I'm using Axios to retrieve my data from my API in this Class component in TSX. It doesn't give any error, it just doesn't show my Images or not even the data in a console.log. I'm now using a class component with tsx because in my previous attempts to let a animated slider work I used: Class component in jsx, Class component in tsx, Function in JSX with hooks aswell in TSX. At every attempt there were different errors that I couldn't solve that's why I'm using this strategy now and I guess I'm close now to the sollution, it's just the Data that's not viewing.
Thanks in advance

CodePudding user response：
Try this way by using state for reflecting changes after API respond
class MyComponent extends Component {
state = {
imagesData: [],
};
// rest of the code remains the same
componentDidMount() {
axios.get(`xxxxxx`).then((res) => {
const imagesData = res.data;
this.setState({ imagesData });
});
}
renderUsers = () => {
if (this.state.imagesData) {
return this.state.imagesData.map((item, i) => {}).reverse();
}
};
render() {
return <View></View>;
}
}
