我是Swift和Stackoverflow的新手,我想知道是否有办法将数据从我的plist导入到detailCalloutAccesoryView,方法与导入到&#34; title&#34;相同。和&#34;副标题&#34;在我的地图注释标注?这样,我就可以避免使用我自己的自定义地图注释,而是使用MapKit的内置功能。</ p>
我将变量称为标题和副标题,如下所示:
var myData: NSArray?
if let path = NSBundle.mainBundle().pathForResource("myData", ofType: "plist") {
myData = NSArray(contentsOfFile: path)
}
if let items = myData {
for item in items {
let lat = item.valueForKey("Latitude") as! Double
let long = item.valueForKey("Longitude") as! Double
let myAnnotation = Mydata(value1: "Value1", value2: "Value2", value3: "Value3", latitude: lat, longitude: long)
// Define "Value1 to be shown as title in Callout
myAnnotation = item.valueForKey("Value1") as? String
// Define "Value2 to be shown as subtitle in Callout
myAnnotation.subtitle = item.valueForKey("Value2") as? String
annotations.append(myAnnotation)
}
}
return annotations
}
到目前为止,我只是在使用以下代码的字幕位置的detailCalloutAccessoryView的所有注释中显示相同的值:
let detailAccessory = UILabel(frame: CGRectMake(0,0,50,30))
detailAccessory.text = "Value3" // Obviously, shows constant value for all annotations
detailAccessory.font = UIFont(name: "Verdana", size: 10)
pinView?.detailCalloutAccessoryView = detailAccessory
拜托,不要让我的无知惹恼你......
答案 0 :(得分:1)
您需要实现func mapView(mapView:MKMapView,viewForAnnotation annotation:MKAnnotation) - &gt; MKAnnotationView?委托方法。在那里你可以自定义detailCalloutAccessoryView。
