Popup组件能不能暴露出一个方法，给外部节点点击调用呢

[NikFranki]

<Popup className="fortest" transitionName="rmc-picker-popup-slide-fade" maskTransitionName="rmc-picker-popup-fade" content={popupContent} title="Picker" disabled={this.state.disabled} onDismiss={this.onDismiss} onOk={this.onOk} value={this.state.value} > {'open'} </Popup> 源码貌似把点击方法绑定到button上了
