在我的应用程序中打开时,我需要帮助在GMSAutocompleteViewController的searchBar中设置文本.我在
Google Place AutocompleteViewController使用GMSAutocompleteViewController.
我通过结合@Youngjin和@ Exception的Swift 4和Google Places 2.6.0的答案得到了一个有效的解决方案
原文链接：https://www.f2er.com/swift/319290.html要访问GMSAutocompleteViewController搜索栏：
let views = gmsAutoCompleteViewController.view.subviews let subviewsOfSubview = views.first!.subviews let subOfNavTransitionView = subviewsOfSubview[1].subviews let subOfContentView = subOfNavTransitionView[2].subviews let searchBar = subOfContentView[0] as! UISearchBar
searchBar.text = "Your address" searchBar.delegate?.searchBar?(searchBar,textDidChange: "Your address") // This performs the automatic searching.
我发现在尝试从内部设置文本时收到了EXC_BAD_ACCESS错误
didRequestAutocompletePredictions(_ viewController：GMSAutocompleteViewController).
所以我把这段代码放在我提供autoCompleteController的完成块中,它可以正常工作.
将它们组合在一起：
let gmsAutoCompleteViewController = GMSAutocompleteViewController()
gmsAutoCompleteViewController.delegate = self
present(gmsAutoCompleteViewController,animated: true) {
let views = gmsAutoCompleteViewController.view.subviews
let subviewsOfSubview = views.first!.subviews
let subOfNavTransitionView = subviewsOfSubview[1].subviews
let subOfContentView = subOfNavTransitionView[2].subviews
let searchBar = subOfContentView[0] as! UISearchBar
searchBar.text = "Your address"
searchBar.delegate?.searchBar?(searchBar,textDidChange: "Your address")
}
编辑：我发现这个解决方案似乎只适用于iOS 11.让searchBar = subOfContentView [0]为！的UISearchBar将在iOS 10上失败,可能还会降低版本.
