react nativeScrollview在某些时候滚动无效

今天在使用Scrollview的时候滚动没有效果，直接上代码：

   return(<View style={{flex:1}}>        <NavigatorHeader nav={this.props.nav} title="首页"></NavigatorHeader>        <HomeCategory nav={this.props.nav} ClickCallback={this.props.ClickCallback}></HomeCategory>     <ScrollView showsVerticalScrollIndicator={false}>       <HomeSwiper nav={this.props.nav}/>       <HomePictureTitleText textTittle1={'卫视热播'} navigatior={this.props.nav} parentCode={'0909112305914'}/>       <HomePictureTitleText textTittle1={'热门精选'} navigatior={this.props.nav} parentCode={'0909112423500'}/>       <HomePictureTitleText textTittle1={'猜你喜欢'} navigatior={this.props.nav} parentCode={'0909112654380'}/>       <HomePictureTitleText textTittle1={'为我推荐'} navigatior={this.props.nav} parentCode={'0909112712867'}/>          </ScrollView></View>   );

怎么样都不能滚动。

后在scrollview中最后加入一个空的布局就能滚动了：

在此做个记录：

   return(<View style={{flex:1}}>        <NavigatorHeader nav={this.props.nav} title="首页"></NavigatorHeader>        <HomeCategory nav={this.props.nav} ClickCallback={this.props.ClickCallback}></HomeCategory>     <ScrollView showsVerticalScrollIndicator={false}>       <HomeSwiper nav={this.props.nav}/>       <HomePictureTitleText textTittle1={'卫视热播'} navigatior={this.props.nav} parentCode={'0909112305914'}/>       <HomePictureTitleText textTittle1={'热门精选'} navigatior={this.props.nav} parentCode={'0909112423500'}/>       <HomePictureTitleText textTittle1={'猜你喜欢'} navigatior={this.props.nav} parentCode={'0909112654380'}/>       <HomePictureTitleText textTittle1={'为我推荐'} navigatior={this.props.nav} parentCode={'0909112712867'}/>         <View style={{height:Platform.OS == 'ios' ? 0:30,}}></View>   </ScrollView></View>   );

做个问题具体的原因我现在也不清楚，有知道的麻烦告知一下。谢谢
