accessorytype of uitableview doesn't appear

I allowed selection in edit mode using

allowsSelectionDuringEditi开发者_运维知识库ng = YES ;

but at selection I want to add accessory the cell the problem is that the accessory doesn't appear

I change it in cellForRowAtIndexPath

if (self.editing) {

    NSLog(@" Editing mode  ");

     cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;


}
else {
    // cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator ; 
}

I made sure that it enter the if statement because it display Editing mode

any suggestion

use

editingAccessoryType

instead of

accessoryType
