Actually, I copied that behavior from an iOS developer who show me a demo in an ipad & a new version iphone.

The behavior was like,
In Ipad,
I can only have a single item selected for deletion, (i.e, when a swipeleft, happens other item, one that having selected class losses its selected class.

In Iphone,
On swipeleft, the item with the content goes to little more left, where the delete indicator is not seen and not rotated.

I am new to iOS!
