Question

In xcode 6 while deleting cell in my to do list i randomly get an error
"exc_bad_access code=exc_i386_gpflt"
i have got a two views - on second i enter items in array "toDoList"
In first i show all item from "toDoList" and have an option to delete when, code of first page in this:
import UIKit
var toDoList: [String] = []
class FirstViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
//var cell = UITableViewCell()
#IBOutlet weak var itemList: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
return toDoList.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
var cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
cell.textLabel.text = toDoList[indexPath.row]
return cell
}
override func viewWillAppear(animated: Bool) {
if var storedItems: AnyObject = NSUserDefaults.standardUserDefaults().objectForKey("items"){
toDoList = []
for var i = 0; i < storedItems.count; ++i{
toDoList.append(storedItems[i] as NSString)
}
}
itemList.reloadData()
}
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath){
if editingStyle == UITableViewCellEditingStyle.Delete{
toDoList.removeAtIndex(indexPath.row)
let saveData = toDoList
NSUserDefaults.standardUserDefaults().setObject(saveData, forKey: "items")
NSUserDefaults.standardUserDefaults().synchronize()
itemList.reloadData()
}
}
}

Answer 1

What's causing your error is
itemList.reloadData()
in your function
func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath)
So to fix your problem, remove that line and then add this line after toDoList.removeAtIndex(indexPath.row):
tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.None)
What this method does is: Deletes the rows specified by an array of index paths, with an option to animate the deletion. (from Xcode Quick Help)
