UISearchBarsearchButton をクリックすると読み込まれる があります。したがって、メソッドfunc searchBarSearchButtonClicked(searchBar: UISearchBar)とfunc searchBarCancelButtonClicked(searchBar: UISearchBar)デリゲート メソッドがあります。ただし、問題は、a が埋め込まれた別のビュー コントローラーUINavigationControllerに移動し、検索バーのあるページに戻って検索ボタンをクリックすると、タイトル ビュー全体が表示されないことです。現在、私のコードは次のとおりです。
func searchbarPopulate() {
tempSearchBar = searchButton
searchBar2.delegate = self
searchBar2.searchBarStyle = UISearchBarStyle.Minimal
searchBar2.showsCancelButton = true
}
@IBAction func tapSearchButon(sender: AnyObject) {
self.viewDidLoad()
searchbarPopulate()
self.navigationItem.rightBarButtonItem = nil
navigationItem.titleView = searchBar2
searchBar2.alpha = 0
navigationItem.setLeftBarButtonItem(nil, animated: true)
UIView.animateWithDuration(0.5, animations: {
// self.searchBar2.alpha = 1
}, completion: { finished in
self.searchBar2 .becomeFirstResponder()
self.searchBar2.alpha = 1
})
}
func searchBarSearchButtonClicked(searchBar: UISearchBar) {
attractionsMap.removeAnnotations(attractionsMap.annotations);
performYelpSearch(searchBar.text)
searchBarCancelButtonClicked(searchBar)
}
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
UIView.animateWithDuration(0.5, animations: { () -> Void in
searchBar.alpha = 0
}) { (completed) -> Void in
// self.navigationItem.titleView = "Attractions"
// Make Title View of Attractions in Sketch
self.navigationItem.rightBarButtonItem = self.searchButton
}
}
これは、ピンの注釈がタップされ、アトラクションの詳細 VC にセグエされたときです。
func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!, calloutAccessoryControlTapped control: UIControl!) {
if (control == view.rightCalloutAccessoryView) {
let selectedLocation = view.annotation;
let selectedCoordinate = view.annotation.coordinate;
var latitude = selectedCoordinate.latitude
var longitude = selectedCoordinate.longitude
var location:CLLocation = CLLocation(latitude: latitude, longitude: longitude)
let businessPlacemark = MKPlacemark(coordinate: selectedCoordinate, addressDictionary: nil)
indicatedMapItem = selectedCoordinate;
let resturantMock:Resturant = Resturant(dictionary: resultQueryDictionary)
let dataArray = resultQueryDictionary["businesses"] as! NSArray
var foundDisplayAddress:String = "Address not found"
for business in dataArray {
let obj = business as! NSDictionary
var yelpBusinessMock: YelpBusiness = YelpBusiness(dictionary: obj)
if yelpBusinessMock.latitude == view.annotation.coordinate.latitude {
if yelpBusinessMock.longitude == view.annotation.coordinate.longitude {
attractionDict = obj;
foundDisplayAddress = yelpBusinessMock.displayAddress
businessMock = Business(dictionary: obj)
}
}
}
attractionLocationString = foundDisplayAddress
performSegueWithIdentifier("attractionToDetail", sender: view);
}
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "attractionToDetail" {
if let annotation = (sender as? MKAnnotationView)?.annotation {
if let ivc = segue.destinationViewController as? AttractionsDetailViewController {
searchBarCancelButtonClicked(searchBar2)
ivc.attractionLocation = self.indicatedMapItem
ivc.attractionDetailAddressString = self.attractionLocationString
ivc.currentBusiness = self.attractionDict
ivc.businessToUse = self.businessMock
}
}
}
