这段代码报错：Missing context of method declaration

#import "RCTWeChat.h"

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
  return [[RCTWeChat shareInstance] handleOpenURL: url];
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
  return [[RCTWeChat shareInstance] handleOpenURL: url];
}

我记得一个是iOS8和iOS9的区别，你只需要实现一个，所以要判断设备的系统！
