Question

I want to show UITableviewCell from nib file. And also want to add dynamic label on it. But the label is override it self.
Please provide me any method where I can call UITableviewCell from nib and also add dynamic label.

{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
UINib *nib = [UINib nibWithNibName:#"ItemCell" bundle:nil];
[[self tblView] registerNib:nib forCellReuseIdentifier:#"ItemCell"];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 4;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 150.0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
ItemCell *cell = [tableView dequeueReusableCellWithIdentifier:#"ItemCell"];
for (int i=0; i<4; i++) {
UILabel *lbl=[[UILabel alloc] initWithFrame:CGRectMake(0.0, 20.0*i, 150.0, 20.0)];
lbl.text=#"This is custom cell.";
[cell.contentView addSubview:lbl];
}
return cell;
}

Answer 1

Use this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UILabel *lbl;
ItemCell *cell = (ItemCell *)[tableView dequeueReusableCellWithIdentifier:#"ItemCell"];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"ItemCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
lbl=[[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 150.0, 60.0)];
lbl.tag = indexpath.row;
[cell.contentView addSubview:lbl];
}
lbl = (UIlabel*) [cell.contentView viewWithTag:indexpath.row];
lbl.text=#"This is custom cell.";
return cell;
}

Try this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
ItemCell *cell = [tableView dequeueReusableCellWithIdentifier:#"ItemCell"];
UILabel* label = (UILabel*)[cell.containtView viewWithTag:indexPath.row];
if(!label) {
UILabel *lbl=[[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 150.0, 60.0)];
lbl.text=#"This is custom cell.";
lbl.tag = indexPath.row
[cell.contentView addSubview:lbl];
}
label.text = #"your text";
return cell;
}
