Thanks in advance 回答1: As MKPinAnnotationView is a subclass of UIView I believe you can explicitly set its frame. As an alternative you can apply CGAffineTransform to your view to scale it appropriately. pinView.transform = CGAffineTransformMakeScale(2.0, 2.0); 回答2: Just change the size of the frame

问题 I'm trying to create annotations on the MapKit from a geoJSON file, but the problem is that the coordinates provided by the geoJSON file don't match the coordinate system that MapKit uses. Question : How do I convert read the geoJSON file and convert the coordinates from `` to WGS84S ? Here is an example of what the geoJSON file looks like: {"name":"MAPADDRESSPOINT","type":"FeatureCollection" ,"crs":{"type":"name","properties":{"name":"EPSG:3008"}} ,"features":[ {"type":"Feature","geometry":{

问题 in the implementations class charged of displaying PINS, i have reserved two variables (title and sub title), in this example, only the word USA (the title) is displayed when i click on the PIN.

问题 Here is my setup: ViewController -> SecondViewControoler Three Goals: Add image to custom annotation (see code below) I have a subclass named "Capital", I would like to add the image in #1 and then create additional variables to hold values that will be passed to a new SecondViewController that includes (2) labels and a Picker View: for example label1 = "text1", label2 = "text2", and then grab a string from an array that contains multiple objects (i.e. the title for each row of the Picker)

问题 I'm trying to add a UILabel to an MKAnnotationView as a leftCalloutAccessoryView right after a pin got selected for the first time in the MKMapView. Adding the label is not a problem: The callout gets selected and opens, and this is when I add the label to the callout view. The callout gets automatically expanded to the left with a slide animation, and the new label including 2 lines is shown. Unfortunately I need to add the label after the Pin got selected because I need certain information
