
self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")
// Do any additional setup after loading the view.
}
override func numberOfSections(in tableView: UITableView) -> Int {
1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
10
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
cell.textLabel?.text = "\(indexPath.row)"
return cell
}
}
