CellForRowAtIndexPath is not called sometimes after calling numberOfRowsInSection when calling reloadData

I have a simple application where I have a table view and depending on the callback with the array, I reload the table data using the method reloadData. Initially, during the first 5-10 times of loading, this kind of table works without problems. After playing with the application, sometimes I noticed that the table view is empty due to the reason why cellForRowAtIndexPathit is not called by the infrastructure. I checked that datasourceboth are delegateset correctly, and numberOfRowsInSectionreturns a real positive number. When I see an empty table view, I see this empty view several times until I exit the application. I do not receive any errors or warnings in the console. I tried tuning the array, but to no avail.

Here is the code:

- (void)notifyArrayLoaded:(NSArray *)arr {
    NSUInteger capacity = [arr count];
    _tbDataArray = [[NSMutableArray alloc] initWithCapacity:capacity];

    // _tbDataArray is filled with the data from arr

    // Reload the table data
    [_tableView reloadData]; 
}

Any hint would be much appreciated.

Thanks in advance. Sumit
