FileDialog on iOS only works in portrait mode. Crashes otherwise.

Dogmaphobic

If I set FileDialog's folder to shortcuts.pictures when the app is in landscape mode, it flips to portrait mode before showing the OS builtin image picker. If the app is set to only use Landscape mode, Qt crashes:

MyApp[808:282060] *** Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and [PUUIAlbumListViewController shouldAutorotate] is returning YES'

Is this a bug or am I missing something?

Hi,

Can you provide a minimal compilable example that shows that behavior ?

@SGaist Just create anything using Qt Creator's wizard:

main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);
    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
    return app.exec();
}

main.qml

import QtQuick 2.7
import QtQuick.Window 2.2
import QtQuick.Dialogs  1.2
import QtQuick.Controls 1.3

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    FileDialog {
        id:             filePicker
        title:          "Please choose an image file"
        folder:         shortcuts.pictures
        visible:        false
        nameFilters:    [ "Image files (*.jpg *.png)", "All files (*)" ]
        onAccepted: {
            console.log("You picked: " + filePicker.fileUrl()
            filePicker.close()
        }
    }
    Button {
        anchors.centerIn: parent
        text: "Pick An Image"
        onClicked: {
            filePicker.open()
        }
    }
}

Note that you need to add some keys to the .plist file. Either through Xcode or creating your own .plist and adding to your .pro file.

	<key>NSPhotoLibraryUsageDescription</key>
	<string>Foo Bar</string>
	<key>UISupportedInterfaceOrientations</key>
	<array>
		<string>UIInterfaceOrientationLandscapeLeft</string>
		<string>UIInterfaceOrientationLandscapeRight</string>
	</array>

Everything using the latest version (Qt Creator 4.1.0, Qt 5.7, Xcode 8.0, etc.)

Sorry, I couldn't test.

Since there has been new releases in between can you check with them ? 5.7.1 is out and 5.8 Beta also.
