接触iOS开发时间不长，最近有一个需求，要从APP内部调用系统分享，把相册里的几张照片分享到小红书，照片是从相册里读取的。我按照网上的教程（UIActivityViewController）写完之后，发现我分享两张不同的照片A和B到小红书，小红书上显示的确实两张一样的照片A、A，我试了下其他的APP，iPhone的系统相册是正常的，时光相册是正常的，腾讯相册管家分享的效果跟我的一样是重复的。另外，我试了我自己的代码分享到除了小红书以外的平台是正常的，比如微信、QQ、备忘录等。实在是不能理解为什么，网上也没找到类似的问题。到底是我写的代码问题还是小红书的问题。希望有经验的开发者能给解答一下，十分感谢。
static func sharePhotosToXHS(photos: Array<String>) {
DispatchQueue.main.async {
var items = Array<Any>()
// 遍历图片路径
for photo in photos {
if let image = UIImage(contentsOfFile: photo) {
// 压缩图片
if let imageCompressed = UIImage(data: image.compressImage(size: .one)) {
items.append(MyImageItemProvider(image: imageCompressed))
}
}
}
let activityVC = UIActivityViewController(activityItems: items, applicationActivities: nil)
activityVC.excludedActivityTypes = [
