调整谷歌地图的大小

Question

我尝试使用来自GoogleMapsSDKDemos的代码将mapview调整为屏幕上更小的矩形，但它似乎没有任何效果。下面是我的代码:

mapView = [[GMSMapView alloc] initWithFrame:CGRectZero];mapView。camera = [gmscamerposition] cameraWithLatitude:38.98549782690282经度:-76.94636067188021变焦:17],

self.view = [[UIView alloc] initWithFrame:CGRectZero];
mapView.autoresizingMask =
UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
mapView.frame = self.view.frame;
mapView.clipsToBounds = YES;
mapView.myLocationEnabled = YES;
mapView.settings.tiltGestures = NO;
mapView.settings.zoomGestures = NO;
mapView.frame = CGRectMake(0,0, 10, 25);
[self.view addSubview:self.mapView];

倒数第二行似乎应该将MapView限制为一个小正方形，但它仍然占据整个屏幕。

Answer 1

我会尝试这样做:

GMSCameraPosition* camera = [GMSCameraPosition 
    cameraWithLatitude: 38.98549782690282 
    longitude: -76.94636067188021 
    zoom: 17];
GMSMapView* mapView = 
    [GMSMapView mapWithFrame: GRectMake(0,0, 10, 25) camera: camera];

注意，GMSMapView.h中GMSMapView类的注释说:

这个类不应该直接被初始化，而必须被初始化创建与[GMSMapServices mapWithFrame:camera:]

Answer 2

尝试将地图添加到视图顶部:

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:latitude
                                                        longitude:longitude
                                                             zoom:10];

mapView_ = [GMSMapView mapWithFrame:CGRectMake(0,0, width, height) camera:camera];
mapView_.delegate = self;
mapView_.myLocationEnabled = YES;
[self.view addSubview:mapView_];
