Animating custom-drawn UITableViewCell when entering edit mode

Thanks to Craig's answer which pointed me in the right direction, I have a solution for this. I reverted my commit which moved the text position based on the editing mode and replaced it with a new solution that sets the entire content view to the correct position any time layoutSubviews is called, which results in an automatic animation when switching to and from edit mode:

- (void)layoutSubviews
{
    CGRect b = [self bounds];
    b.size.height -= 1; // leave room for the separator line
    b.size.width += 30; // allow extra width to slide for editing
    b.origin.x -= (self.editing) ? 0 : 30; // start 30px left unless editing
    [contentView setFrame:b];
    [super layoutSubviews];
}

By doing it this way I was able to remove the setFrame: override found in ABTableViewCell.m because its former logic plus my additions are now found in layoutSubviews.

I set a light grey background on the cells to verify a custom background works properly without allowing us to see behind it as it moves back and forth and it seems to work great.

Thanks again to Craig and anyone else who has looked into this.

How are you moving the text around currently? Or more specifically, in which UITableViewCell method are you performing the move?

From my experience, overriding the layoutSubviews method and setting the frame here will automatically be wrapped in an animation.

Eg:

- (void)layoutSubviews {
    if (self.editing) {
        [titleLabel setFrame:CGRectMake(62, 6, 170, 24)];
    }
    else {
        [titleLabel setFrame:CGRectMake(30, 6, 200, 24)];
    }
    [super layoutSubviews];
}

For fully control on editing in your custom cell, you should override willTransitionToState method in your UITableViewCell subclass and check state mask

- (void)willTransitionToState:(UITableViewCellStateMask)state
{
    NSString *logStr = @"Invoked";
    if ((state & UITableViewCellStateShowingEditControlMask)
        != 0) {
        // you need to move the controls in left
        logStr = [NSString stringWithFormat:@"%@
                  %@",logStr,@"UITableViewCellStateShowingEditControlMask"];
    }
    if ((state & UITableViewCellStateShowingDeleteConfirmationMask)
        != 0) {
        // you need to hide the controls for the delete button
        logStr = [NSString stringWithFormat:@"%@
                  %@",logStr,@"UITableViewCellStateShowingDeleteConfirmationMask"];
    }
    NSLog(@"%@",logStr);
    [super willTransitionToState:state];
}

also you can override layoutSubviews

- (void)layoutSubviews {
    // default place for label
    CGRect alarmTimeRect = CGRectMake(37, 7, 75, 30);
    if (self.editing && !self.showingDeleteConfirmation) {
        // move rect in left
        alarmTimeRect = CGRectMake(77, 7, 75, 30);
    }
    [alarmTimeLabel setFrame:alarmTimeRect];
    [super layoutSubviews];
}

To handle swiping as well: (self.editing && !self.showingDeleteConfirmation)
