Issue with displaying banner ads Objective-C - ios

Question

I have an issue while displaying BannerAds for 1st and every 5th row. While displaying data, first row is replaced with banner ads and every 5th row data is replaced with banner ads...How to overcome this. Following is what i have tried.TIA
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSInteger n;
n= [array count];
return n;
}
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row % 5 == 0) {
//configure ad cell
for(UIView* view in cell.contentView.subviews) {
if([view isKindOfClass:[GADBannerView class]]) {
[view removeFromSuperview];
}
}
else
{
Title.text=[NSString stringWithFormat:#"%# ",[dict objectForKey:#"Name"]];
}
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row % 5 == 0)
return 60;
else
return 153;
}

Answer 1

You need to increase the number of cells you return in numberOfRowsInSection and account for the added rows in cellForRowAt
The number of advertisements will be 1 + n/5 (The first row and then every 5th row), so the number of cells in your table will be n + n/5 + 1
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
NSInteger n;
n= [array count];
return n/5 + n + 1;
}
Now, some of the cells you need to return from cellForRowAt will be ads and you will need to account for this when accessing your data array. The index you need is the row number - the number of advertisement rows that have come before it. This is index/5 + 1 (The first row and every 5 rows).
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row % 5 == 0) {
AdCell *cell = (AdCell *)[tableView dequeueReusableCellWithIdentifier:"Ad" forIndexPath: indexPath];
...
NSLog(#"Showing an ad at row %ld",indexPath.row);
return cell;
else
{
NSInteger index = indexPath.row - indexPath.row/5 - 1;
NSDictionary *dict = myArray[index];
NormalCell *cell = (NormalCell *)[tableView dequeueReusableCellWithIdentifier:"Normal" forIndexPath: indexPath];
cell.title.text=[NSString stringWithFormat:#"%# ",dict["Name"]];
NSLog(#"Showing a normal row at row %ld (data from element %ld of array)",indexPath.row,index);
return cell;
}
}
