react-native-image-picker 上传ios实

1.安装HEIC转化JPG：react-native-heic-converter

https://github.com/maxim-kolesnikov/react-native-heic-converter

npm install react-native-heic-converter --save

react-native link react-native-heic-converter

2.源代码

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

import RNHeicConverter from 'react-native-heic-converter';

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

    if (response.didCancel) {

        console.log('User cancelled image picker');

    } else if (response.error) {

        console.log('ImagePicker Error: ', response.error);

    } else {

        let source = {}

        //判断是不是HEIC文件

        if (Platform.OS === 'ios' && (response.fileName.endsWith('.heic') || response.fileName.endsWith('.HEIC'))) {

            //根据origURL转换成JPG图片： 这有个雷区，刚开始使用的response.uri.在IOS中uri的heic文件后缀也是JPG，所以不能使用。查看API后，应该使用origURL。（origURLT：he URL of the original asset in photo library, if it exists）

            RNHeicConverter.convert({ path: response.origURL }).then((data) => {

                const { success, path, error } = data

                if(!error && success && path) {

                    let name = response.fileName

                    name = name.replace(".heic", ".jpg")

                    name = name.replace(".HEIC", ".jpg")

                    source = {uri: path, name}

                    this.handleChange(source)

                    this.setState({ loading: false });

                } else {

                    Toast.show({text: "heic类型转jpg失败!"});

                }

            });

        } else {

                source = {uri: response.uri, type: response.type, name: response.fileName}

                this.handleChange(source) this.setState({ loading: false });

        }

}

});
