Question

I want to add SegmentedControl to my MKMapView With three Segments

1. StandardView
2. SatelliteView

and we can change map type by taping segments

i have try some code

- (void)indexDidChangeForSegmentedControl:(UISegmentedControl *)aSegmentedControl {

NSArray *itemArray = [NSArray arrayWithObjects: @"One", @"Two", @"Three", nil];
segControl= [[UISegmentedControl alloc] initWithItems:itemArray];

if((segControl.selectedSegmentIndex = 0)){
    _mapView = MKMapTypeStandard;
}
if((segControl.selectedSegmentIndex = 1)){
    _mapView = MKMapTypeSatellite;
}
else {
    _mapView = MKMapTypeHybrid;
}

}

Hey try with this condition segControl.selectedSegmentIndex == 0 instead of this segControl.selectedSegmentIndex = 0

here problem with single = sign

and Also try like this bellow code..

- (void)viewDidLoad
{
      segControl = [[UISegmentedControl alloc]initWithItems:[NSArray arrayWithObjects: @"One", @"Two", @"Three", nil]];
      [segControl addTarget:self action:@selector(indexDidChangeForSegmentedControl:) forControlEvents:UIControlEventValueChanged];
      [segControl setFrame:CGRectMake(50,20,200,44)];//set frame which you want
      [self.view addSubview:segControl];
}

- (void)indexDidChangeForSegmentedControl:(UISegmentedControl *)aSegmentedControl {
    switch (aSegmentedControl.selectedSegmentIndex) {
            case 0:
                map.mapType = MKMapTypeStandard;
                break;
            case 1:
                map.mapType = MKMapTypeSatellite;
                break;
            case 2:
                map.mapType = MKMapTypeHybrid;
                break;

            default:
                break;
        }
}
