MBProgressHUD for ReactNative

readme.md

#How to use

• Add pod 'MBProgressHUD', '~> 1.1.0' to your pod file and run pod install
• Copy ProgressIndicator.swift and ProgressIndicator.m files to your xcode project.
• If your project based on Swift you may need to add #import "MBProgressHUD.h" to the BridgingHeader file
• See the sample use in hello.screen.js

hello.screen.js

import {
  NativeModules,
} from 'react-native';

useLayoutEffect(() => {
    if (isLoading) {
      NativeModules.ProgressIndicator.show('Signing in');
      return;
    }
    NativeModules.ProgressIndicator.hide();
  }, [isLoading]);

ProgressIndicator.h

#import "React/RCTBridgeModule.h"

@interface RCT_EXTERN_MODULE(ProgressIndicator, NSObject)
RCT_EXTERN_METHOD(show:(NSString *)text)
RCT_EXTERN_METHOD(hide)
@end
