Iwat 的代码对我不起作用.但这有效.

Iwat's code doesn't work for me. But this works.

- (void)willTransitionToState:(UITableViewCellStateMask)state {

    [super willTransitionToState:state];

    if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask) {

        for (UIView *subview in self.subviews) {

            if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {             

                subview.hidden = YES;
                subview.alpha = 0.0;
            }
        }
    }
}

- (void)didTransitionToState:(UITableViewCellStateMask)state {

    [super didTransitionToState:state];

    if (state == UITableViewCellStateShowingDeleteConfirmationMask || state == UITableViewCellStateDefaultMask) {
        for (UIView *subview in self.subviews) {

            if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {

                UIView *deleteButtonView = (UIView *)[subview.subviews objectAtIndex:0];
                CGRect f = deleteButtonView.frame;
                f.origin.x -= 20;
                deleteButtonView.frame = f;

                subview.hidden = NO;

                [UIView beginAnimations:@"anim" context:nil];
                subview.alpha = 1.0;
                [UIView commitAnimations];
            }
        }
    }
}
