cellForRowAtIndexPath does not fire. What am i missing? - objective-c

Question

I am trying to achieve this:
but i get this:
I have a view cotroller with a view table on it
This is the interface:
#interface LoginViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>
#property (weak, nonatomic) IBOutlet UITableView *tblCredentials;
#end
This is the implementation:
#interface LoginViewController ()
#end
#implementation LoginViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
}
-(void)viewWillAppear:(BOOL)animated
{
self.tblCredentials.delegate=self;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 2;
}
// Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier:
// Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
UITextField *textField = [[UITextField alloc] init];
textField.enablesReturnKeyAutomatically = YES;
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.autocapitalizationType = UITextAutocapitalizationTypeNone;
CGRect cellBounds = cell.bounds;
CGFloat textFieldBorder = 10.f;
CGRect aRect = CGRectMake(textFieldBorder, 9.f, CGRectGetWidth(cellBounds)-(2*textFieldBorder), 31.f );
textField.frame = aRect;
if(indexPath.row==0)
{
textField.placeholder = #"Username";
textField.returnKeyType = UIReturnKeyNext;
textField.autocapitalizationType = UITextAutocapitalizationTypeWords;
}
else
{
textField.placeholder = #"Password";
textField.returnKeyType = UIReturnKeyDone;
textField.secureTextEntry = YES;
}
[cell.contentView addSubview:textField];
return cell;
}
#end
I put a breakpoint on the in the cellForRowAtIndexPath and it doesn't stop there, so those text fields don't get rendered.
What am I missing?
PS: Is this a bad approach to achieve the goal? (those two grouped text fields)
LE: I am using stroyboard with no xib files

Answer 1

In viewDidLoad, you must set the delegate and call [self.tblCredentials reloadData] in order for the table view to actually "load its data"

Answer 2

You need to create a Custom Table View cell. have a look at this github link.

Answer 3

You're setting the delegate of the table view, but not the datasource, which is where the number of rows etc. comes from.
You're also setting the delegate a bit late in the cycle. Since this is in a xib, why not set the delegate and datasource in the xib instead of in code? If you declare that your view controller conforms to the delegate and data source properties in the header, you will be able to make the connection in IB. If you insist on setting it in code, it should be in viewDidLoad.

Answer 4

Set delegate and dataSource in -viewDidLoad and put [self.tblCredentials reloadData] in -viewWillAppear:.
- (void)viewDidLoad
{
[super viewDidLoad];
self.tblCredentials.delegate=self;
self.tblCredentials.dataSource=self;
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated]; // BTW, it's better to call super's -viewWillAppear: here, according to apple's documentation.
[self.tblCredentials reloadData];
}
