Load Array in UITableView Cell - ios

Question

I want to make paging swipe left and right using UIScrollView after view detailController.
First, main.m:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
OZDetailViewController *detailViewController = [[OZDetailViewController alloc] initWithNibName:#"OZDetailViewController" bundle:nil];
detailViewController.arrDetailNews = [_arrNews objectAtIndex:indexPath.row];
[self.navigationController pushViewController:detailViewController animated:YES];
OZDetailViewController *arrNewsAll = [[OZDetailViewController alloc] initWithNibName:#"OZDetailViewController" bundle:nil];
arrNewsAll.allNewsArray = _arrNews;
[self.navigationController pushViewController:arrNewsAll animated:YES];
}
When I selected content in tableviewcell, arrDetailNews can loaded in method viewDidLoad() and cellForRowAtIndexPath(). But arrNewsAll cannot loaded in method cellForRowAtIndexPath().
This is my detailViewController.h:
#property (nonatomic, copy) NSArray *allNewsArray;
And detailViewCOntroller.m:
#synthesize allNewsArray;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.separatorColor = [UIColor clearColor];
NSLog(#"dataArray: %#", allNewsArray);
}
- (int)numberINSectionsInTableView: (UITableView *)tableView
{
return 1;
}
- (int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 4;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"dataArrayCell: %#", allNewsArray);
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"New Cell"];
}
if(indexPath.row != self.arrDetailNews.count-1){
UIImageView *line = [[UIImageView alloc] initWithFrame:CGRectMake(0, 44, 320, 2)];
line.backgroundColor = [UIColor whiteColor];
[cell addSubview:line];
}
tableView.allowsSelection = NO;
cell.textLabel.text = [NSString stringWithFormat:#"%u", indexPath.row];
if (indexPath.row==0) {
cell.textLabel.text = #"1st";
}
if (indexPath.row==1) {
cell.textLabel.text = #"2nd";
}
if (indexPath.row==2) {
cell.textLabel.text = #"3rd";
}
return cell;
}
If allNewsArray can loaded in cellForRowAtIndexPath() I can continue next step for paging with UIScrollView. Note, numberOfRowsInSection I set to 4 because I need 4 rows (custom view).

Assuming you setup your delegate & dataSource outlets correctly from xib/storyboard, you still need to specify the number of rows per section (or number of sections).
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return allNewsArray.count;
}
Alternatively, the method for number of sections is:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView;
