React-native包返回undefined

Question

我按照说明安装了react-native-google-places但是当我尝试运行该应用时出现此错误：

以下是我采取的步骤：

1）react-native init awesomeApp && cd awesomeApp

2）yarn add react-native-google-places

3）react-native link react-native-google-places

4）在/ ios文件夹中，我创建了包含此内容的podfile

source 'https://github.com/CocoaPods/Specs.git'
target 'awesomeApp' do
  pod 'GooglePlaces'
  pod 'GoogleMaps'
  pod 'GooglePlacePicker'
end

5）我使用谷歌创建了一个API密钥（我现在暂时共享这个密钥，但稍后将禁用它：AIzaSyA5u8ez8uuyGvAa98XzH7rY1MCnHrED-rw）

6）我将AppDelegate.m文件更新为：

@import GooglePlaces;
@import GoogleMaps;

#import "AppDelegate.h"

#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  NSURL *jsCodeLocation;

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

  [GMSPlacesClient provideAPIKey:@"AIzaSyDEmY7AqrJbrr1oD4Pe82H_xAHt3C0xafM"];
  [GMSServices provideAPIKey:@"AIzaSyDEmY7AqrJbrr1oD4Pe82H_xAHt3C0xafM"];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
                                                      moduleName:@"awesomeApp"
                                               initialProperties:nil
                                                   launchOptions:launchOptions];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  return YES;
}
@end

7）我从/ ios

运行pod install

8）然后react-native run-ios从根

9）我在index.ios.js中加入import RNGooglePlaces from 'react-native-google-places';

10）然后在RNGooglePlaces.openAutocompleteModal();

之前的渲染函数中添加return

据我所知，这些步骤应该会产生一个带有Google地方自动填充功能的模式。有人可以指出它为什么没有？
