react-native之react-native-vector-icons

在RN中使用react-native-vector-icons图标库引用方式，在项目根目录打开命令行执行以下命令

npm install react-native-vector-icons –save
react-native link react-native-vector-icons

打开xcode点击想目—》info.plist 就能查到已经被引用，如下图：（以iOS为例）

随后再清一下缓存 执行以下命令：

react-native link react-native-vector-icons
react-native start –reset-cache
react-native run-ios

执行完以上命令就可以在项目中使用了，举个列子：

import Ionicons from 'react-native-vector-icons/Ionicons';   //首先引用

return ;  // 使用

附上完整demo(TabNavigation)代码：

            }

            // 在此处可以返回任何组件！
            // 我们通常使用react-native-vector-icons中的图标组件
            return ;
          },
		})
	}
);
