      borderColor:'#eeeeee',
        borderWidth:1,

        padding:10

        width:60,
        height:60,
        marginRight:10
    },
    titleStyle:{
        width:width*0.7,
        color:'red',
        fontSize:15,
        marginBottom:10
    }

});

AppRegistry.registerComponent('helloworld', () => helloworld);

这里注意onPress={()=>AlertIOS.alert('点击了第'+rowID+'行')的写法，如果没有()=>会有调用问题，具体原因以后会研究吧
