dequeueReusableCellWithIdentifier returns nil using storyboard static cells

I am having a heck of time with this. Using storyboard, I created a table view controller with a static cell that contains a UITextField to allow for user input. When the user is finished, I want to retrieve the contents of the text field.

Here is what I did:

  • Created a subclass of UITableViewCell named SingleLineFieldTableViewCell
  • Added IBOutlet UITextField *textField; to the subclass and declared it as a property (nonatomic, retain) and synthesized it.
  • Added IBOutlet SingleLineFieldTableViewCell *cellNamed; to the owning table view controller, and declared it as a property (nonatomic, retain) and synthesized it.

  • In storyboard, I have a table view controller with static cells. One of the cells is the custom cell, which is declared as SingleLineFieldTableViewCell and owns a UITextField. It is also assigned a cell identifier.

  • I attached referencing outlets of the table view cell and the text field to the appropriate IBOutlets listed above.

When I run, dequeueReusableCellWithIdentifier returns nil. I thought that with Xcode 4 and storyboards, dequeueReusableCellWithIdentifier, according to Converting to Storyboards Release Notes, "The dequeueReusableCellWithIdentifier: method is guaranteed to return a cell (provided that you have defined a cell with the given identifier)".

The weird part is that when I run in the Simulatior, the table appears as expected (section, cell size, etc.), except that I can't edit the custom cell.

I'm at a loss. Any help or ideas?

I know this question was a year ago, but I just went through this problem myself today.

I think the problem here is using static cells.

See the Apple docs: http://developer.apple.com/library/ios/#documentation/userexperience/conceptual/tableview_iphone/TableViewCells/TableViewCells.html

Basically the idea is that if you are using static cells then there is no need to use

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

data source method, instead just generate outlets to all your UI elements (inside the static cells) and set them directly.

If you need to use this method then you must change the table to dynamic content mode.

According to the Apple's docs (Populating a Static Table View With Data) http://developer.apple.com/library/ios/documentation/userexperience/conceptual/tableview_iphone/CreateConfigureTableView/CreateConfigureTableView.html#//apple_ref/doc/uid/TP40007451-CH6-SW31

Note: If a table view in a storyboard is static, the custom subclass of UITableViewController that contains the table view should not implement the data source protocol. Instead, the table view controller should use its viewDidLoad method to populate the table view’s data.

Thus you just need to remove all the Table View data source methods from your View Controller.


Optional:

However if your View Controller is also the data source for other dynamic Table View(s) and you still need these methods, it's possible to call only the super's corresponding data source methods for the static Table View:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Static Table View
    if (tableView == self.tableView)
        return [super numberOfSectionsInTableView:tableView];

    // Dynamic Table View
    // ...
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // Static Table View
    if (tableView == self.tableView)
        return [super tableView:tableView numberOfRowsInSection:section];

    // Dynamic Table View
    // ...
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Static Table View
    if (tableView == self.tableView)
        return [super tableView:tableView cellForRowAtIndexPath:indexPath];
