Reuse custom TableViewCell - ios

Question

I have a viewController that contains a programmatically created tableView.
#property (strong, nonatomic) UITableView *numbersTableView;
//...
self.numbersTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, -100, self.view.frame.size.width-20, 50)];
self.numbersTableView.delegate = self;
self.numbersTableView.dataSource = self;
self.numbersTableView.tag = 1;
self.numbersTableView.layer.cornerRadius = 5;
[self.numbersTableView setBounces:false];
[self.numbersTableView setHidden:true];
[self.numbersTableView registerClass:[AZGCountryCell class] forCellReuseIdentifier:#"NumbersTableViewCell"];
[self.view addSubview:self.numbersTableView];
For the prototype cell I want to use a prototype that I created somewhere else in another viewController and I designed It in storyboard.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
if (tableView.tag == 1) { //tableView == self.numbersTableView
NSString *cellID = #"NumbersTableViewCell";
AZGCountryCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) {
cell = [[AZGCountryCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
cell.countryName.text = self.numbersArray[indexPath.row].number;
cell.flagImageView.image = [UIImage imageNamed:self.numbersArray[indexPath.row].country];
return cell;
}
}
And my custom cell contains one UIImageView and one UILabel but when I run the code the cells are empty and I can see the UIImageView and UILabel are nil!
#import <UIKit/UIKit.h>
#interface AZGCountryCell : UITableViewCell
#property (strong, nonatomic) IBOutlet UIImageView *flagImageView;
#property (strong, nonatomic) IBOutlet UILabel *countryName;
#property (strong, nonatomic) IBOutlet UILabel *countryCode;
#end
#import "AZGCountryCell.h"
#implementation AZGCountryCell
#synthesize flagImageView;
#synthesize countryName;
- (void)awakeFromNib {
[super awakeFromNib];
self.flagImageView.layer.cornerRadius = self.flagImageView.frame.size.width/2;
self.flagImageView.layer.masksToBounds = YES;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:selected animated:animated];
}
#end
Then what should I do to have properly filled cells in my numbersTableView?

Answer 1

Unfortunately you can't reuse a table cell you've defined in a table view in a storyboard in your separate class.
In order for you to be able to share your cell between the different views, you'll have to extract the view to a separate nib and register that nib go be used on both tables.
Alternatively you can implement the cell's UI in code in the table view cell subclass.

You getting empty cell because custom tableview cell not registered, use
[self.numbersTableView registerNib:[UINib nibWithNibName:#"AZGCountryCell" bundle:nil] forCellReuseIdentifier:#"NumbersTableViewCell"];
instead of
[self.numbersTableView registerClass:[AZGCountryCell class] forCellReuseIdentifier:#"NumbersTableViewCell"];
