didSelectRowAtIndexPath called after long press - ios

I have a uitableview right below a uitextfield that populates similar strings in a uitableview cell.
The items get populated. However the didSelectRowAtIndexPath gets called after long press
My UITableView (is embedded in UIScrollView)
- didSelectRowAtIndexPath: only being called after long press on custom cell
My view hierarchy:
UIScrollView (outerscroll)
Some other views and buttons
UITexfield
UITableView (tableView)
My Code
class MyViewController: BaseViewController , UITextFieldDelegate , UITableViewDelegate , UITableViewDataSource , UIGestureRecognizerDelegate {
#IBOutlet weak var autocompleteTableView: UITableView!
var pastUrls = ["Men", "Women", "Cats", "Dogs", "Children","aaaaaaaaa","aaaaaaaaaaaaaaaaaaa","aaaaaaaaa","a","aa","aaa"]
var autocompleteUrls = [String]()
#IBOutlet weak var image_view_seacrh_ifsc: UIImageView!
#IBOutlet weak var scrollView: UIScrollView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
self.scrollView.panGestureRecognizer.delaysTouchesBegan = true
autocompleteTableView.delegate = self
autocompleteTableView.dataSource = self
autocompleteTableView.scrollEnabled = true
autocompleteTableView.alwaysBounceVertical = false
autocompleteTableView.allowsSelection = true
autocompleteTableView.allowsSelectionDuringEditing = true
autocompleteTableView.hidden = true
super.hideKeyboard()
super.showNavigationBarBackButton()
let gesture_search_ifsc = UITapGestureRecognizer(target: self, action: "action_Search_Ifsc:")
gesture_search_ifsc.delegate = self
gesture_search_ifsc.numberOfTapsRequired = 1
image_view_seacrh_ifsc.userInteractionEnabled = true
image_view_seacrh_ifsc.addGestureRecognizer(gesture_search_ifsc)
}
func searchAutocompleteEntriesWithSubstring(substring: String)
{
autocompleteUrls.removeAll(keepCapacity: false)
for curString in pastUrls
{
var myString:NSString! = curString as NSString
var substringRange :NSRange! = myString.rangeOfString(substring)
if (substringRange.location == 0)
{
autocompleteUrls.append(curString)
}
}
autocompleteTableView.reloadData()
//autocompleteTableView.hidden = false
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return autocompleteUrls.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell: AutoBankCell = tableView.dequeueReusableCellWithIdentifier("AutoBankCell") as! AutoBankCell
cell.label.text = self.autocompleteUrls[indexPath.row]
//cell.lbl.text = self.autocompleteUrls[indexPath.row]
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let selectedCell : UITableViewCell = tableView.cellForRowAtIndexPath(indexPath)!
self.bank_name.text = self.autocompleteUrls[indexPath.row]
self.autocompleteTableView.scrollEnabled = true
self.autocompleteTableView.hidden = true
}
}
My UItableView gets populated and works properly when not embedded in UIScrollView.

Try to add uiview in your scroll view and add every elements in that uiview like your tableView,textfield,views and buttons etc.
So, that view works as container view.
Make sure that you are setting proper constraints if you are using autolayout.
Second thing remove unnecessary gesture recognizer implicitly which is not required.
Tableview have scroll enable by default so not need to set it true again. (it's not affect your issue btw!!)
So remove unnecessary configuration and make proper setup and your issue will be solved i think.

UiView fixed on top of UiTableViewController

I need to put an UIView fixed on top of UITableViewController (like a header). I've tried this:
override func scrollViewDidScroll (scrollView: UIScrollView) {
var fixedFrame: CGRect = self.uiTopView.frame;
fixedFrame.origin.y = scrollView.contentOffset.y;
self.uiTopView.frame = fixedFrame;
}
But it does not work and I don't know why. Someone have any idea?
This can not be done, one way to accomplish this is to add the UITableViewController insideUIContainerView
So the structure will be as follows:
ViewController1 contains aUIContainerView this container view has embedded segue
to your tableViewController.
Then you can add the view to the ViewController1.
Why do you actually use UITableViewController instead of UIViewController with a tableView inside?
Maybe you should add your header view first then add you tableview depending on the header's frame.
for example: `import UIKit
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
var fixedLabel : UILabel!
var tableView : UITableView!
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
self.tableView.frame = CGRectMake(0, self.fixedLabel.frame.maxY, self.view.frame.width, self.view.frame.height-70)
self.fixedLabel.frame = CGRectMake(0,0,self.view.bounds.width,70)
}
override func viewDidLoad() {
super.viewDidLoad()
self.fixedLabel = UILabel()
self.fixedLabel.backgroundColor = UIColor.blueColor()
self.fixedLabel.text = "This is a fixedLabel"
self.fixedLabel.textAlignment = .Center
self.tableView = UITableView()
self.tableView.delegate = self
self.tableView.dataSource = self
self.view.addSubview(fixedLabel)
self.view.addSubview(tableView)
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell : UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("cell")
if cell == nil {
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "cell")
}
cell?.textLabel?.text = "Your text"
return cell!
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
}
`

