如何从iOS中的React Native Component返回到Native viewController

Starting Screen React Native Screen with Data

我想从Native viewController中的本机组件回复iOS。

在我目前的项目中，我使用Native code（Obj C）实现了一些屏幕，并使用{{1实现了一些具有图形和一些复杂仪表板UI的屏幕（使用React Native） }}。

我正在从JavaScript推送ReactNativeObjCViewController，并通过继承ViewConrtoller从ReactNativeObjCViewController加载React Native View（带导航的标签栏）。

成功加载React Native视图并根据实现显示正确的数据。现在我想回到本地视图，即来自React Native Component的RCTRootView。

请帮助我。

// ViewConrtoller.m

// ReactNativeObjCViewController.h 

#import "ViewController.h"

#import "ReactNativeObjCViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

-(IBAction)moveToNext:(id)sender
{
  ReactNativeObjCViewController *rootViewController = (ReactNativeObjCViewController *)[[UIStoryboard storyboardWithName:@"Main" bundle:NULL] instantiateViewControllerWithIdentifier:@"ReactNativeVC"];

  [[self navigationController] pushViewController:rootViewController animated:YES];
}

// ReactNativeViewObjC.h 

#import "ReactNativeObjCViewController.h"

#import "ReactNativeViewObjC.h"

@interface ReactNativeObjCViewController ()
@property (weak, nonatomic) IBOutlet ReactNativeViewObjC *reactViewWrapper;

@end

@implementation ReactNativeObjCViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  self.title = @"React Wrapper (Obj C)";


  self.reactViewWrapper.data = [@{
                                  @"content": @"Welcome to React Native"
                                  } mutableCopy];

  [self.reactViewWrapper initializeReactView];


}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}

// index.ios.js 

#import <UIKit/UIKit.h>

@interface ReactNativeViewObjC : UIView

- (void) initializeReactView;
@end

//ReactNativeViewObjC.m

#import "ReactNativeViewObjC.h"

#import "RCTBundleURLProvider.h"

-(void) initializeReactView {


  NSURL *jsCodeLocation;

  jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

  RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation moduleName:@"devdactic_tabs" initialProperties:nil
      launchOptions:nil];
  rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];

  rootView.translatesAutoresizingMaskIntoConstraints = NO;

  constraints = [constraints arrayByAddingObjectsFromArray:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-0-[rootView]-0-|" options:0 metrics:nil views:views]];

  [self addConstraints:constraints];
  [self layoutIfNeeded];
}
