【问题描述】：

我正在尝试使用 Qt 打开 ios 图库，我发现了很多文章和答案。我测试了它们，但它们在 ios(10) 中不起作用这里有两个不适合我的链接

Link 1 : Open ios gallery with FileDialog{}

Link 2 : Mixing Objective-c with Qt to access gallery in ios

第一个链接解释了如何使用 FileDialog 打开画廊，根据链接和它的描述：

在 iOS 中，只需在 QML 文件中创建一个 FileDialog 并设置文件夹：快捷方式.图片。它将调用 iOS 库。

。下面是我的代码，但它不起作用！

import QtQuick 2.7
import QtQuick.Controls 2.0
import QtQuick.Dialogs 1.0


ApplicationWindow {
    visible: true
    width: 640
    height: 480

    FileDialog {
        id: fileDialog
        visible: true
        folder: shortcuts.pictures

    }

}

第二个链接，我无法编译它，我得到了这个错误

ld: '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphonesimulator.a(arclite.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

** BUILD FAILED **


The following build commands failed:
    Ld Debug-iphonesimulator/QuickIOSExample.app/QuickIOSExample normal x86_64
(1 failure)
make: *** [xcodebuild-debug-simulator] Error 65
14:05:48: The process "/usr/bin/make" exited with code 2.

    function checkDuplicate(url){
        for(var i=0;i<picListModel.count;i++) {
            if(picListModel.get(i).fileName===url)
                return true;
        }
