无法将google地图GMSMapView放在主要主视图的子视图中？ [英] Cannot put a google maps GMSMapView in a subview of main main view?

问题描述

我正在努力解决这个问题！
我想将一个谷歌地图 GMSMapView 添加到 UIView 中，这只是主要部分 UIView 我的 ViewController 。

I'm struggling with this problem! I want to add a google maps GMSMapView into a UIView that is only a portion of the main UIView of my ViewController.

应该很简单。 ..我在故事板上创建了一个 UIView 我想要的大小并把它放在主 UIView 中。

It should be simple... I created with the storyboard a UIView of the size I want and put it in the main UIView.

接口文件的片段：

@interface MapViewController : UIViewController <CLLocationManagerDelegate>

@property(nonatomic) IBOutlet GMSMapView *mapView;

将mapView链接到此 UIView 里面主 UIView 。

With the mapView linked with this UIView inside the main UIView.

我在实施中做了什么：

@synthesize mapView = _mapView;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
                                                            longitude:151.2086
                                                                 zoom:10];
    _mapView = [GMSMapView mapWithFrame:_mapView.bounds camera:camera];
    _mapView.myLocationEnabled = YES;

}

这应该有效，不应该吗？
我得到的是我的内部UIView是空的。

This should work, shouldn't it? What I get is that my internal UIView is empty.

如果我按照google的开始指南实例化地图谷歌地图集成文档，它可以工作，但它将地图分配给MAIN UIView，这是另一回事。

If I instantiate a map following google's starting guide Google Map Integration Document, it works but it assigns the map to the MAIN UIView and thats a different thing.

我甚至尝试将故事板中mapView的类从 UIView 更改为 GMSMapView 。
地图显示在内部视图中，但它以奇怪的方式初始化

I tried even changing the class of my mapView in the storyboard from UIView to GMSMapView. The map is showed in the inner view but it is initialized in a strange way making

1. 系统抛出错误说

无法制作完整的帧缓冲区

"Failed to make complete frame buffer"

并减慢了视频的加载速度（在模拟器上需要2-3秒）

and slowing down a lot the loading of the view (it takes 2-3 seconds on the simulator)

1. 地图在 viewDidLoad 方法中完成的任何相机更改都没有响应。

1. The map not responding in any camera change done in the viewDidLoad method.

有任何建议吗？

我在StackOverflow上阅读了一些帖子，但找不到有效的解决方案：（

I read some posts here on StackOverflow but couldn't find a valid solution :(

推荐答案

根据其他答案，这里有三种实际工作方式。

Based on other answers, here are three ways that actually work.

1. 在XIB上放置一个视图，并在XIB构建器中将其类更改为GMSMapView。请参阅下面的* map1。或者......


2. 将其全部编码。将地图添加为子视图主视图。请参阅下面的* map2。或者......


3. 添加地图a是XIB中已有出口的另一个子视图的子视图。 * map3如下。

.h

@interface GPViewController : UIViewController
@property (strong, nonatomic) IBOutlet GMSMapView *map1;
@property (strong, nonatomic) IBOutlet UIView *plainViewOnXIBHoldsMap3;
@end

.m

- (void)viewDidLoad{
    [super viewDidLoad];
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.0
                                                        longitude:151.20
                                                             zoom:6];

    /* Option 1. view on XIB is class GSMMapView */
    self.map1.camera = camera;

    /* Option 2. add a map as a subview */
    GMSMapView *map2 = [GMSMapView mapWithFrame:CGRectMake(0, 0, 100, 100) camera:camera];
    [self.view addSubview:map2];

    /* Option 3. add a map to a subview already on the XIB */
    GMSMapView *map3 = [GMSMapView mapWithFrame:self.plainViewOnXIBHoldsMap3.bounds camera:camera];
    [self.plainViewOnXIBHoldsMap addSubview:map3];
}
