javascript - react 原生 : Call method of RCTViewManager and Render a View
<p><p>在 React Native 中，是否可以渲染 RCTBridgeModule 的 UIView 并调用此 Module 的方法？
下面我发布了我用两种方法创建的模块。但我不知道它是否正确:</p>
<p>RCTAugmentPlayerManager.h</p>
<pre><code>#import "RCTBridgeModule.h"
@interface RCTAugmentPlayerManager : NSObject <RCTBridgeModule>
@end
</code></pre>
<p>RCTAugmentPlayerManager.m</p>
<pre><code>@implementation RCTAugmentPlayerManager
RCT_EXPORT_MODULE();
// Method which execute treatment
RCT_EXPORT_METHOD(oneMethod:(NSString *)name )
{
RCTLogInfo(@"Display name %@", name);
}
// Method which return a view to render in Javascript
RCT_EXPORT_METHOD(methodWithReturnView)
{
UIView * view = [ init];
return view;
}
@end
</code></pre>
<p>AugmentPlayer.js</p>
<pre><code>import { NativeModules } from 'react-native';
var RCTAugmentPlayerManager = NativeModules.RCTAugmentPlayerManager;
</code></pre>
<p>index.ios.js</p>
<pre><code>import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View,
NativeModules
} from 'react-native';
class mobileApp extends Component {
constructor(props){
super(props);
var augment = NativeModules.AugmentPlayer;
augment.oneMethod('test');
}
render() {
return (
<View style={{height:200, width:200}}>
{AugmentPlayer.methodWithReturnView}
</View>
);
}
}
AppRegistry.registerComponent('mobileApp', () => mobileApp);
</code></pre>
<p>谢谢</p></p>

<p><p><strong>TL;DR:</strong>不，你不能。</p>
<p>要渲染 <code>UIView</code>，您必须继承 <code>RCTViewManager</code> 并在 <code>view</code> 方法中返回您的 View :</p>
<pre><code>@interface MyCoolViewManager: RCTViewManager
@end
@implementation MyCoolViewManager
RCT_EXPORT_MODULE()
-(UIView *)view {
return ;
}
@end
</code></pre>
<p>有关更多信息，请参阅文档，其中非常详细地说明了您需要做什么:</p>
