如何在
Swift中将事件发送到
JavaScript？
有一些Objc代码示例如何将事件发送到JavaScript,但我需要在swift中做什么？
#import "RCTBridge.h"
#import "RCTEventDispatcher.h"
@implementation CalendarManager
@synthesize bridge = _bridge;
- (void)calendarEventReminderReceived:(NSNotification *)notification
{
NSString *eventName = notification.userInfo[@"name"];
[self.bridge.eventDispatcher sendAppEventWithName:@"EventReminder"
body:@{@"name": eventName}];
}
@end
我只是想弄清楚自己.这实际上非常简单.继承人我是怎么做到的：
原文链接：https://www.f2er.com/swift/318718.htmlEventTests.m
#import "RCTBridgeModule.h" @interface RCT_EXTERN_MODULE(EventTests,NSObject) RCT_EXTERN_METHOD( testEvent:(NSString *)eventName ) @end
EventTests.Swift
import UIKit
@objc( EventTests )
class EventTests: NSObject {
// Swift doesn't have synthesize - just define the variable
var bridge: RCTBridge!
@objc func testEvent( eventName: String ) {
self.bridge.eventDispatcher.sendAppEventWithName( eventName,body: "Woot!" )
}
}
MyModule.js
var React = require( 'react-native' );
var EventTests = require( 'NativeModules' ).EventTests;
var {
Component,NativeAppEventEmitter
} = React;
var testEventName = 'test';
class MyModule extends Component {
constructor( options ) {
super( options );
// Register for our test event
NativeAppEventEmitter.addListener( testEventName,( body ) => {
console.log( body );
});
// Call objective c function,which will emit our test event
EventTests.testEvent( testEventName );
}
}
module.exports = MyModule;
还要确保在桥接标头中包含一些导入：
#import "RCTBridge.h" #import "RCTEventDispatcher.h"
