POUITableViewCells scroll horizontally using auto layout when changing to portrait mode

Body
copied!<p>I am creating a screen that is primarily a UITableView with cells that have differing controls and layouts. I had the tableview working great until I switched to portrait mode where it allowed the tableview cells to scroll horizontally. The cells should never scroll horizontally; only vertically. When I navigate to the screen and I'm already in portrait mode it works fine, even going to landscape and back to portrait.</p> <p>Some things to note are that I'm using and iPad, storyboards, auto layout, and the UITableViewCell is custom and does not have a nib (though it does the same thing when I tried using a nib). All controls and layout constraints are added programmatically. I am using a custom view controller with a view inside of it. Inside of the view I have the tableview and a toolbar. If I remove the view so that the tableview is directly under the custom view controller it works fine, but then I can't have the toolbar.</p> <p>Here is the test code I am using to troubleshoot the problem:</p> <pre><code>// Remove all existing subviews for(UIView *subView in self.contentView.subviews) { [subView removeFromSuperview]; } UILabel *testLabel = [[UILabel alloc] init]; testLabel.text = @"Test"; [testLabel setTranslatesAutoresizingMaskIntoConstraints:NO]; self.contentView addSubview:testLabel]; NSDictionary *viewsDictionary = NSDictionaryOfVariableBindings(testLabel); NSString *format = [NSString stringWithFormat:@"V:|-[testLabel]-|"]; NSArray *constraintsArray = [NSLayoutConstraint constraintsWithVisualFormat:format options:nil metrics:nil views:viewsDictionary]; //[self.contentView addConstraints:constraintsArray]; </code></pre> <p>The scrolling works as intended until I uncomment the line to add the constraints. This code is in a method of my custom cell and gets called every time a cell is dequeued. I've tried adding the contraints individually, without using the visual format, with no luck. I have also done some research and found the code that removes the contraints from the cell and adds them to the contentView, but that hasn't helped either.</p> <p>What do I need to do to keep the cells from scrolling horizontally when changing from landscape to portrait mode?</p> <p>MORE INFO: After some more debugging I found that the table view's content size is not shrinking horizontally. The width is staying at 1024.</p>
