I find this problem commonly occurs when I am placing a table view inside of a View Controller. If you're using a UITableViewController jump to 3.

These steps may help:

1: In your View Controller .h file make sure you add the following:

@interface YourViewController : UIViewController 

2: Next create an IBOutlet for your table view by ctrl + drag to your .h class. It should look like:

@property (weak, nonatomic) IBOutlet UITableView *tableView;

3: Next step is to ctrl + drag to your View Controllers icon (see image)

You need to do this twice selecting:

- delegate
- datasource

Finally, in your .m file, you should have the following method:

- (void) viewWillAppear:(BOOL)animated{
    //[self.tableView beginUpdates];
    //[self.tableView endUpdates];

    [self.tableView reloadData];
}

You can use either beginUpDates/endUpdates or reloadData, however Apple docs recommend reloadData.

Once done your table should work fine.
