I'm trying to programmatically select all rows in my tableview using the following code:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell:myTableViewCell = tableView.dequeueReusableCellWithIdentifier("Cell") as! myTableViewCell
cell.accessoryType = .None
if allJobsSelected {
let bgColorView = UIView()
bgColorView.backgroundColor = UIColor(red: 250/255, green: 182/255, blue: 17/255, alpha: 1)
cell.contentView.backgroundColor = UIColor(red: 250/255, green: 182/255, blue: 17/255, alpha: 1)
cell.selectedBackgroundView = bgColorView
cell.accessoryType = .Checkmark
cell.highlighted = false
cell.selected = true
// cell.accessoryType = .Checkmark
self.tableView.selectRowAtIndexPath(indexPath, animated: true, scrollPosition: UITableViewScrollPosition.None)
self.tableView(self.tableView, didSelectRowAtIndexPath: indexPath)
}
var job: Jobs!
job = jobs[UInt(indexPath.row)] as! Jobs
cell.reports2JobTitle.text = job.jobTitle
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
self.tableView.allowsMultipleSelection = true
if let cell:myTableViewCell = tableView.cellForRowAtIndexPath(indexPath) as? myTableViewCell {
let bgColorView = UIView()
bgColorView.backgroundColor = UIColor(red: 250/255, green: 182/255, blue: 17/255, alpha: 1)
cell.contentView.backgroundColor = UIColor(red: 250/255, green: 182/255, blue: 17/255, alpha: 1)
cell.selectedBackgroundView = bgColorView
cell.accessoryType = .Checkmark
cell.highlighted = false
self.tableView.selectRowAtIndexPath(indexPath, animated: true, scrollPosition: UITableViewScrollPosition.Bottom)
}
}
My issue is that only the rows that have been dequeued are added to my table's data model when I segue to the next viewcontroller. In order to add all the rows to my table's data model I have to manually scroll through the whole table. How can I change this so all the selected rows are added to my table's data model without having to scroll through the whole table?
What I cannot understand is that after all my rows are selected I then loop through my indexPaths as follows but not all of the indexPaths are added unless I first scroll through the entire table.
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {
if (segue.identifier == "reportsDisplay") {
let controller = segue.destinationViewController as! ReportsDisplayViewController
var selectedJob : Jobs!
if let indexPaths = tableView.indexPathsForSelectedRows {
for i in 0 ..< indexPaths.count {
let thisPath = indexPaths[i]
selectedJob = jobs[UInt(thisPath.row)] as! Jobs
let jobTitle = selectedJob.jobTitle
let id = selectedJob.identifier
jobsToReport.append(jobTitle)
jobsID.append(id)
}
}
controller.reportedJobs = jobsToReport
controller.idOfJobs = jobsID
}
}
At the time allJobsSelected becomes true, you need to call the UITableView method selectRowAtIndexPath(_:animated:scrollPosition:) for each row of your table. In my case, I attached this functionality to the right bar button item which I named Select All. Calling this from cellForRowAtIndexPath is surely not the right place.
@IBAction func doSelectAll(sender: UIBarButtonItem) {
let totalRows = tableView.numberOfRowsInSection(0)
for row in 0..<totalRows {
tableView.selectRowAtIndexPath(NSIndexPath(forRow: row, inSection: 0), animated: false, scrollPosition: UITableViewScrollPosition.None)
}
}
