I want to show maps & draw routes on maps. My application supports for ios 4 plus. So how should i use maps to work on ios 6 as well as before. Also i want to know sholud i use custom mapview in my app to display maps & routes or should i use
[[UIApplication sharedApplication] openURL:]
I have never user MapKits
. So please provide if any tutorial. Also let me know if there are any rd party libraries that can be used.
If you don't want an in-app map. Use the following:
NSString *destinationAddress = @"Amsterdam";
Class itemClass = [MKMapItem class];
if (itemClass && [itemClass respondsToSelector:@selector(openMapsWithItems:launchOptions:)]) {
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder geocodeAddressString:destinationAddress completionHandler:^(NSArray *placemarks, NSError *error) {
if([placemarks count] > 0) {
MKPlacemark *placeMark = [[MKPlacemark alloc] initWithPlacemark:[placemarks objectAtIndex:0]];
MKMapItem *mapItem = [[MKMapItem alloc]initWithPlacemark:placeMark];
MKMapItem *mapItem2 = [MKMapItem mapItemForCurrentLocation];
NSArray *mapItems = @[mapItem, mapItem2];
NSDictionary *options = @{
MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving,
MKLaunchOptionsMapTypeKey:
[NSNumber numberWithInteger:MKMapTypeStandard],
MKLaunchOptionsShowsTrafficKey:@YES
};
[MKMapItem openMapsWithItems:mapItems launchOptions:options];
} else {
//error nothing found
}
}];
return;
} else {
NSString *sourceAddress = [LocalizedCurrentLocation currentLocationStringForCurrentLanguage];
NSString *urlToOpen = [NSString stringWithFormat:@"http://maps.google.com/maps?saddr=%@&daddr=%@",
[sourceAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding],
[destinationAddress stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlToOpen]];
}
This opens the map application and checks if it is ios5 or ios6.
For ios5 I use the LocalizedCurrentLocation
from this post http://www.martip.net/blog/localized-current-location-string-for-iphone-apps
For ios6 I use the CLGeocoder to get the placemark and then open the map with it and the current location.
Remember to add CoreLocation.framework
and MapKit.framework
