RN-ios打包步骤

第一步 :

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;
  NSURL *jsCodeLocation;
#ifdef DEBUG

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index" fallbackResource:nil];
//  jsCodeLocation = [NSURL URLWithString:@"http://127.0.0.1:8081/index.ios.bundle?platform=ios&dev=true"];

#else
  jsCodeLocation = [[NSBundle mainBundle] URLForResource:@"index.ios" withExtension:@"jsbundle"];
#endif

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
        moduleName:@"qqgl2    initialProperties:nil  launchOptions:launchOptions];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];
  self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
  UIViewController *rootViewController = [UIViewController new];
  rootViewController.view = rootView;
  self.window.rootViewController = rootViewController;
  [self.window makeKeyAndVisible];
  // 启动图片延时: 1秒
  [NSThread sleepForTimeInterval:2];
  return YES;
}

第二步:

打开终端，进入你的rn工程,在根目录下执行bundle命令,指定到rn项目的ios工程文件夹下，记得一定要先创建bundle文件夹，不然终端会报文件夹找不到的错误, assets文件夹的路径不需要手动创建

$   react-native bundle --entry-file ./index.js --bundle-output ./ios/bundle/index.ios.jsbundle --platform ios --assets-dest ./ios/bundle --dev false
