iOS 14 中 UITableView 标题布局中的 UISearchBar 问题 [英] UISearchBar in UITableView header layout issue in iOS 14

问题描述

我在 tableview 标题中使用带有搜索栏的新 UISearchController.在纵向模式下一切正常，但是当我旋转到横向并且 uisearchbar 开始编辑它的框架时，它的框架超出了屏幕，剪掉了取消按钮.我创建搜索控制器的代码

tableView.tableHeaderView = searchController.searchBar

这是我的示例代码

当旋转回uisearchbar的纵向布局时仍然不正确如果我使用 UITableviewController 没有问题，但我必须使用 uitableview 来实现.iOS 14 中是否缺少任何设置?

注意:我必须使用 tableHeaderView 而不是 navigationItem.searchController = searchController

解决方案

尝试在相应的 UIViewController 方法中调整 viewWillTransition 方法中的搜索栏框架.viewWillTransition 每次在旋转期间都会被调用，使您可以在 UIViewController 旋转期间更改布局.

这是示例代码:

 override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {coordinator.animate(withsideTransition: { (UIViewControllerTransitionCoordinatorContext) -> Void in调整搜索栏框架()}, 完成: { (UIViewControllerTransitionCoordinatorContext) ->作废})super.viewWillTransition(to: size, with: coordinator)}

I am using the new UISearchController with searchbar inside tableview header.Everything works fine in portrait orientation but when I rotate to landscape and uisearchbar start editing its frame is out of screen,clipping the cancel button. my code for creating searchcontroller

tableView.tableHeaderView = searchController.searchBar

Here is my sample code UISearchController sample

Rotation has no frame issue in landscape but only when uisearchbar starts editing [

When rotate back to portrait layout of uisearchbar is still incorrect There is no issue if I use UITableviewController but I have to implement with uitableview.Is there any setting I am missing in iOS 14 ?

Note:I have to use tableHeaderView not navigationItem.searchController = searchController

解决方案

Try adjusting the frame of search bar in viewWillTransition method that in your corresponding UIViewController . viewWillTransition is called every time during rotation and enables you to change layout during rotation of your UIViewController.

here is example code:

    override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    coordinator.animate( alongsideTransition: { (UIViewControllerTransitionCoordinatorContext) -> Void in
        adjustSearchbarFrame()
    }, completion: { (UIViewControllerTransitionCoordinatorContext) -> Void in
    })
    super.viewWillTransition(to: size, with: coordinator)
}
