Weex 初始化 Weex

建议在 ​didFinishLaunchingWithOptions​ 回调中初始化 Weex，你也可以在子线程中异步初始化，但需要确保渲染 Weex 页面前初始化已经全部完成。

// App configuration
[WXAppConfiguration setAppGroup:@"Your app group"];
[WXAppConfiguration setAppName:@"Your app name"];
[WXAppConfiguration setAppVersion:@"Your app version"];

//Initialize WeexSDK
[WXSDKEngine initSDKEnvironment];

//Register custom modules and components, optional.
[WXSDKEngine registerComponent:@"myview" withClass:[MyViewComponent class]];
[WXSDKEngine registerModule:@"mymodule" withClass:[MyWeexModule class]];

//Register the implementation of protocol, optional.
[WXSDKEngine registerHandler:[WXAppNavigationImpl new] withProtocol:@protocol(WXNavigationProtocol)];

//Set the log level, optional
[WXLog setLogLevel: WXLogLevelWarning];
