适用于Flutter iOS设置的Google Maps

Question

设置官方Google Maps for Flutter插件的说明包括将Google API密钥添加到AppDelegate.m文件中:

在应用程序委托ios/Runner/AppDelegate.m中指定您的API密钥:

#include "AppDelegate.h" 
#include "GeneratedPluginRegistrant.h"
#import "GoogleMaps/GoogleMaps.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GMSServices provideAPIKey:@"YOUR KEY HERE"];
  [GeneratedPluginRegistrant registerWithRegistry:self];
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end

我的flutter项目有一个AppDelegate.swift文件而不是AppDelegate.m文件,我不知道如何添加所需的密钥,因为语法不同:

import UIKit
import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

谁能帮我吗？

Answer 1

您可以按如下方式添加API密钥:

AppDelegate.swift:

import UIKit
import Flutter
import GoogleMaps // Add this line!

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
  ) -> Bool {
    GeneratedPluginRegistrant.register(with: self)
    GMSServices.provideAPIKey("YOUR_API_KEY")  // Add this line!
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

还有一件事，不要忘记在ios/Runner/Info.plist上添加以下行

<key>io.flutter.embedded_views_preview</key>
<true/>
