问题 I have created a react native app, by which I need compare from and to date. And if it's true, execution will be done. The problem is, the condition works in react native development mode and not working in react native production release. I am using firebase for the database, also using redux. Here is my code: var d = new Date(); const fromDate = extract.validFrom.split("-").reverse(); //"01-02-2019" const tillDate = extract.validTill.split("-").reverse(); //"10-03-2019" var k = new Date

问题 I am attempting to put the following animation in an infinite loop until a particular state occurs: class MyModal extends Component { constructor() { super() this.springValue = new Animated.Value(0.3) } spring = () => { this.springValue.setValue(0.3) Animated.spring( this.springValue, { toValue: 1, friction: 1, tension: 1, duration:5000 } ).start() } componentDidMount() { this.spring() } render() { return ( <View> <Modal animationType="none" transparent={false} visible={this.state

问题 I have a React Native (0.59) app which consumes an (Swagger-generated) SDK that accepts Blob objects for file uploads. While there are sources on creating blobs from remote resources (e.g. using fetch), I couldn't find any resource on creating a blob on the fly. For example I have a string (regular JS string), and I need to upload that string as a text file to the server. I'll also have other file references from the file system where I'll also need to upload too. How do I create Blob from

问题 I need to create an animation with an image that will circle around another image. I have already tried to use suggestions from a similar question like Animate a Circle around another circle , but unfortunately it didn't help. I tried looking into 3rd party modules that would offer the desirable functionality, but haven't found something that would fit my need. I found a helpful article to understand the circular motion in JavaScript, however I have a hard time to replicate it in React Native
