iOS User editable .plist for UITableView

troop231 said:

My app uses a .plist as it's table data source, but I want to add the ability for my users to hide and unhide certain cells that don't interest them.

I know that I can put the table into editing mode and have the user swipe to delete cells, but that isn't what I'm looking for because the user may want to restore those deleted cells at a later time, or if they mistakenly deleted a cell.

I'm looking for the checkmark type of cell marking/unmarking so the user can create a "favorites" list if you will. When the user is done being in the table "edit" mode, he/she will tap done, and the app will save what cells are to be hidden from being displayed in the table view into a settings .plist.

How could I go about doing this?

Thank you for any help offered.

By using the .hidden property for each cell?

I tried this, but my table view doesn't compensate for the empty space left by the hidden cells.

Is there a way to compensate by using

Code:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

Code:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
    if (cell == nil) cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
    
    NSArray *documentsPath = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *PlistPath = [NSString stringWithFormat:@"%@/%@", [documentsPath objectAtIndex:0],@"Table.plist"];
    
    NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:PlistPath];
    
    NSInteger row = [indexPath row];
    
    // Set up the cell...
	NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row];
    
    if(row == 4 && ([[dict objectForKey:@"4"]isEqualToString:@"0"])){
        cell.hidden = YES;
    }
    if(row == 7 && ([[dict objectForKey:@"7"]isEqualToString:@"0"])){
        cell.hidden = YES;
    }
    
    else {
    
    tableView.separatorColor = [UIColor clearColor];
	cell.textLabel.text = [dictionary objectForKey:@"Title"];
    cell.textLabel.textColor = [UIColor whiteColor];
    cell.textLabel.highlightedTextColor = [UIColor colorWithRed:0.071 green:0.204 blue:0.565 alpha:1];
}
return cell;

So if I understand correctly, I need to parse my app's table data before displaying it based upon the user's settings in the .plist? Do you know how I could do this? I'm having a hard time trying to grasp it, because my app gets it's data like this:

Code:

NSArray *tempArray = [[NSArray alloc] init];
		self.tableDataSource = tempArray;
		
		AppDelegate *AppDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
		self.tableDataSource = [AppDelegate.data objectForKey:@"Rows"];

Should I use NSPredicate to search the user's settings plist and then use that to display the filtered user's table data?

AppDelegate *AppDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

// First fetch all objects
NSMutableArray *allObjects = [NSMutableArray arrayWithArray:[AppDelegate.data objectForKey:@"Rows"]];

// Create a predicate
// shouldBeHidden is the name of the boolean property
NSPredicate *aPredicate = [NSPredicate predicateWithFormat:@"shouldBeHidden == 0"];

// Filter the array
[allObjects filterUsingPredicate:aPredicate];

// Set it as the data source
self.tableDataSource = allObjects;

Thank you for that!

How would I set the predicate to search for the boolean keys in a different .plist? The user's settings are stored in a different plist than the table's source.

Sorry, I probably didn't explain it right.

I have solved it now though however by using the code you created. I can't believe I overlooked it.

Thank you again sir!
