React native学习第十一章:Modal

Modal组件可以用来覆盖包含React Native根视图的原生视图（如UIViewController，Activity）。

在嵌入React Native的混合应用中可以使用Modal。Modal可以使你应用中RN编写的那部分内容覆盖在原生视图上显示。import React, { Component } from 'react';
 

import React, { Component } from 'react';
import { Modal, Text, TouchableHighlight, View ,AppRegistry} from 'react-native';

class ModalExample extends Component {

  constructor(props) {
    super(props);
    this.state = {modalVisible: true};
  }

  setModalVisible(visible) {
    this.setState({modalVisible: visible});
  }

  render() {
    return (
      
         {alert("Modal has been closed.")}}
          >
         
          
            Hello World!

             {
              this.setModalVisible(!this.state.modalVisible)
            }}>
              Hide Modal
            

          
         
        

         {
          this.setModalVisible(true)
        }}>
          Show Modal
        

      
    );
  }
}
AppRegistry.registerComponent('TestModal', () => ModalExample);

   NSURL *jsCodeLocation;
    //
    jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"TestModal" fallbackResource:nil];
    
    //    NSURL *jsCodeLocation = [NSURL
    //                            URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios"];
    //    RCTRootView *rootView =
    //    [[RCTRootView alloc] initWithBundleURL : jsCodeLocation
    //                         moduleName        : @"TextActivity"
    //                         initialProperties :
    //     @{
    //       @"scores" : @[
    //               @{
    //                   @"name" : @"Alex",
    //                   @"value": @"42"
    //                   },
    //               @{
    //                   @"name" : @"Joel",
    //                   @"value": @"10"
    //                   }
    //               ]
    //       }
    //                          launchOptions    : nil];
    RCTRootView *rootView =
    [[RCTRootView alloc] initWithBundleURL : jsCodeLocation
                         moduleName        : @"TestModal"
                         initialProperties :nil launchOptions    : nil];
//    UIViewController *vc = [[UIViewController alloc] init];
//    vc.view = rootView;
//    [self presentViewController:vc animated:YES completion:nil];
    [self.view addSubview:rootView];

animationType PropTypes.oneOf(['none', 'slide', 'fade'])

The animationType prop controls how the modal animates.

• slide slides in from the bottom
• fade fades into view
• none appears without an animation

onRequestClose Platform.OS === 'android' ? PropTypes.func.isRequired : PropTypes.func

The onRequestClose prop allows passing a function that will be called once the modal has been dismissed.

On the Android platform, this is a required function.

onShow function

The onShow prop allows passing a function that will be called once the modal has been shown.

transparent bool

The transparent prop determines whether your modal will fill the entire view. Setting this to true will render the modal over a transparent background.

visible bool

The visible prop determines whether your modal is visible.

onOrientationChange PropTypes.func

The onOrientationChange callback is called when the orientation changes while the modal is being displayed. The orientation provided is only 'portrait' or 'landscape'. This callback is also called on initial render, regardless of the current orientation.

supportedOrientations PropTypes.arrayOf(PropTypes.oneOf(['portrait', 'portrait-upside-down', 'landscape', 'landscape-left', 'landscape-right']))

The supportedOrientations prop allows the modal to be rotated to any of the specified orientations. On iOS, the modal is still restricted by what's specified in your app's Info.plist's UISupportedInterfaceOrientations field.
