ios - 旋转到横向时，Google Maps SDK for iOS 问题

Question

我有一个来自适用于 iOS 的 Google Maps SDK(最新版本)的 Google Map。我在 UIScrollerView 中显示这样的 map :

showMarker = YES;
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:[geocodeLatitude floatValue] longitude:[geocodeLongitude floatValue] zoom:13];
[self setupMapWithCamera:camera withLatitude:geocodeLatitude withLongitude:geocodeLongitude];

float mapHeight = 50;
[mapView_ setFrame:CGRectMake(0, 0, widthOfBlock, mapHeight)];
[self.scroller addSubview:mapView_];

调用的方法是:

-(void)setupMapWithCamera:(GMSCameraPosition *)camera withLatitude:(NSString *)Slatitude withLongitude:(NSString *)Slongitude {
    // setup map
    [mapView_ clear];
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.settings.scrollGestures = NO;
    mapView_.settings.zoomGestures = NO;

    // setup marker
    if (geocodesuccess || showMarker) {
        GMSMarker *marker = [[GMSMarker alloc] init];
        marker.position = CLLocationCoordinate2DMake([Slatitude floatValue], [Slongitude floatValue]);
        if ([ShopWithDatas.open isEqualToString:@"1"] || [ShopWithDatas.open2424 isEqualToString:@"1"]) {
            marker.icon = [GMSMarker markerImageWithColor:[UIColor greenColor]];
        } else {
            marker.icon = [GMSMarker markerImageWithColor:[UIColor redColor]];
        }
        [mapView_ setSelectedMarker:marker];
        marker.map = mapView_;
    }    
}

因此，当您从 Portrait => Portrait 进入此 View 时，它会起作用。当您从 Landscape => Landscape 进入此 View 时，它会起作用。

但是当您从肖像 => 肖像然后在 View 中更改为风景时，相机不再居中。另外，当您从 Landscape => Landscape 进入此 View 然后变成 Portrait 时，它会起作用。

知道如何解决肖像 => 风景问题的相机吗？

最后，即使我不明白为什么它不能正确更新，我还是找到了这个解决方案:

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
    if (canIshowMap) {
        CLLocationCoordinate2D actualLocation = CLLocationCoordinate2DMake([geocodeLatitude floatValue], [geocodeLongitude floatValue]);
        GMSCameraUpdate *updatedCamera = [GMSCameraUpdate setTarget:actualLocation];
        [mapView_ moveCamera:updatedCamera];
        //[mapView_ animateToLocation:actualLocation];        
    }
}

请注意，注释行并不能修复错误。
