[SOLVED]Working with iOS Settings.bundle preferences

DRoscoe

Here's what I have so far, but it's not working..

  QSettings settings(QGuiApplication::applicationDirPath() + "/Settings.bundle/Root.plist", QSettings::NativeFormat, &app);

  if (settings.contains("Title"))
  {
    qDebug() << "FOUND TITLE";
  }

The qDebug() statement is never getting hit

Hi,

The question might seem silly but are you sure you are looking in the right place for the Settings.bundle folder ?

DRoscoe

I verified that the output from:

QGuiApplication::applicationDirPath()+ "/Settings.bundle/Root.plist"

leads to the correct location. I put a qDebug() statement to the console to display the path and then followed it from a terminal window

SGaist

Can you share the content of Root.plist ?

DRoscoe

Sure! Here it is:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>PreferenceSpecifiers</key>
	<array>
		<dict>
			<key>Type</key>
			<string>PSTextFieldSpecifier</string>
			<key>Title</key>
			<string>TAP Engine Hostname: </string>
			<key>DefaultValue</key>
			<string>localhost</string>
			<key>Key</key>
			<string>engineHostname</string>
		</dict>
	</array>
	<key>StringsTable</key>
	<string>Root</string>
</dict>
</plist>

Ok, Title is a key in a dict in an array so you have to retrieve following that way (long way):

QVariantList preferenceSpecifiers = settings.value("PreferenceSpecifiers").toList();
QVariant preferenceSpecifier = preferenceSpecifiers.first();
QVariantMap preferenceSpecifierContent = preferenceSpecifier.toMap();

// Now you can retrieve Title and the rest

Short version:
QString title = settings.value("PreferenceSpecifiers").toList().first().toMap().value("Title").toString();

@SGaist That did the trick. Thank you very much!

@SGaist Ok, it seems I have hit a wall. I don't know how to look up the value of "engineHostname" since its not a key. Just reading the .plist isn't enough since the actual values don't seem to be stored there. For example, I installed the app on my iPad and set the Engine Hostname to "Joe" in the Settings app. The thing is, I don't know how to get that value back. The .plist does not seem to store this value. It's somewhere else and I can't seem to figure out a "Qt way" to get to it. Do I have to add a .mm file to my project and make calls through NSUserDefaults?

SGaist

I may be wrong but in your example, engineHostname is the value for the key "Key". Shouldn't engineHostname be the key ?
