EXC_BAD_ACCESS when I'm trying to delete a UITableView sections

问题

I have this code:

    // - Update the data source
    self.order.persons.removeAtIndex(index)

    // - Disable the user interaction
    self.tableView.userInteractionEnabled = false

    // - Delete the needed section from the table view
    let sectionIndexSet = NSIndexSet(index: self.order.persons.count - 1)
    self.tableView.beginUpdates()
    self.tableView.deleteSections(sectionIndexSet, withRowAnimation: .Automatic)
    self.tableView.endUpdates()

    // - Update the table view with a delay to update all the indexes 
    NSTimer.scheduledTimerWithTimeInterval(0.3, handler: {
            self.tableView.userInteractionEnabled = true
            self.tableView.reloadData()
        })

So the problem:

CASE 1: When on the visible zone of table view are another sections, not only the one that I want to delete, all works great.
CASE 2: When on the visible zone of table view is ONLY the section that I want to delete, the debugger stop at the line:

self.tableView.endUpdates()

and gives the errors :

Thread 1: EXC_BAD_ACCESS (code=1, address=0x0).

I don't understand why case 1 is working great, but case 2 not. For information, I use reusable cells.

回答1:

You are removing different data from source and in tableView

ISSUE

 // - Delete the needed section from the table view
    let sectionIndexSet = NSIndexSet(index: self.order.persons.count - 1)

FIX It should be

// - Delete the needed section from the table view
    let sectionIndexSet = NSIndexSet(index: index)
