iOS导航栏中的SearchBar在触摸时会稍微向下移动

Question

我在Google Place AutoComplete的导航栏中放置了一个搜索栏。当它出现时，它会很好地显示，但是当您在其中轻按时，它会稍微向下移动并停留在该位置，即使您单击“取消”也是如此，直到将titleView设置为nil然后再次返回，然后重置。这是在我的viewDidLoad方法中调用的相关代码：

resultsViewController = GMSAutocompleteResultsViewController()
    resultsViewController?.delegate = self

    searchController = UISearchController(searchResultsController: resultsViewController)
    searchController?.searchResultsUpdater = resultsViewController
    searchController?.searchBar.sizeToFit()
    searchController?.hidesNavigationBarDuringPresentation = false
    definesPresentationContext = true
    navigationController?.navigationBar.isTranslucent = true
    searchController?.hidesNavigationBarDuringPresentation = false
    navigationItem.titleView = nil

然后在需要时将其设置如下：

navigationItem.titleView = searchController?.searchBar

Answer 1

尝试：

    searchController.searchBar.frame = CGRect(center: CGPoint(x: 15,y: 10), size: CGSize(width: 30, height: 30))
    let vu = UIView(frame: CGRect(center: .zero, size: CGSize(width: self.view.frame.width - 10, height: 40)))

    vu.addSubview(searchController.searchBar)
    vu.backgroundColor = UIColor.clear

    navigationItem.titleView = vu

  

根据您的需要设置框架
