Re: [iPhone-AppDev-Auditors] assignment 4, requirement 10: How to repopulate Recently Viewed Table Cell, when User views a new photo in Top Place Table?

Does your setter for recentlyViewPhotos do a 'reloadData' on the tableView?

Yes I did. The NSUserDefaults does get updated. The problem is the "Recently Viewed Table" does NOT get repopulated when User click on the "Recently Viewed Tab".

I should mention that "- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section" does NOT get called when User click on the "Recently Viewed Tab". 

For Reference: Following is the code to storing Recently Viewed Photo to NSUserDefaults:

 //Store Photo to NSUserDefaults, RecentlyViewedPhotoViewController will use it to display

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    NSMutableArray *photos = [[defaults objectForKey:RECENTILYVIEWEDPHOTOS_KEY] mutableCopy];

    if(!photos) photos = [NSMutableArray array];

    if ([photos indexOfObject:self.photo] == NSNotFound) {

        [photos addObject:self.photo];

        [defaults setObject:photos forKey:RECENTILYVIEWEDPHOTOS_KEY];

        if(![defaults synchronize]) NSLog(@"failed");   

    }

Hi zak, are you doing 'synchronize' after you update your NSUserDefaults object?

Currently, I am setting my Recently Viewed Table Data Source in "-

(void)viewWillAppear:(BOOL)animated", which work for first time when

the application is launched. But it does NOT work when user views a

new photo at Top Place Tab.

I am getting the NSUserDefaults' Recently Viewed Photo List at

viewWillAppear. And I update NSUserDefaults at Top Place Tab.

- (void)viewWillAppear:(BOOL)animated

{

  [super viewWillAppear:animated];

  self.recentlyViewedPhotos = [[NSUserDefaults standardUserDefaults]

objectForKey:RECENTILYVIEWEDPHOTOS_KEY];

}
