查看 Bundle Identifier

IOS 局部

主动部署 CocoaPods

装置工具

sudo gem install cocoapods

ios/flutter_baidu_plugin_ducafecat.podspec

  ...  s.dependency 'Flutter'  s.platform = :ios, '8.0'  s.dependency 'BMKLocationKit'  # Flutter.framework does not contain a i386 slice. Only x86_64 simulators are supported.  s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'VALID_ARCHS[sdk=iphonesimulator*]' => 'x86_64' }end

装置百度 sdk 包

pod install

降级

pod repo update

pod search 无奈搜寻到类库的解决办法（找不到类库）

（1）执行pod setup（2）删除~/Library/Caches/CocoaPods目录下的search_index.json文件    pod setup胜利后会生成~/Library/Caches/CocoaPods/search_index.json文件    终端输出rm ~/Library/Caches/CocoaPods/search_index.json    删除胜利后再执行pod search（3）执行pod search

Info.plist 定位受权

<dict>    <key>NSLocationWhenInUseUsageDescription</key>    <string>须要定位</string>

Flutter 局部

设置 AK

  @override  void initState() {    super.initState();    _requestPermission(); // 执行权限申请    if (Platform.isIOS == true) {      FlutterBaiduPluginDucafecat.setApiKeyForIOS(          "dkYT07blcAj3drBbcN1eGFYqt16HP1pR");    }  }

其它代码和 android 同接口无影响
