OC檔案：

————————TestManager.h——————

#import <UIKit/UIKit.h>

#import <Foundation/Foundation.h>

#import "RCTBridgeModule.h"

@interface TestManager : NSObject <RCTBridgeModule>

@end

————————TestManager.m——————

#import "TestManager.h"

@implementation TestManager

RCT_EXPORT_MODULE();

RCT_EXPORT_METHOD(addEvent:(NSString *)name location:(NSString *)location)

{

NSLog(@"Pretending to create an event %@ at %@", name, location);

UIView *view = [[UIViewalloc] initWithFrame:CGRectMake(0, 0, 200, 200)];

  view.backgroundColor

dispatch_async(dispatch_get_main_queue(), ^{

    [[UIApplicationsharedApplication].keyWindowaddSubview:view];

  });

}

@end

JS使用：

import {
  NativeModules,
} from 'react-native';

   testMethod() {
    TestManager.addEvent('Test', 'Test Demo');
  }
