React-Native “react-native run-ios”

-

I installed a fresh react-native app.I keep getting the below error when I ran react-native run-ios

Incorrect hash:

eb7c61ff0c1c55cd85deb3c15f2731c14c787429 ?/Users/johndoe/.rncache/boost_1_63_0.tar.gz

I have tried react-native upgrade, rm -rf node_modules

Still doesn't work.

  1. Check this error using simulator app and real device.
  2. Upgrade Xcode to currently latest version.

Otherwise use create-react-native-app. That way you can run app both device and simulator, which is great case if you don't need to detach your app.

I just resolve it, this problem is the version of boost wrong in start scripts.

  1. Go to https://github.com/facebook/react-native/blob/0.56-stable/scripts/ios-install-third-party.sh and select the branch your rn version.

  2. Drag to the bottom and go to the url such as https://github.com/react-native-community/boost-for-react-native/releases/download/v1.63.0-0/boost_1_63_0.tar.gz

  3. Copy the download file to ~/.rncache, replace the old one.

  4. Restart.

Done!

Run this command to freshen up everything and pray twice facing the north.

watchman watch-del-all && rm -rf $TMPDIR/react-* && rm -rf node_modules/ && npm cache verify && npm install && npm start -- --reset-cache

Meaning of `{}` for return expression

-
15 1 I found by accident that the following compiles: #include <string> #include <iostream> class A{ int i{}; std::string s{}; public: A(int _i, const std::string& _s) : i(_i), s(_s) { puts("Called A(int, const std::string)"); } }; A foo(int k, const char* cstr){ return {k, cstr}; // (*) } int main(){ auto a = foo(10, "Hi!"); return 0; } The line of interest is (*). I guess the function foo is equivalent to: A foo(int k, const char* str){ return A(k, cstr); } However, is there a special name for this mechanism in (*)? Or is it just the simple fact that the compiler knows which constructor to call due to the return type? ...

Get current scroll position of ScrollView in React Native

-
Is it possible to get the current scroll position, or the current page of a <ScrollView> component in React Native? So something like: <ScrollView horizontal={true} pagingEnabled={true} onScrollAnimationEnd={() => { // get this scrollview's current page or x/y scroll position }}> this.state.data.map(function(e, i) { <ImageCt key={i}></ImageCt> }) </ScrollView> Try. <ScrollView onScroll={this.handleScroll} /> And then: handleScroll: function(event: Object) { console.log(event.nativeEvent.contentOffset.y); }, Disclaimer: what follows is primarily the result of my own experimentation in React Native 0.50. The ScrollView documentation is currently missing a lot of the information covered below; for instance onScrollEndDrag is completely undocumented. Since everything here relies upon undocumented behaviour, I can unfortunately make no promises that this information will remain correct a ...
