Hi I have integrated MKMapView map in my iOS application. Apple maps show different view for one place and MKMapview shows different view for same place. How can I get clear view with zoom level like Apple maps.
This is the Apple maps view screenshot link
This is the MKMapView map screenshot link
it's look like the same place. But issue it you map has less zoom level.
Reduce you span value to make it more zoom. So you will get the same result. Try to solve by error and trial. you can check the below code to set span value of the map.
MKCoordinateSpan span;
span.latitudeDelta = 0.4;
span.longitudeDelta = 0.4;
MKCoordinateRegion region;
region.center = newLocation.coordinate;
region.span = span;
[mapView setRegion:region animated:NO];

Google Maps has had this for a while (double tap then hold and slide finger up or down to zoom in or out) but Apple is just adding it to their Apple Maps app in iOS 11.
It does not seem like they are going to add this to MKMapView, at least not in the current betas.
If Apple does not give MKMapView this functionality how would I do this using gestures? Has anyone else done this?
This will help you to zoom out to world-view.
// step.1 create co-ordianate-span as follows
MKCoordinateSpan span = {.latitudeDelta = 180, .longitudeDelta = 360};
// step.2 crate region as follows
MKCoordinateRegion region = MKCoordinateRegionMake(CLLocationCoordinate2DMake(0.0000f, 0.0000f), span);
// step.3 zoom using region to map as follows
[self.mapView setRegion:region animated:YES];
Please check the below Image. How to Avoid this type of zoom level in iPhone
Now getting Result:
Expected Result:
I don't think there is a way of telling if satellite images would be available at zoom level for given region. Better approach is to set your MKMapView to MKMapTypeStandard and give the user the option of switching to MKMapTypeSatellite in this case you will always have a map details to display on initial presentation of your MKMapView object
You can set the zoom by using MKCoordinateRegion and setting its span latitude & longitude delta as:
MKCoordinateRegion region;
region.center.latitude = {desired lat};
region.center.longitude = {desired lng};
region.span.latitudeDelta = 1;
region.span.longitudeDelta = 1;
region = [mapView regionThatFits:region];
[mapView setRegion:region animated:TRUE];
Vary the span.longitudeDelta and span.latitudeDelta to get the required zoom.
I am using following codes
MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(CLLocationCoordinate2DMake(annView.annotation.coordinate.latitude, annView.annotation.coordinate.longitude - .04), Some KM, Some KM);
MKCoordinateRegion adjustedRegion = [self.mapView regionThatFits:viewRegion];
[self.mapView setRegion:adjustedRegion animated:YES];
Otherway around is
MKCoordinateRegionMake(CLLocationCoordinate2DMake(annView.annotation.coordinate.latitude, annView.annotation.coordinate.longitude - .04), ADD SPAN HERE)
Both of these makes the map zoom. How is it possible that I change the Region without any zoom.
Get the current region and just change the center point.
// get current region
MKCoordinateRegion region = self.mapView.region;
// Update the center
region.center = CLLocationCoordinate2DMake(annView.annotation.coordinate.latitude, annView.annotation.coordinate.longitude - .04);
// apply the new region
self.mapView.region = region;
If you have a coordinate to set, use the MKMapView -setCenterCoordinate:animated: method. Animating the position change gives the user a clue about what's happened.
CLLocationCoordinate2D coordinate = annView.annotation.coordinate;
[myMapView setCenterCoordinate:coordinate animated:YES];
Also, no need to make a new coordinate, just use the one already in the annotation view.
I wanna zoom into the user current location when the app starts in the MapKit.
This is my code (in the viewDidLoad function):
Locate=[[CLLocationManager alloc]init];
Locate.delegate=self;
Locate.desiredAccuracy=kCLLocationAccuracyBestForNavigation;
Locate.distanceFilter=kCLDistanceFilterNone;
[Locate startUpdatingLocation];
[super viewDidLoad];
//Region
MKCoordinateRegion myRegion;
//Center
CLLocationCoordinate2D center;
center.latitude=Locate.location.coordinate.latitude;
center.longitude=Locate.location.coordinate.longitude;
//Span
MKCoordinateSpan span;
span.latitudeDelta=0.3f;
span.longitudeDelta=0.3f;
//Set Region
myRegion.center=center;
myRegion.span=span;
[_MyMap setRegion:myRegion animated:YES];
Also I implemented the didUpdateLocation function with the same code as previous.
The problem is that when the user location is changing (when the user is moving) the screen makes zoom at him but I can't move the screen, if I try to move it return to the user location immediately, so I can't see the whole map.
For Zooming the map you have to change the region values means center and span.once see this one Mapview Zoom
in my case i have used this one for moving the map when i click on particular button.
MKCoordinateSpan span = MKCoordinateSpanMake(30.5982f,0.0001f);
CLLocationCoordinate2D coordinate = {36, 90};
MKCoordinateRegion region = {coordinate, span};
MKCoordinateRegion regionThatFits = [self.mapView regionThatFits:region];
[self.mapView setRegion:regionThatFits animated:YES];
I solved this issue by adding touchesMoved function and I stopped updating the Location in this function.
Solved.
Hi have MKMapView and I make it to zoom depending on the annotations added to mapview, but sometimes I see map zoomed to some level in which annotations fall on the edges and half visible. Below is the code i'm using to set the map region.
MKPolygon *poly = [MKPolygon polygonWithCoordinates:points count:annotationCount];
MKCoordinateRegion region=MKCoordinateRegionForMapRect([poly boundingMapRect]);
Please provide some solution, Thanks.
So your region is too small, have you considered making it bigger?
Your MKCoordinateRegion has a CLLocationCoordinate2D (center) and a MKCoordinateSpan (span). That MKCoordinateSpan has a latitudeDelta (consider this the height) and a longitudeDelta (consider this the width). What you want to do is a make a slightly larger region. So my first guess is
region.span.latitudeDelta = region.span.latitudeDelta * 1.01;
Then set your mapview to that region
