dequeued UITableViewCell has incorrect layout until scroll (using autolayout)

I have a custom UITableViewCell subclass which has had autolayout constraints applied to it in Interface Builder. The cell contains multiple views, including a UITextField.

Relevantly, the size of the UITextField is constrained such that there is default horizontal spacing between it and the next view.

  • UIBarButtonItem: How can I find its frame?
  • 'The 'Pods' target has transitive dependencies that include static binaries' when installing GCM
  • Is it possible to use Dropbox, Google Drive, Skydrive, etc. as a server space?
  • UITableView reloadData automatically calls resignFirstResponder
  • AVAssetWriter unknown error
  • The cell is instantiated like follows:

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
        static NSString *CellIdentifier = @"ProgressCell";
        ProgressCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier
        cell.textField.text = @"Some string that is different for each cell";
        return cell;

    When the cell first appears, the UITextField overruns the correct frame, and appears behind the UIView to its right. However, when I scroll the cell off screen, pause, and then scroll back, the text is truncated correctly.

    An example is shown below (at the second edit).

    I have tried calling [cell setNeedsLayout] and [cell setNeedsDisplay] for the cell in cellForRowAtIndexPath, as well as performing them after a delay. Neither is effective.

    What is scrolling off screen doing that is causing the cell to appear correctly, and how can I either replicate this or fix the underlying issue?



    [self.tableView reloadData];
    [self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationAutomatic];

    in order to reload the cell, appears to cause the layout to appear correctly first time.

    However, it now breaks (occasionally) on scrolling (ie, when scrolling back up, the layout constraints are now not applied correctly).

    Calling [cell setNeedsLayout] in cellForRowAtIndexPath appears not to fix this issue.


    The top cell, as shown here, appeared correctly (as the bottom cell does) until I scrolled down the screen. It since disappeared.

    This reflects the problem as of the first edit – it’s the second rendering that is the problem (makes me think that it might have something to do with reusing the cell?)

    If you name a property on a UITableViewCell subclass textLabel or defaultTextLabel, then IB will ignore the constraints you have specified and override them with default ones, with no warnings issued.

    This is the case even on cells designed in IB with the Custom style, which have no visible textLabel or detailTextLabel properties.

    In accordance to this multiple lines UILabel GitHub issue, this is a lingering iOS bug.

    I found that in iOS 9+, this situation mostly occurs in editing mode, with much unpredictability.

    The following workaround only partially works: it requires redrawing the UITableView twice, and still does not cover all scenarios.

    override func viewDidLoad() {


    • Using UITextView is a great alternative to multiple line UILabel, without the bug. UITextView does not exhibit any of the IULabel other oddities either, like alignment errors or flickering.
    • There is also an alternative solution on SO-25947146, which did not work for me but is worth mentioning.
    • Seems to occur prominently when self.tableView.editing is true
    • Using low values for tableView.estimatedRowHeight reduces the occurrence
