ios - 导航 Controller 中的 UISearchBar 和两个按钮
<p><p>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</p>
<pre><code> 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()
</code></pre></p>

<p><p>请检查:</p>
<pre><code>override func viewWillLayoutSubviews() {
searchController?.searchBar.frame = CGRect(x: 0, y: 0, width: 300, height: 30)
searchController?.searchBar.sizeToFit()
}
</code></pre></p>
