How can I change the amount of indentation on my custom UITableViewCell while editing?

Question

I have made a custom UITableViewCell, and done it properly (adding everything to contentView, and overriding layoutSubviews so my subviews are rela

You've got to override layoutSubviews and do something like the following. And don't forget to set the indentation level to something greater than 0 :) For custom cells the indentation level is not applied by default.

To avoid indentation for the single swipe to delete gesture you'll have to do a but more work. There is a state which reflects the editing state of the cell.It is not public but can be accessed with - (void)willTransitionToState:(UITableViewCellStateMask)aState, so storing it in a property does the work for layoutViews.

Apple's documentation for willTransitionToState:

Note that when the user swipes a cell to delete it, the cell transitions to the state identified by the UITableViewCellStateShowingDeleteConfirmationMask constant but the UITableViewCellStateShowingEditControlMask is not set.

header file

int state;

...

@property (nonatomic) int state;

...

cell implementation

@synthesize state;

- (void)layoutSubviews
{
    [super layoutSubviews];

    self.contentView.frame = CGRectMake(0,                                          
                                        self.contentView.frame.origin.y,
                                        self.contentView.frame.size.width, 
                                        self.contentView.frame.size.height);

    if (self.editing
        && ((state & UITableViewCellStateShowingEditControlMask)
        && !(state & UITableViewCellStateShowingDeleteConfirmationMask)) || 
            ((state & UITableViewCellStateShowingEditControlMask)
         && (state & UITableViewCellStateShowingDeleteConfirmationMask))) 
    {
        float indentPoints = self.indentationLevel * self.indentationWidth;

        self.contentView.frame = CGRectMake(indentPoints,
                                            self.contentView.frame.origin.y,
                                            self.contentView.frame.size.width - indentPoints, 
                                            self.contentView.frame.size.height);    
    }
}

- (void)willTransitionToState:(UITableViewCellStateMask)aState
{
    [super willTransitionToState:aState];
    self.state = aState;
}
