indentationLevelForRowAtIndexPath not indenting custom cell

Question

I have overridden the tableView:indentationLevelForRowAtIndexPath method in my UITableViewController derived class as follows:

Similar to the accepted answer, this is how it can be done in iOS 8 while still using layoutSubviews with AutoLayout instead.

With _viewConstraints as an NSMutableArray ivar and _imageView as the closest view to the left side of the cell's content view.

- (void)layoutSubviews
{
    float indentPoints = indentationLevel * [self indentationWidth];

    [self removeConstraints:_viewConstraints];
    [_viewConstraints removeAllObjects];

    NSDictionary *views = NSDictionaryOfVariableBindings(imageView);
    [_viewConstraints addObjectsFromArray:[NSLayoutConstraint constraintsWithVisualFormat:[NSString stringWithFormat:@"H:|-(%f@1000)-[_imageView]", indentPoints] options:0 metrics:nil views:views]];
    [self addConstraints:_viewConstraints];
}

If you have AutoLayout constraints defining everything else in the view then this should push the whole view over the desired indentation amount.

NOTE if using Nib: You should define the constraint (in this case between _imageView and its super view) as >= some number (in my case it was 20). Then the original constraint, and the one being added/removed in layoutSubviews don't conflict with each other.

You should also consider calling the following in awakeFromNib

[_imageView setTranslatesAutoresizingMaskIntoConstraints:NO]

This is so the old "springs and struts" don't get in the way of the constraints you are adding.
