i tried to add a Symbolic Breakpoint for -[NSObject(NSObject) doesNotRecognizeSelector:] but that didnt show which piece of code sent that selector

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITableViewCellScrollView _tableView]: unrecognized selector sent to instance 0x8e46570'

Answer 1

by applying some coloring to the cell, i saw that when i swipe the cell from the accessory view app crashes
a work around is to set the accessoryType to UITableViewCellAccessoryNone in tableView:cellForRowAtIndexPath:
cell.accessoryType = UITableViewCellAccessoryNone;

Hey ~ I've just solved this bug by removing the codes below in my custom UItableview Cell, but I don't know if it may help you
self.contentView.userInteractionEnabled = NO;
In my case, disable the userinteractionEnabled for cell content view will cause exactly the same crash when I trying to swipe left or right in a custom UItableView in iOS7,
and it shall be fixed by removing it

Considering the error you're getting and these lines:
0x01ac90ee _CF_forwarding_prep_0 + 14
0x00785f7a -[UITableViewCellScrollView gestureRecognizerShouldBegin:] + 203
it appears that you've somehow set an instance of UITableViewCellScrollView as the delegate of a gesture recognizer. Since UITableViewCellScrollView probably doesn't implement the UIGestureRecognizerDelegate protocol, you eventually get an unrecognized selector exception.
Examine the gesture recognizer in each of your table cells closely and check the identity of their delegates.
