I'm a beginner of Swift, and I searched a lot of stuffs, but couldn't figure out and decided to post my first question ever here.
I have a table view to show tweets by using twitter fabric and I use UITableViewRowAction to present two options to users when a swipe is done on a row, "funnelOne" and "funnelTwo", to categorize their tweets by adding tags to each tweet.
In the view controller, I add two functions to make an alert and get a value of 'funnelTag' to store it to my core data.
However, I am not sure if I can correctly store the number to the core data because somehow different cell would be deleted if I push one of swipeable buttons. I know I can write a code within 'func tableView' to delete the row, but how I can get access from out of 'func tableView' to delete the row successfully??
If it can be resolved, I should be able to successfully store the value to my core data.
func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
let cell = super.tableView(tableView, cellForRowAtIndexPath: indexPath) as? CustomTableViewCell
let funnelOne = UITableViewRowAction(style: .Default, title: "funnel") {
(action, indexPath) -> Void in
funnelTag = 1 // funnelTag is Int I want to store in my Core Data
cell!.tag = funnelTag
// self.tweets.removeAtIndex(indexPath.row) - I know this is working
tableView.setEditing(false, animated: true)
}
let funnelTwo = UITableViewRowAction(style: .Default, title: "funnel") {
(action, indexPath) -> Void in
funnelTag = 2
cell!.tag = funnelTag
tableView.setEditing(false, animated: true)
// self.tweets.removeAtIndex(indexPath.row)
}
These are two functions I add. if I implement these functions, top row would be deleted even though I want to delete other row... the first function, funnelTweet() is properly working, but the second function does not seem to work correctly..
func funnelTweet(cell: CustomTableViewCell){
let index: Int = cell.tag
if SettingStore.sharedInstance.isNoAlert(){
self.submitFunnel(index, cell: cell)
} else {
self.alert = UIAlertController(title: NSLocalizedString("stock_confirm_funnel", comment: ""), message: nil, preferredStyle: .Alert)
self.alert!.addAction(UIAlertAction(title: NSLocalizedString("common_ok", comment: ""), style: .Destructive) { action in
self.submitFunnel(index, cell: cell)
})
self.alert!.addAction(UIAlertAction(title: NSLocalizedString("common_cancel", comment: ""), style: .Cancel) { action in
cell.moveToLeft()
})
self.presentViewController(self.alert!, animated: true, completion: nil)
}
}
func submitFunnel(index: Int, cell: CustomTableViewCell){
var tweet = self.tweets[index]
// store to local storage
TagStore.sharedInstance.saveData(tweet.createdAt, funnelTag: funnelTag, id: tweet.tweetID)
self.tweets.removeAtIndex(index)
self.tableView!.reloadData()
}
Thank you for your help!
In the Second function you have not initialized the index before using it.
func submitFunnel(index: Int, cell: CustomTableViewCell){
// Initialize index here before using it in the next statement.. that is give it a value, otherwise it will return nil
var tweet = self.tweets[index]
// store to local storage
TagStore.sharedInstance.saveData(tweet.createdAt, funnelTag: funnelTag, id: tweet.tweetID)
self.tweets.removeAtIndex(index)
self.tableView!.reloadData()
}
