1、直接使用Native Modules 组件
- “MyCustomModule”其实就是我们的对应的OC工程中的类,“processString“就是类中的方法
/**
* 调用iOS模块1
* http://www.cnblogs.com/daomul/
*/
'use strict';
var React = require('react-native');
var { NativeModules,View, Text,ScrollView,StyleSheet,TouchableOpacity } = React;
var Message = React.createClass({
getInitialState() {
return { text: 'Goodbye World.' };
},
componentDidMount() {
NativeModules.MyCustomModule.processString(this.state.text, (text) => {
this.setState({text});
});
},
render: function() {
return (
<ScrollView style={styles.view}>
<Text>{this.state.text}</Text>
</ScrollView>
);
},
});
var styles = StyleSheet.create({
view:{margin:20,},
});
React.AppRegistry.registerComponent('HellWorld', () => Message);
- 所以对应OC工程中的实现:通过RCT_EXPORT_MODULE() 似的JS能够放开OC中的API,与之通信调用
#import <Foundation/Foundation.h>
#import "RCTBridgeModule.h"
@interface MyCustomModule : NSObject <RCTBridgeModule>
@end
#import "MyCustomModule.h"
@implementation MyCustomModule
RCT_EXPORT_MODULE();
RCT_EXPORT_METHOD(processString:(NSString *)input callback:(RCTResponseSenderBlock)callback)
{
callback(@[[input stringByReplacingOccurrencesOfString:@"Goodbye" withString:@"Hello"]]);
}
@end
2、引入Native Modules的方式
- 我们还可以通过引入NativeModules的方式“CalendarVIew”对应的也是OC类名,addEventWithName是方法名
var CalendarManager = require('NativeModules').CalendarVIew;
CalendarManager.addEventWithName('something need to remmber','ShenZheng NanShan');
- 如果参数很多我们希望通过NSDictionary来传递数据,也是可以的,OC端可以做一下Convert的处理:
CalendarManager.addEventWithName('something need to remmber',{
location: 'ShenZhen NanShan',
description: 'other thingslo'
});
#import "CalendarVIew.h"
#import "RCTConvert.h"
#import "RCTLog.h"
@implementation CalendarVIew
RCT_EXPORT_MODULE();
RCT_EXPORT_METHOD(addEventWithName:(NSString *)name dic:(NSDictionary *)dic)
{
NSString *localStr = [RCTConvert NSString:dic[@"location"]];
NSString *descStr = [RCTConvert NSString:dic[@"description"]];
RCTLogInfo(@"the name is %@,and the location is %@,%@",name,localStr,descStr);
}
