Doesn't work UITableViewCell's method - ios

Question

When I do simple HelloWorld app I have problem with
[self.tableView insertRowsAtIndexPaths:#[indexPath]withRowAnimation:UITableViewRowAnimationAutomatic]
,this method doesn't work... and i don't know why? pliz help
Code:
- (void)viewDidLoad
{
int i = 0;
[super viewDidLoad];
while (i < 10 ) {
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView insertRowsAtIndexPaths:#[indexPath]withRowAnimation:UITableViewRowAnimationAutomatic];
i++;
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.textLabel.text = #"HelloWorld";
return cell;
}
App should create 10 cells with Label #"HelloWorld"

Answer 1

You're going about this the wrong way. If you want 10 cells you shouldn't be trying to add them one at a time, you should just return 10 in numberOfRowsInSection, e.x:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 10;
}
Additionally, nothing will show up in the cells because you have call alloc/init on the cells in cellForRowAtIndexPath. Modify your code to do so like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = #"HelloWorld";
return cell;
}
