我想从xib
创建一个自定义CalloutView
。我创建了一个xib和自定义AnnotationView
类。我想使用我的MapViewController
segue,其名称为showDetail
segue,因为此segue是Pushsegue。当用户点击我的calloutView中的按钮时,它应该执行我的showDetail
分段。
我搜索了所有文档、教程、指南和问题,但我可以使用Swift找不到任何解决方案。也没有自定义库。我已经三天找不到任何解决方案了。
我的CalloutView.xib
文件View
是我的CustomAnnotationView,名称为CalloutAnnotationView.swift
,文件的所有者为MapViewController
,它允许我使用MapViewController
段。
有我的CalloutAnnotationView.swift
override func hitTest(point: CGPoint, withEvent event: UIEvent?) -> UIView? {
let hitView = super.hitTest(point, withEvent: event)
if (hitView != nil) {
self.superview?.bringSubviewToFront(self)
}
return hitView
}
override func pointInside(point: CGPoint, withEvent event: UIEvent?) -> Bool {
let rect = self.bounds
var isInside = CGRectContainsPoint(rect, point)
if (!isInside) {
for view in self.subviews {
isInside = CGRectContainsPoint(view.frame, point)
if (isInside) {
}
}
}
return isInside
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
let calloutViewController = MapViewController(nibName: "CalloutView", bundle: nil)
if selected {
calloutViewController.view.clipsToBounds = true
calloutViewController.view.layer.cornerRadius = 10
calloutViewController.view.center = CGPointMake(self.bounds.size.width * 0.5, -calloutViewController.view.bounds.size.height * 0.5)
self.addSubview(calloutViewController.view)
} else {
// Dismiss View
calloutViewController.view.removeFromSuperview()
}
}
我的MapViewController.swift
代码;
// MARK: - MapKit Delegate Methods
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if let annotation = annotation as? Veterinary { // Checking annotations is not User Location.
var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(Constants.MapViewAnnotationViewReuseIdentifier) as? CalloutAnnotationView
if pinView == nil { // If it is nil it created new Pin View
pinView = CalloutAnnotationView(annotation: annotation, reuseIdentifier: Constants.MapViewAnnotationViewReuseIdentifier)
pinView?.canShowCallout = false
} else { pinView?.annotation = annotation } // If it is NOT nil it uses old annotations.
// Checking pin colors from Veterinary Class PinColor Method
pinView?.image = annotation.pinColors()
//pinView?.rightCalloutAccessoryView = UIButton(type: .DetailDisclosure)
return pinView
}
return nil
}
这些代码可以很好地加载我的xib文件。我从按钮创建了IBAction
,它使用showDetail
分段执行从MapViewController
到我的DetailViewController
的分段但问题是它没有从superview
中删除我的customCalloutView,所以我不能取消调用视图。
我该如何解决这个问题,或者创建自定义calloutView
以使用我的MapViewController
推送分段的最佳方法是什么?
非常感谢
在您的MKMapView代理中,查看在分割时是否调用了该代理
func mapView(mapView: MKMapView, didDeselectAnnotationView view: MKAnnotationView) {
if let annotation = view.annotation as? Veterinary {
mapView.removeAnnotation(annotation)
}
}
我希望这能帮助您解决问题
func mapView(mapView: MKMapView, didDeselectAnnotationView view: MKAnnotationView) {
if view.isKindOfClass(AnnotationView)
{
for subview in view.subviews
{
subview.removeFromSuperview()
}
}
}
