响应本地图像uri和异步存储

Question

我试图保存一个个人资料图片，我保存它与asyncStorage。存储部分工作完美，但如果我关闭应用程序并重新打开它不显示图像。

i logging image uri，有uri但不能解决问题

这是我的代码

这是图像选取部分

const ImagePick = async () => {
const options = {
title: 'Seçim yapınız.',
cancelButtonTitle: 'İptal',
takePhotoButtonTitle: 'Bir fotoğraf çek',
chooseFromLibraryButtonTitle: 'Galeriden seç',
chooseWhichLibraryTitle: 'Galeriden seç',
mediaType: 'photo',
storageOptions: {skipBackup: true, path: 'images'},
};
let isCameraPermitted = await requestCameraPermission();
let isStoragePermitted = await requestExternalWritePermission();
if (isCameraPermitted && isStoragePermitted) {
ImagePicker.showImagePicker(options, async response => {
//console.log('response', response);
if (response.didCancel) {
console.log('Kullanıcı fotoğraf seçimini iptal etti');
} else if (response.customButton) {
console.log('Özel butona tıklandı.');
} else if (response.error) {
console.log('error', 'Bir hata oluştu.');
} else {
console.log(response.fileName);
let uri = response.uri;
let path = response.uri;
if (Platform.OS === 'ios') {
path = '~' + path.substring(path.indexOf('/Documents'));
}
if (!response.fileName) {
response.fileName = path.split('/').pop();
}
let name = response.fileName;
let type = `image/${name.split('.').slice(-1)[0]}`;
console.log('uri', uri);
console.log('name', name);
console.log('type', type);
setImageUri(response.uri);
try {
await AsyncStorage.setItem('profilePicture', response.uri);
console.log('async storage kayıt başarılı');
} catch (error) {
console.log(error);
}
}
});
}
};

我得到这样的图像

useEffect(() => {
getProfilePicture();
}, []);
const getProfilePicture = async () => {
const profilePicture = await AsyncStorage.getItem('profilePicture');
console.log('profilePicture', profilePicture);
if (profilePicture !== null) {
setImageUri(profilePicture);
setIsLoading(false);
} else {
setImageUri(
'https://t3.ftcdn.net/jpg/03/46/83/96/360_F_346839683_6nAPzbhpSkIpb8pmAwufkC7c5eD7wYws.jpg',
);
setIsLoading(false);
}
};
