Xcode UICollectionView How To Disable Some Cells by indexpath - ios

Question

I have been trying to figure out how to disable cells in a collectionview by indexpath or by using the cellsforitemsatindexpath method of collectionview. I have the following code below but this only disables the last cell in the loop. I also have the following image for when I run the code in Xcode. So far only the third cell horizontal is disabled on first row at top, but I want to disable or set values to nil the first 3 cells from the top row horizontal. From the image link below, the missing '9' on the third cell indicates that value was set to nil. Any suggestions are appreciated.
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
CollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"myCollectionCell" forIndexPath:indexPath];
if (cell != nil)
{
// May not need this
NSInteger cellIndex = [myObjectsArray objectAtIndex:indexPath.row];
for (int i = 0; i < rangeNumOfCellsToDisable; i++)
{
if (indexPath.row == i)
{
// If true, code goes here
}
else
{
// If not true, code that sets stuff to nil goes here
}
}
}
return cell;
}

Hi please try this solution.
I am assuming that you want first three cells to be disabled or you can have any cells disabled..
in .h file
-#property(nonatomic,retain)NSMutableArray *disableArray;
in.m file
disableArray=[[NSMutableArray alloc]init];
[disableArray addObject:#"0"];
[disableArray addObject:#"1"];
[disableArray addObject:#"2"];
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
CollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"myCollectionCell" forIndexPath:indexPath];
if (cell != nil)
{
// May not need this
NSInteger cellIndex = [myObjectsArray objectAtIndex:indexPath.row];
if([disableArray containsObject:[NSString stringwithformat:#"%d",indexPath.row]])
{
//the row which you want to disable do whatever you want over here...Hope this helps.
}
}
return cell;
}
