Why does my UITableView only show two rows of each section? - iphone

Question

I have a UITableView and when I build it only two rows will be displayed. Each section has more than two cells to be displayed, I am confused since they are all done the same?
#import #import "Store.h"
#import "VideoViewController.h"
#implementation Store
#synthesize listData;
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[self createTableData];
[super viewDidLoad];
}
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc that aren't in use.
}
- (void)viewDidUnload {
//self.listData = nil;
//[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
#pragma mark -
#pragma mark Table View Data Source Methods
// Customize the number of sections in the table view.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [videoSections count];
}
//Get number of rows
-(NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return [self.listData count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *StoreTableIdentifier = #"StoreTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:StoreTableIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:StoreTableIdentifier] autorelease];
}
cell.textLabel.text = [[[listData objectAtIndex:indexPath.section] objectAtIndex:indexPath.row]
objectForKey:#"name"];
//Change font and color of tableView
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.textLabel.font=[UIFont fontWithName:#"Georgia" size:16.0];
cell.textLabel.textColor = [UIColor brownColor];
return cell;

Answer 1

Replace this:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [self.listData count];
}
with:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [[self.listData objectAtIndex:section] count];
}

Answer 2

It looks like you're using only one value for the number of rows per section:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [self.listData count];
}
Does each section have the same number of rows? If not, you should be using section to grab the right number.
It's what's returned in this method (in your case, [self.listData count]) that determines how many rows to display for that section.
I'd analyze the code some more but it's pretty hard to read... :)
