react native 原生事件发送

属性事件添加

@interface MyView : UIView
/// 提供给JS使用的属性

@property (nonatomic, copy) RCTBubblingEventBlock onChange;

属性暴漏

@interface RCTMyViewManager()   <MBMapViewDelegate,MBGpsLocationDelegate,MBReverseGeocodeDelegate,UIAlertViewDelegate>
@end
@implementation RCTMyViewManager
@synthesize bridge = _bridge;

RCT_EXPORT_MODULE()
RCT_EXPORT_VIEW_PROPERTY(onChange,RCTBubblingEventBlock)

属性对应

export default class MyView extends React.Component {    
// 与    OC中 RCTViewManager子类中导出的属性对应  
  static propTypes     = {   onChange: React.PropTypes.func,
 };

js中调用监听方法

onchange(event){    
console.log('————————————————————    e'+event.nativeEvent.location);
}
 <MyView     
  ref="theMyView"   
 style={styles.private}    
  forbidGesture = {false}     
  zoomLevel = {10}    
 onChange = {(event) => this.onchange(event)}   
/>
