TableView showing wrong data after segue - ios

Question

This is a project is a simple car's dictionary, I am using core data, from a .csv file uploaded from a server.
When I select the word in the first tableview trigger a second page to read the definition in another tableview, there is the problem is always showing incorrect word and definition.

Answer 1

You are ignoring the section number in the index path you get from tableView.indexPathForSelectedRow. For a sectioned table, you need to translate a section/row combination into a data reference.
A standard way of doing that is with an array of arrays (e.g. dictionaryItems:[[Dictionary]]). That way, you can get an array of items by using the index path section on the outer array and the specific item by using the index path row on the array the section reference returns.
--- UPDATE with methods that need code changes in DictionaryTableViewController
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// Assume a single section after a search
return (searchController.active) ? 1 : sectionTitles.count
}
// Create a standard way to get a Dictionary from an index path
func itemForIndexPath(indexPath: NSIndexPath) -> Dictionary? {
var result: Dictionary? = nil
if searchController.active {
result = searchResults[indexPath.row]
} else {
let wordKey = sectionTitles[indexPath.section]
if let items = cockpitDict[wordKey] {
result = items[indexPath.row]
}
}
return result
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! DictionaryTableViewCell
if let dictionary = itemForIndexPath(indexPath) {
cell.wordLabel.text = dictionary.word
cell.definitionSmallLabel.text = dictionary.definition
} else {
print("Cell error with path \(indexPath)")
}
return cell
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "showDictionaryDetail" {
if let indexPath = tableView.indexPathForSelectedRow {
let destinationController = segue.destinationViewController as! DictionaryDetailViewController
if let dictionary = itemForIndexPath(indexPath) {
destinationController.dictionary = dictionary
} else {
print("Segue error with path \(indexPath)")
}
searchController.active = false
}
}
}

I checked your code and think the trouble is with destinationController.dictionary = (searchController.active) ? searchResults[indexPath.row] : dictionaryItems[indexPath.row]
you should get dictionary like this (as you did in cellForRowAtIndexPath):
let dictionary = (searchController.active) ? searchResults[indexPath.row]: dictionaryItems[indexPath.row]
let wordKey = sectionTitles[indexPath.section]
let items = cockpitDict[wordKey]
Now item will be the dictionary to pass to detail view.
I got this idea, when I saw you are populating your data in table view very efficiently.
