1.安裝HEIC轉(zhuǎn)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.源代碼

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 = {}

? ????? //判斷是不是HEIC文件

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

? ? ? ? ? ? //根據(jù)origURL轉(zhuǎn)換成JPG圖片： 這有個雷區(qū)，剛開始使用的response.uri.在IOS中uri的heic文件后綴也是JPG，所以不能使用。查看API后，應該使用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類型轉(zhuǎn)jpg失敗!"});

????????????????}

????????????});

? ? ? ? } else {

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

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

????????}

}

});
