將Google地圖分配給子視圖時的黑屏

Question

我正在嘗試在Google Map View中爲iOS6加載地點。 如何設置地圖的框架？ 目前，它是全屏

-(void)loadView { 

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:10.00989 
                 longitude:76.316142 
                  zoom:15]; 
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera]; 
    self.view = mapView_; 

    } 

我試圖用當前視圖中創建一個新的（小）查看並添加地圖內部的，但當時的頁面沒有得到loaded.It顯示全屏黑屏

-(void)loadView { 

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:10.00989 
                 longitude:76.316142 
                  zoom:15]; 
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera]; 

    [self.view Addsubview:newView]; 
    self.newView = mapView_; 

    } 

Answer 1

嘗試

mapView_ = [GMSMapView mapWithFrame:self.view.bounds camera:camera]; 

[self.view addSubview:mapView_]; 

Answer 2

，如果你投入的loadView它不會有一個觀點..廈門國際銀行的甚至沒有加載中... 把它放在viewDidLoad中

，做

mapView_ = [GMSMapView mapWithFrame:self.view.bounds camera:camera]; 
[self.view addSubview:mapView_];

終於找到了解決辦法。 取出的loadView方法，並把下面的代碼在視圖中沒有加載方法：

-(void)viewDidLoad{ 
    [super viewDidLoad]; 

    // Do any additional setup after loading the view from its nib. 
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86 
                  longitude:151.20 
                   zoom:6]; 

    mapView_ = [GMSMapView mapWithFrame:CGRectMake(0, 0, 100, 100) camera:camera]; 
    [self.view addSubview:mapView_]; 
    // Create a GMSCameraPosition that tells the map to display the 
    // coordinate -33.86,151.20 at zoom level 6. 

    mapView_.myLocationEnabled = YES; 

    // 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_; 
}

檢查申報@property爲GMSMapView中，如果是弱屬性然後使它強。

@property（strong，nonatomic）GMSMapView * mapView;
