我正在尝试按照此处的指南在 iOS 中加载谷歌地图视图

我为地图视图创建了一个名为 iptechMapViewController.h 、 iptechMapViewController.m 和 iptechMapViewController.xib 的新 viewController

这是 iptechMapViewController.m 中的代码：

#import "iptechMapViewController.h"

#import <GoogleMaps/GoogleMaps.h>

@interface iptechMapViewController ()
{
    GMSMapView *mapView_;
}

@end

@implementation iptechMapViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
    // Custom initialization
    }
return self;
}

- (void)loadView
{
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
                                                        longitude:151.2086
                                                             zoom:6];
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.myLocationEnabled = YES;
    self.view = mapView_;

    GMSMarker *marker = [[GMSMarker alloc] init];
    marker.position = CLLocationCoordinate2DMake(-33.8683, 151.2086);
    marker.title = @"Sydney";
    marker.snippet = @"Australia";
    marker.map = mapView_;
 }

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

 }

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
 }

@end

然后在另一个名为 iptechFlipsideViewController.m 的视图控制器中，我试图显示 iptechMapViewController 如下：

- (IBAction)showMap:(id)sender
{
 iptechMapViewController *controller = [[iptechMapViewController alloc] initWithNibName:@"iptechMapViewController" bundle:nil];    
[self.view addSubview:controller.view];
}

但是在单击连接到 IBAction showMap 的 showMap 按钮后，在 iOS 请求访问我的位置警报的权限后，我点击确定，之后什么都没有显示，并且在控制台中我收到以下错误“

Failed to make complete framebuffer object 8cd6

谢谢

仅当地图视图是根视图控制器的根视图时传递CGRectZerotomapWithFrame才有效 - 在这种情况下，它会调整大小以适应屏幕。在您的情况下，由于地图是子视图，因此您需要在创建地图视图时指定大小。
