React native 调用原生接口实现起来比较简单，自定义接口类PushManager，需要实现RCTBridgeModule协议，导入RCT_EXPORT_MODULE宏定义.
#import <Foundation/Foundation.h>
#import <React/RCTBridgeModule.h>
#import <React/RCTLog.h>
@interface PushManager : NSObject<RCTBridgeModule>
@end
#import "PushManager.h"
@implementation PushManager
RCT_EXPORT_MODULE();
- (NSDictionary *)baseInfomation {
return @{ @"name": @"FlyElephant" };
}
RCT_EXPORT_METHOD(showMessage:(NSString *)message type:(NSString *)type)
{
RCTLogInfo(@"FlyElephant 本地调用 %@---%@---", message, type);
}
@end
React native导入本地原生模块:
import {
Text,
View,
TouchableHighlight,
NativeModules,
NativeEventEmitter,
} from 'react-native';
const PushManager = NativeModules.PushManager;
调用原生模块方法:
PushManager.showMessage("消息推送","local");
原生模块还支持回调函数的调用，iOS提供回调方法:
RCT_EXPORT_METHOD(blockCallbackEvent:(RCTResponseSenderBlock)callback)
{
NSArray *events=@[@"Callback ", @"Block ", @"FlyElephant"];
callback(@[[NSNull null],events]);
}
JavaScript回调处理:
PushManager.blockCallbackEvent((error, events) => {
if (error) {
console.error(error);
} else {
console.log("回调结果:" + events);
}
});
