I have been trying to use the Settings.bundle as the store for options using PSMultiValueSpecifier which will allow a user to select one of them. So I need to be able to add NEW options in the Settings.bundle. Seemed easy enough.
Here is a sample of the PSMultiValueSpecifier in the Root.plist
<key>Type</key>
<string>PSMultiValueSpecifier</string>
<key>Title</key>
<string>Options</string>
<key>DefaultValue</key>
<string></string>
<key>Key</key>
<string>optionSelection_preference</string>
<key>Values</key>
<array>
<string>option_1_key</string>
</array>
<key>Titles</key>
<array>
<string>Option 1</string>
</array>
So I am trying to add 'Option 2' and it's key. So I wrote the following code (partial):
NSDictionary* rootPlist = [NSDictionary dictionaryWithContentsOfFile:settingsBundle];
if (rootPlist == nil)
return NO;
NSArray* specifiers = [rootPlist objectForKey:@"PreferenceSpecifiers"];
NSMutableDictionary *multiValueSpecifier = nil;
for (NSMutableDictionary *specifier in specifiers)
{
if ([[specifier objectForKey:@"Key"] isEqualToString:speficierKey] == YES && [[specifier objectForKey:@"Type"] isEqualToString:@"PSMultiValueSpecifier"] == YES)
{
multiValueSpecifier = specifier;
break;
}
}
if (multiValueSpecifier == nil)
return NO;
NSMutableArray* titlesArray = [[multiValueSpecifier objectForKey:@"Titles"] mutableCopy];
NSMutableArray* valuesArray = [[multiValueSpecifier objectForKey:@"Values"] mutableCopy];
[titlesArray addObject:title];
[valuesArray addObject:value];
[multiValueSpecifier setObject:titlesArray forKey:@"Titles"];
[multiValueSpecifier setObject:valuesArray forKey:@"Values"];
return [rootPlist writeToFile:settingsBundle atomically:YES];
The code seems to work and I see the changes in the Settings.bundle.
PROBLEM: When re-loaded, the new entry is gone, and only the entry added from XCode remains.