No call to my didSelectRowAtIndexPath function

I'm trying to create an app that displays some data on labels on the top of a screen, and then the lower half or so is a table which will allow selection of an item in the table to pop up another segue for editing a value. I'm struggling though to get the didSelectRowAtIndexPath to be called when an item on the list is selected by the user. I've put the code for the View controller below.
I've searched quite a bit and haven't found anything so far that explains the issue I'm seeing.
I think I've connected everything up correctly as far as delegates and datasource, and I'm not using any gesture captures so it's not those. Does anyone have any ideas?
I've attached screen grabs of the view controller connections and attributes inspector settings as well.
Connections screengrab
Attributes screengrab
import UIKit
class TemperatureViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var CurrentTemp: UILabel!
#IBOutlet weak var HeaterStatus: UILabel!
#IBOutlet weak var ChillerStatus: UILabel!
#IBOutlet weak var TempTableView: UITableView!
var settings = [TemperatureSettings] ()
var HeaterTemp:Float = 0.0
var ChillerTemp:Float = 0.0
var ThresholdTemp:Float = 0.0
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.loadTempSettings()
TempTableView.delegate = self
TempTableView.dataSource = self
TempTableView.allowsSelection = true
TempTableView.editing = false
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
self.loadTempSettings()
}
func loadTempSettings() {
let TempSetting1 = TemperatureSettings(name: "Heater On at", CurrentSetting: HeaterTemp)!
let TempSetting2 = TemperatureSettings(name: "Chiller On at", CurrentSetting: ChillerTemp)!
let TempSetting3 = TemperatureSettings(name: "Threshold", CurrentSetting: ThresholdTemp)!
settings = [TempSetting1, TempSetting2, TempSetting3]
TempTableView.reloadData()
//refreshControl?.endRefreshing()
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return settings.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
// Stop spoof separators after the table entries for blank entries
tableView.tableFooterView = UIView(frame: CGRect.zeroRect)
// Turn off the separator for each cell.
tableView.separatorStyle = UITableViewCellSeparatorStyle.None
let cellIdentifier = "TemperatureSettingsTableViewCell"
let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as! TemperatureSettingsTableViewCell
let setting = settings[indexPath.row]
cell.SettingNameLabel.text = setting.name
cell.SettingCurrentLabel.text = String(format: "%.1f C", setting.CurrentSetting)
cell.SettingCurrentLabel.textAlignment = .Left
// Configure the cell...
//useTimer = true
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("Setting Row \(indexPath.row) clicked")
performSegueWithIdentifier("Settings", sender: self)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
This works for me:
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("works");
}
Add override before func maybe?

Swift - UITableView inside UIViewController, UITableView functions are not called

I inserted a tableview inside a UIViewController. But my code is not working. When I checked I found that none of the tableview functions are not called.
class CustomViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var authorArticlesTableView: UITableView!
var authorid: Int!
var authorname: String!
var articles: [JSON]? = []
func loadArticles(){
let url = "http:here.com/" + String(authorid) + "/"
println(url)
Alamofire.request(.GET, url).responseJSON { (Request, response, json, error) -> Void in
if (json != nil){
var jsonObj = JSON(json!)
if let data = jsonObj["articles"].arrayValue as [JSON]?{
self.articles = data
self.authorArticlesTableView.reloadData()
}
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
self.loadArticles()
println("viewDidLoad")
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
println("numberOfRowsInSection")
return self.articles?.count ?? 0
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("CustomCell") as! CustomTableViewCell
cell.articles = self.articles?[indexPath.row]
println("cellForRowAtIndexPath")
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
performSegueWithIdentifier("WebSegue", sender: indexPath)
tableView.deselectRowAtIndexPath(indexPath, animated: true)
}
Any solution for this?
Thanks,
You have to set your view controller as a table view delegate/datasource:
add to the end of the viewDidLoad:
authorArticlesTableView.delegate = self
authorArticlesTableView.dataSource = self
Set table delegate and dataSource :
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
Sometimes, if you forget to drap and drop UITableViewCell to UITableView. XCode don't understand TableView has Cell.
By default, when you drap and drop UITableView into UIViewController. I see UITableView has Cell. But you need to drap and drop UITableViewCell into UITableView also.
It is work with me.
Makes sense to do it in your
#IBOutlet weak var authorArticlesTableView: UITableView!
so it will become
#IBOutlet weak var authorArticlesTableView: UITableView! {
didSet {
authorArticlesTableView.delegate = self;
authorArticlesTableView.dataSource = self;
}
}

