I have a controller object "Controller" of Class Name "AdBlockerPreferences",
with the outlet connected to the Array Controller. the Array Controller's
content is bound to Controller.subscriptions
the Array Controller has the preference "Prepares Content" checked.
.....I also have File's Owner with the Class identity of "AdBlockerPreferences"
could this be my problem?
in my AdBlockerPreferences.h file just the relevant stuff:
AdBlockerPreferences : NSPreferencesModule
{
IBOutlet id subscriptionTableView;
IBOutlet id subscriptionsArrayController;
NSMutableArray* subscriptions;
}
- (NSMutableArray *)subscriptions;
- (void)openABPFeed:(NSURL*)feed;
@property (retain) id subscriptionTableView;
@property (retain) id subscriptionsArrayController;
@property (retain,getter=subscriptions) NSMutableArray* subscriptions;
and my AdBlockerPreferences.m
@implementation AdBlockerPreferences
@synthesize subscriptionTableView, subscriptions, subscriptionsArrayController;
- (id) init {
if (self = [super init]) {
// build up some sample data
subscriptions = [[NSMutableArray alloc] init];
NSString *applicationSupportFolder =
[SABApplicationSupportFolderPath stringByExpandingTildeInPath];
NSString *subscriptionsPlistPath = [applicationSupportFolder
stringByAppendingPathComponent:SABSubscriptionsPlistFullName];
NSArray* subscriptionsArray = [NSArray
arrayWithContentsOfFile:subscriptionsPlistPath];
int i = 0;
for (NSDictionary *child in subscriptionsArray)
{
NSDictionary* subscriptionsDictionary =
[subscriptionsArray objectAtIndex:i];
SubscriptionInfo* subscriptionInfo =
[[[SubscriptionInfo alloc] initWithInfoDictionary: subscriptionsDictionary]
autorelease];
[subscriptions addObject: subscriptionInfo];
i++;
}
}
return self;
}
- (void) dealloc {
[subscriptions release];
[subscriptionsArrayController release];
[super dealloc];
}
- (NSMutableArray*) subscriptions {
return subscriptions;
}
- (void)openABPFeed:(NSURL*)feed
{
/////////////////////////removed
// Create our Subscriptions plist file.
NSDictionary *output;
output = [NSDictionary dictionaryWithObjectsAndKeys:title,
@"feedNameKey",
urlString, @"feedURLKey",
defaultValue, @"feedUpdatedKey", nil];
SubscriptionInfo* subscriptionInfo = [[[SubscriptionInfo alloc]
initWithInfoDictionary: output] autorelease];
[subscriptionsArray addObject:output];
// Write the Subscriptions plist file.
[subscriptionsArray writeToFile:subscriptionsPlistPath atomically:YES];
//////////none of these are working...
//[subscriptionsArrayController addObject: subscriptionInfo];
//[[self mutableArrayValueForKey: @"subscriptions"] addObject:
subscriptionInfo];
//[[self mutableArrayValueForKey: @"subscriptions"] insertObject:
subscriptionInfo atIndex: [subscriptions count]];
//[subscriptionsArrayController insertObject: subscriptionInfo
atArrangedObjectIndex: [[subscriptionsArrayController arrangedObjects] count]];
int x = [subscriptionsArray count];
[[[[AdBlockerUpdater alloc] init] autorelease]
updateFeedWithPreferences:self atIndex:x];
}
and I call open openABPFeed: from another class, like so:
[[AdBlockerPreferences sharedInstance] openABPFeed:[request URL]];
I also tried this (just to make sure its happening on the main thread:
[[AdBlockerPreferences sharedInstance]
performSelectorOnMainThread:@selector(openABPFeed:) withObject:[request URL]
waitUntilDone:YES];
not sure what else I would need to do?
