我想从CalloutView
创建自定义xib
。我创建了一个xib和自定义AnnotationView
类。我想使用名称为MapViewController
segue的showDetail
segue,因为此segue是Push segue。当用户在我的calloutView中点击按钮时,它应该执行我的showDetail
设置。
我搜索了所有文档,教程,指南和问题,但我可以
用Swift无法找到任何解决方案。也没有自定义库。到3天为止,我找不到任何解决方案。
我的CalloutView.xib
文件View
是我的CustomAnnotationView,其名称为CalloutAnnotationView.swift
,文件的所有者为MapViewController
,它允许我使用MapViewController
segues。
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。我从一个按钮创建了
IBAction
,并使用MapViewController
进行了从DetailViewController
到我的showDetail
的选择。但是问题是它不会从superview
中删除我的customCalloutView,所以我无法关闭标注视图。如何解决此问题,或者创建用于使用我的
calloutView
推式segue的自定义MapViewController
的最佳方法是什么?非常感谢你。
最佳答案
在您的MKMapView委托中,查看是否在调用时调用了此方法:
func mapView(mapView: MKMapView, didDeselectAnnotationView view: MKAnnotationView) {
if let annotation = view.annotation as? Veterinary {
mapView.removeAnnotation(annotation)
}
}