dynamic tableview inside custom tableviewcell

I'm trying to create a tableview with custom cells that each one holds a tableview.
I want to show the inner tableview just when it have some data (most of the time it's empty). I've managed to display the cells but can't display their tableview if it's populated with data.
The problem also is that the cell height needs to be dynamic according to the amount of data to display.
The cell code:
class feedViewCell: UITableViewCell , UITableViewDataSource , UITableViewDelegate {
#IBOutlet var feedCellImage: UIImageView!
#IBOutlet var feedCellUserName: UILabel!
#IBOutlet var feedCellDate: UILabel!
#IBOutlet var feedCellComments: UILabel!
#IBOutlet var cardView: UIView!
#IBOutlet var repliesTableView: UITableView!
var repliesArray:[Reply] = []
#IBAction func addComment(sender: AnyObject) {
}
override func awakeFromNib() {
super.awakeFromNib()
var nib = UINib(nibName: "feedComment", bundle: nil)
repliesTableView.registerNib(nib, forCellReuseIdentifier: "commentCell")
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
override func layoutSubviews() {
cardSetup()
}
func cardSetup() {
cardView.layer.masksToBounds = false
cardView.layer.cornerRadius = 5
cardView.layer.shadowOffset = CGSizeMake(-0.2, 0.2)
cardView.layer.shadowRadius = 1
cardView.layer.shadowOpacity = 0.2
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return repliesArray.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = repliesTableView.dequeueReusableCellWithIdentifier("commentCell", forIndexPath: indexPath) as CommentFeedCell
cell.commentCellUserName.text = repliesArray[indexPath.row].userName
return cell
}
}
And the Main controller code:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var comment = comments[indexPath.row]
let cell: feedViewCell = tableView.dequeueReusableCellWithIdentifier("feedCell", forIndexPath: indexPath) as feedViewCell
cell.feedCellUserName.text = comment.userName
cell.feedCellImage.backgroundColor = UIColor.redColor()
cell.feedCellComments.text = "\(comment.replies.count) COMMENTS"
cell.repliesArray = comment.replies
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "dd-MM-yyy"
cell.feedCellDate.text = dateFormatter.stringFromDate(NSDate())
if cell.repliesArray.count > 0 {
cell.repliesTableView.rowHeight = UITableViewAutomaticDimension
}
cell.repliesTableView.reloadData()
return cell
}
How to show the inner tableview only in cells which have comments (and hiding the tableview in cells with 0 comments)?
Call super in layoutSubviews and let us know what happens.
override func layoutSubviews() {
super.layoutSubviews()
cardSetup()
}

UITableView only updating on scroll up, not down

I have a UITableView that updates when I scroll up, but it does not update when I scroll down. Furthermore, when it does update it occasionally seems to "skip" a cell and update the next one.
There are 6 total cells that should populate
I've created the UITableView in the storyboard, set my constraints for both the hashLabel and the creditLabel in storyboard
Here is the image of the initial TableView:
And upon scrolling up, when updated properly:
...and when scrolling up "misses" a cell:
and of course, the class:
class HashtagController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var model:ModelData!
var currentCell: UITableViewCell!
#IBOutlet var hashtagTableView: UITableView!
let basicCellIdentifier = "CustomCells"
override func viewDidLoad() {
super.viewDidLoad()
model = (self.tabBarController as CaptionTabBarController).model
hashtagTableView.delegate = self
hashtagTableView.dataSource = self
self.navigationController?.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "CherrySwash-Regular", size: 25)!, NSForegroundColorAttributeName: UIColor(red:27.0/255, green: 145.0/255, blue: 114.0/255, alpha: 1.0)]
configureTableView()
hashtagTableView.reloadData()
}
func configureTableView() {
hashtagTableView.rowHeight = UITableViewAutomaticDimension
hashtagTableView.estimatedRowHeight = 160.0
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
//deselectAllRows()
hashtagTableView.reloadData()
}
override func viewDidAppear(animated: Bool) {
hashtagTableView.reloadData()
}
func deselectAllRows() {
if let selectedRows = hashtagTableView.indexPathsForSelectedRows() as? [NSIndexPath] {
for indexPath in selectedRows {
hashtagTableView.deselectRowAtIndexPath(indexPath, animated: false)
}
}
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return model.quoteItems.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
return customCellAtIndexPath(indexPath)
}
func customCellAtIndexPath(indexPath:NSIndexPath) -> CustomCells {
var cell = hashtagTableView.dequeueReusableCellWithIdentifier(basicCellIdentifier) as CustomCells
setTitleForCell(cell, indexPath: indexPath)
setSubtitleForCell(cell, indexPath: indexPath)
return cell
}
func setTitleForCell(cell:CustomCells, indexPath:NSIndexPath) {
let item = Array(Array(model.quoteItems.values)[indexPath.row])[0] as? String
cell.hashLabel.text = item
}
func setSubtitleForCell(cell:CustomCells, indexPath:NSIndexPath) {
let item = Array(model.quoteItems.keys)[indexPath.row]
cell.creditLabel.text = item
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
/*currentCell = tableView.cellForRowAtIndexPath(indexPath) as UITableViewCell!
var currentLabel = currentCell.textLabel?.text
var currentAuthor = currentCell.detailTextLabel?.text
model.quote = currentLabel!
model.author = currentAuthor!*/
}
}
class CustomCells: UITableViewCell {
#IBOutlet var hashLabel: UILabel!
#IBOutlet var creditLabel: UILabel!
}
As it turns out, the issue had to do with my estimatedRowHeight. In this case the row height was too large and it was effecting the way the table cells were being constructed.
So in the end I changed hashtagTableView.estimatedRowHeight = 160.0 to hashtagTableView.estimatedRowHeight = 80.0 and everything worked just fine.
