注意该项目必须在设备上运行,iOS或安卓
背景:
我已经使用命令 $ ionic plugin add cordova-plugin-googlemaps --variable API_KEY_FOR_ANDROID="YOUR_ANDROID_API_KEY_IS_HERE" --variable API_KEY_FOR_IOS="YOUR_IOS_API_KEY_IS_HERE"
将我的原生Google地图插件安装到了我的ionic 2项目中,如以下链接所示:http://ionicframework.com/docs/v2/native/google-maps/
然后我会运行命令$ ionic platform add ios
然后$ ionic build ios
一切如预期,直到这一点。 当我尝试显示地图时,我看到一个黑色的屏幕,不知道什么是失踪!
