问题 I am trying to change the pin colour from the default red to a custom image but whatever I am trying just isn't working. I have downloaded the sample code from this website: http://icodeblog.com/2009/12/21/introduction-to-mapkit-in-iphone-os-3-0/ The code works on it's own but when I import the annotation classes into my code, they do not work and I have no idea why.

问题 I tried to make the callout work but that didn't happen as I did something wrong in my prepare for segue.

问题 I'm new on Swift Programming, and I'm trying to build an app that I can get the coordinates of the center of the view with MapKit and Swift 2. I already can get the current location, but I need if I move on the map, the location set to the new point which will be the center of the screen. Can you help me with this please?.

问题 How do I make it possible, using MapKit in Swift, for the user to drag an annotation from one position to another within the map? I have set the annotation view to be draggable, when my map view delegate creates the annotation view, like this: func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? { var v : MKAnnotationView! = nil if annotation is MyAnnotation { let ident = "bike" v = mapView.dequeueReusableAnnotationView(withIdentifier:ident) if v == nil {

问题 My App Has to integrate search location names using text box. Is Map kit has any method to implement this kind of a functionality ? This below image displays what i exactly need 回答1: No , there is not any method of MapKit to implement this type of property..

It's super simple, just put in some code like this. UITapGestureRecognizer* tapRec =

问题 I have a map view with pins that when the user selects a pin it goes to a detail screen for that pin. I also have a table view that when the user selects an item it goes to the same type detail view. Here's the problem ... It seems to work fine in everything from 3.1.3 to 4.1. That is the detail view matches with the pin. But I have a user who just upgraded to iOS 4.2 and says that under 4.1 it worked fine, but in 4.2 the pin selection takes him to the detail for a different pin. But in the

问题 I am trying to use the new iOS7 MKMapSnapshotter to generate a static map image. Whenever my app needs a map, I call the following: MKMapSnapshotter *snapshotter = [[[MKMapSnapshotter alloc] initWithOptions:theOptions] autorelease]; dispatch_queue_t aQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0); DebugLog(@"Snapshotter allocated %@ and run on queue %@", snapshotter, aQueue); [snapshotter startWithQueue:aQueue completionHandler:^(MKMapSnapshot *snapshot, NSError
