In UITableView,cellForRowAtIndexPath ignore the first few rows - ios

Question

I've used sqlite in my project and I get ten elements in _mChats (array) successfully. The numberOfRowsInSection method returns 10 but cellForRowAtIndexPath ignores the first few rows and in simulator other elements all display on the same cell,why?
And if I use sections instead of rows to display data,everything becomes normal.
This is my code:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [_mChats count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
VChat *cell = [VChat vChatWithTableView:tableView];
cell.mChat = _mChats[indexPath.section];
return cell;
}

Answer 1

I think its because of this
cell.mChat = _mChats[indexPath.section];
Try this instead
cell.mChat = _mChats[indexPath.row];
This is because Indexpath is a property that has two values inside it,
Eg. IndexPath [section,row] meaning indexpath of something is section number 1, row number 5.
Hope this helps you understand.

This is how your cellForRowAtIndexPath should look like:
- (UITableViewCell *)tableView:(UITableView *)iTableView cellForRowAtIndexPath:(NSIndexPath *)iIndexPath {
NSString *cellIdentifier = #"myCell";
UITableViewCell *cell = (UITableViewCell *)[iTableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellIdentifier];
}
cell.mChat = _mChats[indexPath.row];
return cell;
}

Answer 3

- (UITableViewCell *)tableView:(UITableView *)iTableView cellForRowAtIndexPath:(NSIndexPath *)iIndexPath
{
VChat *cell = (VChat *)[tableViewdequeueReusableCellWithIdentifier:#"CellIdentifier"];
NSArray *nib = [[NSBundle mainBundle]loadNibNamed:#"VChat" owner:self options:nil];
if (cell==nil)
{
cell = nib[0];
}
cell.mChat = _mChats[indexPath.row];
return cell;
}

The three delegate method must be implement you have wrote have something wrong. As #Abhinav said the method return cell have some thing wrong.
As the code you showed will create a new cell when a new cell present in the screen. I think the first few rows just because the cell has't be reused.
There is another thing I want to say, if you are using storyboard to build the tableview this method should seems like:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// The identifier in storyboard you setted.
static NSString *cellName = #"theCell";
Cell *cell = [tableView dequeueReusableCellWithIdentifier:cellName];
if (dataSource_[indexPath.row]) {
// This method will bind data to view
[cell fillDataWithDict:dataSource_[indexPath.row]];
}
return cell;
}
