TTLauncherItem: change badge immediately (or: how to refresh TTLauncherView)
- by vikingosegundo
I have a TTLauncherView with some TTLauncherItems. These show badges, representing messages from the network. I set the badges in viewWillAppear:, so if I switch to another view and then return, the correct badges are shown. But I want to update the badges as soon a message comes in.
Calling setNeedsDisplay on TTLauncherView doesn't help?
How can I refresh the TTLauncherView?
in my MessageReceiver class I do this:
TTNavigator* navigator = [TTNavigator navigator];
[(OverviewController *)[navigator viewControllerForURL:@"tt://launcher"] reloadLauncherView] ;
My TTViewController-derived OverviewController
@implementation OverviewController
- (id)init {
if (self = [super init]) {
self.title = OverviewTitle;
}
return self;
}
- (void)dealloc {
[items release];
[overView release];
[super dealloc];
}
-(void)viewDidLoad
{
[super viewDidLoad];
overView = [[TTLauncherView alloc] initWithFrame:self.view.bounds];
overView.backgroundColor = [UIColor whiteColor];
overView.delegate = self;
overView.columnCount = 4;
items = [[NSMutableArray alloc] init];
for(int i = 1; i <= NumberOfBars; ++i){
NSString *barID = [NSString stringWithFormat:NameFormat, IDPrefix, i];
TTLauncherItem *item = [[[TTLauncherItem alloc] initWithTitle:barID
image:LogoPath
URL:[NSString stringWithFormat:@"tt://item/%d", i]
canDelete:NO] autorelease];
[barItems addObject: item];
}
overView.pages = [NSArray arrayWithObject:items];
[self.view addSubview:overView];
}
-(void)viewWillAppear:(BOOL)animated
{
for(int i = 0; i <[barItems count]; i++){
TTLauncherItem *item = [items objectAtIndex:i];
NSString *barID = [NSString stringWithFormat:NameFormat, IDPrefix, i+1];
P1LOrderDispatcher *dispatcher = [OrderDispatcher sharedInstance];
P1LBarInbox *barInbox = [dispatcher.barInboxMap objectForKey:barID];
item.badgeNumber = [[barInbox ordersWithState:OrderState_New]count];
}
[super viewWillAppear:animated];
}
- (void)launcherView:(TTLauncherView*)launcher didSelectItem:(TTLauncherItem*)item
{
TTDPRINT(@"%@", item);
TTNavigator *navigator = [TTNavigator navigator];
[navigator openURLAction:[TTURLAction actionWithURLPath:item.URL]];
}
-(void)reloadLauncherView
{
[overView setNeedsDisplay];//This doesn't work
}
@end
