mkmapview

问题 I've been playing around with the MKMapView and trying get my head around how the MKMapViewDelegate system works. So far I have no luck in getting the didAddAnnotationViews to get called when the current location marker is added. I have set my app delegate to implement MKMapViewDelegate, I have an Outlet to the MapView in my xib and have set the delegate property of the MapView to be self, as in the app delegate instance. I have implemented didAddAnnotationViews in the app delegate which I

问题 My problem is simple: I'm waiting to take a screenshot of an MKMapView, and I want to do it only once the map is loaded. Unfortunately, this delegate method is almost always called before the map is actually loaded. I just get a grid, or a few loaded tiles if I'm lucky. Is there a good way to do what I need to do? Or am I missing something in the MKMapViewDelegate protocol? Thanks! 回答1: Perhaps you could try adding a timer and then take the screenshot in the completion block of the timer. Or

问题 I'd want to move the Legal label to the right side. On iOS 6 and 7 the below solution was working fine, however on iOS 8.3 it seems to not work. I get the label, then with a timer (0.1 sec) in viewDidLayoutSubviews I call this method : -(void)moveLegalLabel { UIView * legalLink = [self attributionView]; legalLink.frame = CGRectMake(self.mapView.frame.size.width - legalLink.frame.size.width - 10, self.mapView.frame.size.height - legalLink.frame.size.height - 10 , legalLink.frame.size.width,

问题 I need to find a way to change the pin color when the map is loaded by pushing a button from another screen. For example, the original pins are all red, but when I go to a page and push the map button, it has to lead me to the map view and the coordinates of that location have to be marked with a green pin. I already have the map set up and the setup of making the pins all red. Any help is appreciated. So, just a recap: Page with map with red pin --> click pin, click annotation (another view

问题 I am trying to add a custom value to my MKAnnotation. I would like to have it store the unique ID of the location. My code for setting up the annotation with a title and subtitle works like this: location.latitude = [dictionary[@"placeLatitude"] doubleValue]; location.longitude = [dictionary[@"placeLongitude"] doubleValue]; newAnnotation = [[MapViewAnnotation alloc] initWithTitle:dictionary[@"placeName"] andCoordinate:location]; newAnnotation.subtitle = dictionary[@"placeCity"]; How would I

问题 I'm looking to add Streetview function to my current iphone app maps I made with MKMapView. Any idea how to do this? Thx for helping, Stephane 回答1: Unless you want to spend a long time mapping tiles onto a 3D world, you can give a link to the maps app, which lets the user choose Street View. If you want an easy way to embed Street View, use the (fairly new) Street View Image API, which returns static images for a location and heading (relative to the road): http://maps.googleapis.com/maps/api

问题 I've got two custom annotation classes for my map: one for a single post tied to a location, and one for a cluster of those posts. The cluster stores pointers to all of the posts it contains, as well as a central lat/long location (calculated using the locations of the posts it contains). I have the behaviour that when I click on a cluster annotation it removes the cluster and adds its posts to the map. What I want is to change the pin-drop annotation when expanding the clusters to an
