Two NSMutableArrays in one UITableView with custom cells in iOS - ios

Question

In my iOS app, I am having two NSMutableArray
#implementation MyViewController {
NSMutableArray *arrOne;
NSMutableArray *arrTwo;
}
declared in my implementation file and one UITableView
#property (strong, nonatomic) IBOutlet UITableView *tableView;
declared inside MyController.h
What I want is to load both those array contents in the same table where arrOne content at first and arrTwo contants next.
Below is the way how I got number of table rows
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if ([arrOne count] > 0 && [arrTwo count] > 0) {
return [arrOne count] + [arrTwo count];
} else if ([arrTwo count] > 0) {
return [arrTwo count];
} else {
return 10;
}
}
and below is the place where I tried to create my table cells
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"myTable";
if ([arrOne count] > 0 && [arrOne count] > indexPath.row) {
UITableViewCell *defaultCell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (defaultCell == nil) {
defaultCell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
return defaultCell;
} else {
MyTableViewCell *cell = (MyTableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"MyTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
return cell;
}
}
With the above code, and assume arrOne has only one element, the tableView supposed to display first cell white and all others with my custom cell. Instead, it display, first cell white as expected and again some cells in the middle (5, 9, 13...) also in white. Cannot identify the reason yet. Any idea why?
If this is not the correct way of implementing two arrays in a single table view, what is it?

Answer 1

If arrOne contains only a single element (as you say it does) and arrTwo is empty, then you will have 10 total cells according to numberOfRowsInSection. The first cell will be a UITableViewCellStyleDefault cell, and the next 9 should be MyTableViewCell cells.
The reason you're seeing multiple UITableViewCellStyleDefault cells is because you're using the same cell identifier. Move your ID declaration inside each of the if/else statements and use a different identifier for each cell type.
if ([arrOne count] > 0 && [arrOne count] > indexPath.row) {
static NSString *defaultTableIdentifier = #"defaultReuse";
UITableViewCell *defaultCell = [tableView dequeueReusableCellWithIdentifier:defaultTableIdentifier];
if (defaultCell == nil) {
defaultCell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:defaultTableIdentifier];
}
return defaultCell;
} else {
static NSString *simpleTableIdentifier = #"myCustomCellReuse";
MyTableViewCell *cell = (MyTableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"MyTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
return cell;
}
(Also, is your Nib name different than the class name? MyTableViewCell vs MyTableCell. Because you declare a cell of the class MyTableViewCell and then load a nib named MyTableCell.)
