iOS啥都不用干,只要这样:
- (BOOL)application:(__unused UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
RCTEnableTurboModule(YES); //*
_bridge = [[RCTBridge alloc] initWithDelegate:self launchOptions:launchOptions];
// ...略...
}
然后再实现一个RCTTurboModule
的protocol
。可以参考iOS的CoreModules里面的实现。
参考官方repo。
