这是react-native自带的生成图片的属性,所以使用之前只需要引用UIManager属性即可;

View生成图片:

state = {
uri: null
}; takeToImage() {
UIManager.takeSnapshot(this.refs.location, {format: 'png', quality: 0.8}).then(
(uri) => this.setState({uri})
).catch(
(error) => alert(error)
);
} render() {
return (<View>
<View ref='location'>
<Text>东经</Text>
<Text>东经</Text>
<Text>西经</Text>
<Text>东经</Text>
</View> <Text onPress={()=>this.takeToImage()}>生成图片</Text> <Image source={{uri: this.state.uri}} style={{borderWidth:1,height:50,width:300}}/>
</View>
)
}
