MkMapView Zoom Level
- by meetS
I m using MkMapView with google maps.I succeed to show map view and address with annotation pin.But I want increased zoom level.How Can I Set it programmatically??
(void) showMyAddress {
//Hide the keypad
MKCoordinateRegion region;
MKCoordinateSpan span;
span.latitudeDelta=0.2;
span.longitudeDelta=0.2;
CLLocationCoordinate2D location = [self addressLocation];
region.span=span;
region.center=location;
if(addAnnotation != nil) {
[mapView removeAnnotation:addAnnotation];
[addAnnotation release];
addAnnotation = nil;
}
addAnnotation = [[AddAnnotation alloc] initWithCoordinate:location ];
[addAnnotation setMTitle:@"abc"];
[addAnnotation setMSubTitle:@"def."]
[mapView addAnnotation:addAnnotation];
[mapView setRegion:region animated:TRUE];
[mapView regionThatFits:region];
}
-(CLLocationCoordinate2D) addressLocation {
NSString *urlString = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv",
[@"abc" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *locationString = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlString] encoding:NSStringEncodingConversionAllowLossy error:nil];
NSArray *listItems = [locationString componentsSeparatedByString:@","];
double latitude = 0.0;
double longitude = 0.0;
if([listItems count] >= 4 && [[listItems objectAtIndex:0] isEqualToString:@"200"]) {
latitude = [[listItems objectAtIndex:2] doubleValue];
longitude = [[listItems objectAtIndex:3] doubleValue];
}
else {
}
CLLocationCoordinate2D location;
location.latitude = latitude;
location.longitude = longitude;
return location;
}
