        <TouchableOpacity style={styles.recDelete }>
          <Icon name="eye"
            size={24}
            color='white'
            onPress={
             onShowPopup
             this.setstate({mitem:item.cin})}/>
            <AfficheRec 
            title="R├ęclamation"
            ref={(target)=>popupRef=target}
