mkmapview

Hey guys, I'm building an iPhone app for my company and in one of the sections I want to create a tab bar item where it pin point the location of my company. So far I built a basic map view, but I haven't figured what would the code be for pin pointing the location of my company. hope someone can help, thanks Did you try investigating MapCallouts from Apple Sample Code? http://developer.apple.com/library/ios/#samplecode/MapCallouts/Introduction/Intro.html 来源： https://stackoverflow.com/questions/5067817/how-to-pin-point-location-in-google-map-in-xcode

I am working on the map application and as per requirement i need to show a single pin for a single region even if it has multiple user coordinates when its completely zoomed out but when its zoomed in to the map then i should display all the pins as per its coordinates. I have given example below to explain my problem. I have city New York on this city I have 100 pins on my mapview when I am zooming out of my map it should show me only one annotation pin on the place of 100 pins but when I am zooming in then it should show again 100 pin on map. Does any one knows about this. I need suggestion

I have an array of annotations.I am calculating the distance between each annotation from user location.What I want to know is, how can I find lets say 3 nearest annotations from these distances? Here is how I am calculating distance from user location to annotations. CLLocation *userLocation = self.mapView.userLocation.location; for (Annotation *obj in annotations) { CLLocation *loc = [[CLLocation alloc] initWithLatitude:obj.coordinate.latitude longitude:obj.coordinate.longitude]; // CLLocation *userLocation = [[CLLocation alloc] initWithLatitude:self.mapView.userLocation.coordinate.latitude

I have a MKMapView with some annotations in it. Now, every time when the region changes I load new annotations. That works fine, but if some annotation is near border of the map view and you tap on it, the annotation info window pops out and the mkmapview region moves a little (so that it can show the window nicely), but the problem is that also the regionDidChangeAnimated is called and it reloads all my annotations and of course hides the info window. I know you can just tap the annotation once again when it's reloaded but for user it seems broken and also you reload annotations when you don

So i have a UIScrollView with UIPageControl which has a bunch of MKMapViews (mostly 15 different maps). The app is really sluggish once this view loads and after a few minutes of usage i get a memory warning. I looked at it in Instruments and the maps take an insanely high chunk of memory. Even upto ~200mb sometimes. One thing i can think of is to reuse the mapViews. But because of how the views are structured the coding complexity increases. Any suggestions how i can improve performance? This is how my app is structured: I have a view controller which has a UIScrollView which i use for

I have an app to which I display routes on a map as MKPolyline. I made my search but I was unable to find a sample code on how to display custom MKPolyline callouts as Apple does on the ios6 maps: Can some help me? Thank you in advance..
