iphone - 使用 GoogleMaps APIv3 在 iOS 环境中开发用户界面

Question

我是 iOS 开发的新手。今天，我创建了一个新的“SingleViewApplication”。我使用故事板添加了新的导航栏。

接下来，我按照教程https://developers.google.com/maps/documentation/ios/start将 Google 地图集成到我的项目中。

但是，添加 GoogleMaps 后，我的导航栏消失了。不知何故，谷歌地图覆盖了使用故事板构建的界面。

任何建议，教程，信息都非常感谢。

代码如下：

shareAppDelegate.h

#import <UIKit/UIKit.h>
@interface shareAppDelegate : UIResponder <UIApplicationDelegate>
@property (strong, nonatomic) UIWindow *window;
@end

@implementation shareAppDelegate

{
    [GMSServices provideAPIKey:@"AIzaSyDqbi8tp0DeUHQKASyRyJUqJbOZpMOuuig"];
    // Override point for customization after application launch.
    return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application
{
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

- (void)applicationWillEnterForeground:(UIApplication *)application
{
    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}
