launchImageLibrary not working on iPhone emulator

react-native-cli: 2.0.1 react-native: 0.40.0 “react-native-image-picker”: “^0.25.1”,

It works fine on Android, but when I run it in the iOS emulator or physical iphone device I get this error:

undefined is not a function (evaluating ‘_reactNativeImagePicker2.default.launchImageLibrary(options, function(response){ })’)

Here is the stripped down version of my source code:

import ImagePicker from 'react-native-image-picker';

class EditListing extends Component {
    pickImage(imageType){
	let options = {
		mediaType: 'photo',
		quality: 1,
		maxWidth: 144,
		maxHeight: 144
	}

	ImagePicker.launchImageLibrary(options, (response) => {
		...
	});
    }
   ...
}

The only thing different I can think of is that when I linked the binary with the library, I could only find “libRNImagePicker.a” (instead of “RNImagePicker.a” like the documentation states.)

install it manually, do not use auto link command line

No problem @cosydney. In the readme file, refer to the manual iOS installation instructions. It talks about manually linking up libraries in your Xcode project. I undid all of that and then walked through the steps again and it worked that time. I must have just done it wrong the first time.
