成功上传图片后，上传的图片需要时间显示吗？有人知道吗？
这是我的代码
_onPressEdit = () => {
ImagePicker.showImagePicker(options, response => {
console.log('Response = ', response);
if (response.didCancel) {
console.log('User cancelled image picker');
} else if (response.error) {
console.log('ImagePicker Error: ', response.error);
} else if (response.customButton) {
console.log('User tapped custom button: ', response.customButton);
} else {
this._uploadImage(response.uri);
}
});
};这是我的完整代码
