Question

我已经在我的react-native项目的android部分中成功实现了接收共享意图处理。现在，我想对iOS部分做同样的事情。

可以更好地了解我在android中所做的事情，以及我想要在iOS中所做的事情。为了清楚起见，我将显示一些代码片段。我不确定iOS世界中的所有术语都叫什么，这使得搜索知识/示例非常困难。希望SO上的某个人了解这两个平台，并且可以将android转换为iOS术语？

要使我的应用显示在本机android的“共享方式”菜单中，我将这些意图过滤器添加到了我的 AndroidManifest.xml

  <intent-filter>
      <action android:name="android.intent.action.MAIN" />
      <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
  <intent-filter>
    <action android:name="android.intent.action.SEND" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="text/plain" />
  </intent-filter>

这允许用户标记一些文本（我的案例网址），并将该网址直接共享给我的应用。要将共享的URL传递给我在 MainActivity.kt 之后添加的react-native部分（也可能是Java）

class MainActivity : ReactActivity() {
    override fun createReactActivityDelegate(): ReactActivityDelegate {
        return object : ReactActivityDelegate(this, mainComponentName) {
            override fun getLaunchOptions(): Bundle? {
                return gerenateBundleFromIntent(intent)
            }
        }
    }


    private fun gerenateBundleFromIntent(intent: Intent) : Bundle {
        val bundle = Bundle()
        when {
            intent?.action == Intent.ACTION_SEND -> {
                if ("text/plain" == intent.type) {
                    intent.getStringExtra(Intent.EXTRA_TEXT)?.let {
                        bundle.putString("shareUrl", it)
                    }
                }
            } else -> {
            // Handle other intents, such as being started from the home screen
            }
        }
        return bundle
    }
}

putString("shareUrl", it)将成为名为shareUrl

的本机道具。

这使我可以像这样在本机代码（ app.js ）中接收数据：

export default class App extends Component<Props> {
  constructor(props) {
    super(props)
    this.state = {
      uri: undefined,
      shareUrl: this.props.shareUrl
    }
  }
...
}

如果可能的话，我希望以类似的方式在iOS设备上共享此应用程序的URL，并将该URL传递给我的nakve App.js的shareUrl道具

从哪里开始？这些是react-native cli生成的iOS目录，我需要添加哪些文件？

You can use UIActivityViewController to share something from your iOS app to other apps,

func shareSomething() {
  let text = "abc"
  let image = UIImage(named: "ABC")
  let url = NSURL(string:"https://www.google.com")
  let share = [text , image! , url]
  let activityViewController = UIActivityViewController(activityItems: shareAll, applicationActivities: nil)
  activityViewController.popoverPresentationController?.sourceView = self.view 
  self.present(activityViewController, animated: true, completion: nil)
}

objective-c code is,

- (void)shareSomething
{
    NSURL *url = [NSURL fileURLWithPath:imagePath];
    NSArray *objectsToShare = @[url];
    UIActivityViewController *controller = [[UIActivityViewController alloc] initWithActivityItems:objectsToShare applicationActivities:nil];
    [controller setCompletionHandler:^(NSString *activityType, BOOL completed)
    {

    }]
    [self presentViewController:controller animated:YES completion:nil];
}

and if you want to pass something from the iOS to react-native as props, you can do that in AppDelegate.m file, inside

didFinishLaunchingWithOptions

function. Like this,

NSArray *imageList = @[@"http://foo.com/bar1.png",
                   @"http://foo.com/bar2.png"];

NSDictionary *props = @{@"images" : imageList};

RCTRootView *rootView = [[RCTRootView alloc] initWithBridge:bridge
                                             moduleName:@"YOUR_APP_NAME"
                                      initialProperties:props];
