我按照Google Maps SDK for iOS - Getting started链接中提到的步骤进行操作。以下是我创建的文件

AppDelegate.m

#import "AppDelegate.h"
#import "ViewController.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.viewController = [[ViewController alloc] initWithNibName:@"ViewController" bundle:nil];
    [GMSServices provideAPIKey:@"AIzaXXXXXXXXXXeGuCyxChdTECXXXXXXXXXXV9E"];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];

    return YES;
}
//Other functions are there as it is.

视图控制器.m

#import "ViewController.h"
#import <GoogleMaps/GoogleMaps.h>

@interface ViewController ()

@end

@implementation ViewController 
{
    GMSMapView *mapView_;
}

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

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

- (void)loadView 
{
    // Create a GMSCameraPosition that tells the map to display the
    // coordinate -33.86,151.20 at zoom level 6.
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                        longitude:151.20
                                                             zoom:6];
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.myLocationEnabled = YES;
    self.view = mapView_;

    // 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_;
}

@end

主文件

#import <UIKit/UIKit.h>

#import "AppDelegate.h"

int main(int argc, char *argv[])
{
    @autoreleasepool 
    {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
        //Error is displayed in the above line.
    }
}

以下是错误的详细信息

你的错误是：

'+[GMSCameraPosition cameraWithLatitude:longitude:zoom:]: 无法识别的选择器发送到类 0x25ad5c'

根据似乎已定义的 SDK。那是怎么定义的？如果它是一个类别，您可能需要使用标志 -ObjC 和 -all_load 链接 SDK。
