UItableView data from Plist

Question

I have a plist with thousands of Array into it.and each array contains Dictionary with 51 items in it.thats means total of some 40,000 data,I have populated into the UITableView correctly .IF I enter around 10 Array into the UITableView ..its display the rows in good view...but when I go beyond like 40 arrays ..the UITableView gets weird.you can't even understand. . .

and UITableView is below..

.

I have also tried to Exapanded rows for each section.that also not working for me ..what should I do?

EDIT code

-(void)ViewDidLoad
NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"sam" ofType:@"plist"];

//Load the file in a dictionnary
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:plistPath];

self.myData = dict;

//SORTING THE DICTIONARY    
NSArray *dicoArray = [[self.myData allKeys] sortedArrayUsingComparator:^(id firstObject, id secondObject) {
    return [((NSString *)firstObject) compare:((NSString *)secondObject) options: NSCaseInsensitiveSearch];
}];

self.mySections = dicoArray;

NSLog(@"path values%@",tableDict);


}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{



return [self.mySections count];



}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

 if ([self tableView:tableView canCollapseSection:section])
 {
    if ([expandedSections containsIndex:section])
    {

NSString *key = [self.mySections objectAtIndex:section];
NSArray *dataInSection = [[self.myData objectForKey:key] objectAtIndex:0];
return [dataInSection count];
    }
    return 1;
  }
return 1;
  }


-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSString *key = [self.mySections objectAtIndex:section];
 return [NSString stringWithFormat:@"%@", key];
}


-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
return self.mySections;
}



- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
}

// Configure the cell...

NSUInteger section = [indexPath section];
NSUInteger row = [indexPath row];



NSString *key = [self.mySections objectAtIndex:section];

NSDictionary *dataForSection = [[self.myData objectForKey:key] objectAtIndex:0];
NSArray *array=dataForSection.allKeys;

cell.textLabel.text = [[dataForSection allKeys] objectAtIndex:row];    
cell.detailTextLabel.text=[dataForSection valueForKey:[array objectAtIndex:indexPath.row]];

   return cell;     
 }

this code works fine If I take less Array say 10Array with 51 values into it...but when I take more...screen shows like this

Answer 1

I now see what the problem is. You have an index selection that is way too big.

You can remove this by removing the sectionIndexTitlesForTableView method.

If you really want this, you can format all the strings to not be bigger than a few characters like:

-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
    NSMutableArray *shorterArray = [[NSMutableArray alloc]init];
    for( NSString *sectionTitle in self.mySections ){
        NSString *shortSectionTitle;
        if( sectionTitle.length > 4 ){
            shortSectionTitle = [NSString stringWithFormat:@"%@..", [sectionTitle substringToIndex:4]];
        } else {
            shortSectionTitle = sectionTitle;
        }
        [shorterArray addObject:shortSectionTitle];
    }
    return shorterArray;
}

If you need more help, let me know

Answer 2

NSDictionary *dataForSection = [self.mySections objectAtIndex:section];
NSArray *array=dataForSection.allKeys;

cell.textLabel.text = [array objectAtIndex:row];    
cell.detailTextLabel.text=[dataForSection objectForKey:[array objectAtIndex:row]];

Answer 3

Try removing if (cell == nil) { } condition. That is declare, cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease]; outside if brackets.
