Hi,
I'm seeing some weird things reloading the data in my
IKImageBrowserView in my GC collected, Leopard app. Basically
depending on how I change the contents of my "filteredItems"
NSMutableArray I get a different loading behaviour.
If I refresh the contents like this the IKImageBrowserView seems to
ignore the imageUID and reload everything again:
[self.filteredItems setArray: self.prefilteredItems];
[imageBrowserView reloadData];
while if I do the much more elaborat following it seems to reuse
everything properly and doesn't do the weird reloading of everything:
NSMutableArray *array = [NSMutableArray arrayWithCapacity:
[self.filteredItems count]];
for(id obj in self.filteredItems){
if(![self.prefilteredItems containsObject: obj])[array
addObject: obj];
}
[self.filteredItems removeObjectsInArray: array];
for(id obj in self.prefilteredItems){
if(![self.filteredItems containsObject: obj])[self.filteredItems
addObject: obj];
}
Any idea why this is? How come the imagebrowserview seems to monitor
my mutablearray?
Also, any tips on how to solve the issue, or a workaround? The above
one is (too) slow.
I have done everything accoding to the ImageKit demo, including
implementing imageUID in my model object, and implementing the
delegates as follows:
- (NSInteger)numberOfItemsInImageFlow:(IKImageFlowView*)view{
return [filteredItems count];
}
- (id)imageFlow:(IKImageFlowView *) view itemAtIndex:(NSInteger) index{
return [filteredItems objectAtIndex:index];
}
Thanks,
Alex
