【问题描述】:
我遇到了一个奇怪的问题,当我的应用首次加载时,无论您点击多少次都无法在搜索栏中输入文本,搜索栏嵌套在导航栏中。
我的应用也使用标签栏,当您切换标签然后返回到带有搜索栏的标签时,它允许您输入文本...任何想法是什么原因造成的?
搜索栏的代码如下:
func setupSearchBar(){
let locationSearchTable = storyboard!.instantiateViewController(withIdentifier: "LocationSearchTable") as! LocationSearchTableViewController
resultSearchController = UISearchController(searchResultsController: locationSearchTable)
resultSearchController?.searchResultsUpdater = locationSearchTable
searchBar = resultSearchController!.searchBar
searchBar.sizeToFit()
searchBar.placeholder = "Location"
searchBar.isTranslucent = true
searchBar.isUserInteractionEnabled = true
for subView in searchBar.subviews{
for subsubView in subView.subviews{
if let textField = subsubView as? UITextField{
var currentTextFieldBounds = textField.bounds
currentTextFieldBounds.size.height = 40.0
textField.bounds = currentTextFieldBounds
textField.borderStyle = UITextBorderStyle.none
textField.textAlignment = NSTextAlignment.left
textField.font = UIFont(name: "System", size: 25.0)
textField.textColor = theme?.textColour
}
}
}
self.navigationController?.navigationBar.setBarColour(colour: (theme?.tabBarColour)!, tint: (theme?.textColour)!)
navigationItem.titleView = resultSearchController?.searchBar
navigationItem.titleView?.bringSubview(toFront: (resultSearchController?.searchBar)!)
searchBar.delegate = self
searchBar.showsSearchResultsButton = true
searchBar.setImage(#imageLiteral(resourceName: "location_icon.png"), for: UISearchBarIcon.resultsList, state: UIControlState.normal)
resultSearchController?.hidesNavigationBarDuringPresentation = false
resultSearchController?.dimsBackgroundDuringPresentation = true
definesPresentationContext = true
locationSearchTable.mapView = mapView
locationSearchTable.handleMapSearchDelegate = self
}
【问题讨论】:
-
“无法输入文本”是什么意思,键盘没有显示或者您无法在文本框中输入任何内容?
-
键盘根本不显示。只有在您更改了选项卡之后。稍后我会发布一些代码,我现在不在家。
-
请添加屏幕截图和更多信息...不难发现问题
-
屏幕截图无济于事,您点击搜索栏输入文字,没有任何反应。我已经尝试过 isUserInteractionEnabled、zPositions 和 layoutsubviews 等,但没有任何效果。
-
你在真 iPhone 上试过了吗?因为模拟器有时会在它应该显示的时候不显示键盘
