有没有办法创建多行注释?
这是我的代码:
1)我的customAnnotation类
import UIKit
import MapKit
class CustomAnnotation: NSObject, MKAnnotation {
var title: String?
var subtitle: String?
var address: String = ""
var phoneNumber: String = ""
var workingHours: String = ""
var coordinate: CLLocationCoordinate2D
init( title: String,
subtitle: String,
address: String,
phoneNumber: String,
workingHours: String,
coordinate: CLLocationCoordinate2D ){
self.title = title
self.subtitle = subtitle
self.address = address
self.phoneNumber = phoneNumber
self.workingHours = workingHours
self.coordinate = coordinate
super.init()
}
}
2)我的 View Controller 与 map :
MapViewController 类:UIViewController、MKMapViewDelegate {
@IBOutlet weak var theMapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
let latitude: CLLocationDegrees = 54.685290
let longitude : CLLocationDegrees = 25.279661
let latDelta : CLLocationDegrees = 0.2
let lonDelta : CLLocationDegrees = 0.2
let theSpan : MKCoordinateSpan = MKCoordinateSpanMake(latDelta, lonDelta)
let branchLocation : CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude, longitude)
let theRegion : MKCoordinateRegion = MKCoordinateRegionMake(branchLocation, theSpan)
let annotation = CustomAnnotation(title: "Brach1", subtitle: "some text for B1", address: "address str 12-12", phoneNumber: "123 321 123", workingHours: "00 - 24", coordinate: branchLocation)
self.theMapView.setRegion(theRegion, animated: true)
self.theMapView.addAnnotation(annotation)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
let identifier = "MyPin"
if annotation.isKindOfClass(MKUserLocation) {
return nil
}
var annotationView: MKPinAnnotationView? = mapView.dequeueReusableAnnotationViewWithIdentifier(identifier) as? MKPinAnnotationView
if annotationView == nil {
annotationView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
annotationView?.canShowCallout = true
let multiLineView = UIView(frame: CGRectMake(0, 0, 100, 40))
let label1 = UILabel(frame: CGRectMake(0,0,100,20))
label1.text = "Some text1"
multiLineView.addSubview(label1)
let label2 = UILabel(frame: CGRectMake(0,20,100,20))
label2.text = "some text2"
multiLineView.addSubview(label2)
annotationView!.rightCalloutAccessoryView = multiLineView
} else {
annotationView!.annotation = annotation
}
return annotationView
}
}
我得到了什么:
如果我会使用
annotationView!.leftCalloutAccessoryView = multiLineView
我会得到:
我还没有找到其他方法。我希望像bottomCaouttAccessoryView这样的东西得到类似的东西:
这对我来说非常重要,注释的高度不可修改。 (这就是为什么我的三个标签甚至不适合那里) 我试图使用注释 View 的自动调整大小方法,但没有运气:(
最佳答案
副标题是一个打印到单行标签的字符串,您可能必须创建一个子类才能添加多行。
