GMSMapView隐藏导航栏

Question

I implemented the GMSMapView via the Googla Maps iOS SDK

the example code from Google suggests to declare the view more or less just dropping this method in your code

- (void)loadView {
    // Create a GMSCameraPosition that tells the map to display the
    // coordinate -33.86,151.20 at zoom level 6.
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                            longitude:151.20
                                                                 zoom:6];
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.myLocationEnabled = YES;
    self.view = mapView_;

    // Creates a marker in the center of the map.
    GMSMarker *marker = [[GMSMarker alloc] init];
    marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
    marker.title = @"Sydney";
    marker.snippet = @"Australia";
    marker.map = mapView_;
}

it automagically works, but the mapView happens to cover my navigationItem it's clear that the maps take its dimension at the initWithFram:CGRectZero but simply changing the parameter to a custom CGRect

CGRect square = CGRectMake(100, 100, 100, 100);

haven't worked for me, any other suggestion? i only need to display the map between the Nav Item and the Tab Bar (but the second doesn't happen to be covered)

Answer 1

Make sure your view controller for the map is part of a navigation stack of a UINavigationController . I had no problems pushing a UITabBarController with a map and a list tab onto a view controller embedded in a UINavigationController . This way the navigationbar view belongs only to the UINavigationController and the map controller view shouldn't cover it.

The problem was that the mapView_ was being set as the whole view

self.view = mapView_;

calculating the correct dimension and adding it as a subview was the correct way to solve it

CGRect f = self.view.frame;
CGRect mapFrame = CGRectMake(f.origin.x, 44, f.size.width, f.size.height);
mapView_ = [GMSMapView mapWithFrame:mapFrame camera:camera];
[self.view addSubview:mapView_];
