我正在尝试向我的导航 Controller 添加两个按钮和一个 SearchBar,但对齐不正确。我已经尝试了几乎所有方法,例如更改 SearchBar、UIButton 的大小或更改 Y 定位,但没有奏效。知道如何解决这个问题吗? 我正在使用 iOS 11 和 Xcode 9
searchController = UISearchController(searchResultsController: nil)
searchController?.searchBar.frame = CGRect(x: 0, y: 0, width: 200, height: 30)
searchController?.delegate = self
searchController?.searchResultsUpdater = self
let refineButton = UIButton.init(type: UIButtonType.custom)
refineButton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
refineButton.setImage(#imageLiteral(resourceName: "settings-button"), for: UIControlState.normal)
refineButton.widthAnchor.constraint(equalToConstant: 30).isActive = true
refineButton.heightAnchor.constraint(equalToConstant: 30).isActive = true
let refineItem = UIBarButtonItem(customView: refineButton)
navigationItem.leftBarButtonItem = refineItem
navigationItem.titleView = searchController?.searchBar
searchController?.searchBar.sizeToFit()
请检查:
override func viewWillLayoutSubviews() {
searchController?.searchBar.frame = CGRect(x: 0, y: 0, width: 300, height: 30)
searchController?.searchBar.sizeToFit()
}
关于ios - 导航 Controller 中的 UISearchBar 和两个按钮,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/46383888/
