Empty custom prototype cell

问题


I'm new in iPhone development and have problem with prototype cell. In my storyboard, I have navigation controller. I pushed it with view controller (as main window), it has a button, when I click it I open tableView controller with custom prototype cell

- (IBAction)searchClick:(id)sender {
CNCarTableController *car = [[CNCarTableController alloc]init];
[self.navigationController pushViewController:car animated:TRUE];

}

But when it opens it has empty rows

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:     ( NSIndexPath *)indexPath
 {
  static NSString *CellIdentifier = @"TransportCell";
  CNTransportCell *cell = [tableView       dequeueReusableCellWithIdentifier:CellIdentifier];

// Configure the cell...
if(cell == nil){
   cell = [[CNTransportCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
//cell.textLabel.text = @"bmv";

cell.name = (UILabel*) [cell viewWithTag:100];
[cell.name setText:@"a text"];
cell.number.text = @"number";
cell.car.text = @"car";
return cell;

}

But if will use cell.textLabel.text = @"bmv"; all works ok. But for custom cell way with tags or cell.lbl.text don't work. What is wrong there? Can it be a nuance of navigation controller with view controller?

Custom cell code:

  @interface CNTransportCell : UITableViewCell

  @property (nonatomic,weak) IBOutlet UILabel *name;
  @property (nonatomic,weak) IBOutlet UILabel *number;
  @property (nonatomic,weak) IBOutlet UILabel *car;

@end

   @implementation CNTransportCell
   @synthesize name;
   @synthesize number;
   @synthesize car;

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
  {
   self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
  if (self) {
    // Initialization code
  }
   return self;
 }
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
 {
   [super setSelected:selected animated:animated];

// Configure the view for the selected state
  }

@end

回答1:


you have done small mistake there. Your custom cell class is "CNPlayerCell" & you are allocating new cells from "CNTransportCell" class.

One more thing, have you assigned custom class to your prototype cell in IB? (In identity inspector)
