I am using Swift 2 with XCode 7.2 in my extension. I am rendering UITableView with Cells that have image and label in it the problem is that the image are hidden ! Idn't know why! can anyone help me please
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel!.textColor = UIColor.whiteColor()
let query = PFQuery(className:"Recipe")
query.orderByDescending("createdAt")
query.findObjectsInBackgroundWithBlock {
(objects: [PFObject]?, error: NSError?) -> Void in
if error == nil {
print("Success retrieved \(objects!.count) scores.")
if let objects = objects {
for object in objects {
let a:String = object.objectForKey("title") as! String
self.contentString.append(a)
}
}
let cellImg : UIImageView = UIImageView(frame: CGRectMake(5, 5, 50, 50))
cellImg.backgroundColor=UIColor.whiteColor()
cellImg.image = UIImage(named: "jj.png")
// cell.addSubview(cellImg)
cell.imageView!.image=cellImg.image
cell.textLabel!.text = self.contentString[indexPath.row]
}}
return cell
}

How to Set data to second tableview in same Class in swift.I am using two tables in the the same controller one for dropdown and another for listing. I am unable to set data to second table(listing) in class
as else part is not called in cellForRowAtIndexPath. Thanks in Advance
import UIKit
class PunchClockVC: UIViewController , UITableViewDataSource, UITableViewDelegate{
var appdel = UIApplication.sharedApplication().delegate as! AppDelegate
#IBOutlet weak var dropdownTable: UITableView!
#IBOutlet weak var mainTable: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
self.mainTable.registerClass(PunchClockCustomCell.self, forCellReuseIdentifier: "PunchClockCustomCell")
self.dropdownTable.registerClass(UITableViewCell.self, forCellReuseIdentifier: "dropdowncell")
self.dropdownTable.hidden = true
}
#IBAction func textFieldTapped(sender: AnyObject) {
if self.dropdownTable.hidden == true {
self.dropdownTable.hidden = false
}
else{
self.dropdownTable.hidden = false
}
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == dropdownTable {
return jobArrayID.count
}
return 8
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView == self.dropdownTable {
let cell = tableView.dequeueReusableCellWithIdentifier("dropdowncell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel?.text = (jobArrayID[indexPath.row] as! String) + "-" + (jobArrayName[indexPath.row] as! String)
return cell
}
else {
let cell1 = tableView.dequeueReusableCellWithIdentifier("PunchClockCustomCell", forIndexPath: indexPath) as! PunchClockCustomCell
if indexPath.row == 0
{
cell1.jobcell?.font = UIFont(name: "MuseoSlab-500", size: 25.0)

It's quite simple You need to set it only with cellForRowAtIndexPath method but the main thing to do is you need to code like below
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
if tableView == firstTbaleView
//outlet given to first tableView
{
let cell = tableView.dequeueReusableCellWithReuseIdentifier("cell1", forIndexPath: indexPath) as! cust1TableViewCell
cell.imgView.image = images[indexPath.row]
cell.filtLabel.text = self.filtersCount[indexPath.row]
return cell
}}else {
let cell2 = tableView.dequeueReusableCellWithReuseIdentifier("cell2", forIndexPath: indexPath) as! cust2TableViewCell
cell2.imgview.image = UIImage(named: colPhotos[indexPath.row])
cell2.labl.text = colNames[indexPath.row]
// cell2.layer.borderColor = UIColor.blueColor().CGColor
// cell2.layer.borderWidth = 2.0
return cell2
}
and that's it you can ask me for any help..
Lets make this a little safer:
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == self.dropdownTable {
return jobArray.count
}
else if tableView == self.mainTable {
return = 5
}
//Default return 0. This way if references are broken or change, you won't crash
return 0
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView == self.dropdownTable {
let cell = tableView.dequeueReusableCellWithIdentifier("dropdowncell", forIndexPath: indexPath) as! UITableViewCell
//configure your cell
return cell
}
else if tableView == self.mainTable {
let cell = tableView.dequeueReusableCellWithIdentifier("PunchClockCustomCell", forIndexPath: indexPath) as! PunchClockCustomCell
//configure your cell
return cell
}
//Shouln't ever reach here, but again, if we refactor somewhere then we'll see an error show up before here.
return UITableViewCell()
}
I created a custom tableviewcell with a photo and two labels. I queried some data from parse and the cells are suppposed to update the image and labels to reflect the query, however only the first viewcell works correctly. The image and labels work, however the second viewcell only displays the image correctly, the uilabels do not display any text. I've looked over the code multiple times and cant seem to figure out what i am doing wrong...
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("mySpotCell")/*, forIndexPath: indexPath)*/as? CustomTableViewCell
// cell = PFTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
if let value = mySpots[indexPath.row]["location"] {
let location = CLLocation(latitude: (value.latitude)!, longitude: (value.longitude)!)
self.geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemark, error) -> Void in
if error != nil {
print("error: \(error!.localizedDescription)")
}
if let pm: CLPlacemark = placemark![indexPath.row] {
// var pm = placemark![indexPath.row] as CLPlacemark
//self.parkingSpotAddress.text = pm.thoroughfare
// self.navigationController?.navigationBar.topItem?.title = pm.thoroughfare
//cell!.textLabel?.text = "\(pm.subThoroughfare!) \(pm.thoroughfare!)"
cell?.subtitleLabel.text = "\(pm.subThoroughfare!) \(pm.thoroughfare!)"
cell?.titleLabel.text = pm.description
print(cell?.subtitleLabel.text)
print(cell?.titleLabel.text)
}
})
if let parkingSpotImageFile: PFFile = mySpots[indexPath.row]["firstPhoto"] as! PFFile! {
parkingSpotImageFile.getDataInBackgroundWithBlock({ (imageData, error) -> Void in
if error == nil {
cell?.spotImageView.image = UIImage(data: imageData!)
// self.imageIndicator.stopAnimating()
// self.imageIndicator.hidden = true
}
})
}
I think you can check your func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int first. The value you return inside is the number of row it will show and load in tableview.
And my cellForRowAtIndex is like this, I think yours should be alright also. Just check the number of row in section.
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell:MenuTableViewCell = tbvMenu.dequeueReusableCellWithIdentifier("identifier") as! MenuTableViewCell
let temp:String = MenuArr[indexPath.row] as! String
cell.mainMenuTitle.text = temp
return cell
}
can anyone tell me what's wrong with my code i always get the same data repeated in all cells
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel!.textColor = UIColor.whiteColor()
let query = PFQuery(className:"book")
query.findObjectsInBackgroundWithBlock {
(objects: [PFObject]?, error: NSError?) -> Void in
var contentString:String = String()
if error == nil {
print("Success retrieved \(objects!.count) scores.")
if let objects = objects {
for object in objects {
let a:String = object.objectForKey("title") as! String
contentString = a
}
}
cell.textLabel!.text = contentString
}}
return cell
}
It will be better to query all your data into viewDidLoad() or any life cycle you would like.
var contentString = [String]() //<-- use an array of string instead of a string variable
override func viewDidLoad()
{
super.viewDidLoad()
let query = PFQuery(className:"book"){ query.findObjectsInBackgroundWithBlock {
(objects: [PFObject]?, error: NSError?) -> Void in
if error == nil {
print("Success retrieved \(objects!.count) scores.")
if let objects = objects {
for object in objects
{
let value = object["title"] as! String
self.contentString.append(value) //<-- save the query value to your array
}
self.tableView.reloadData() //<--- then you reload your UI
}
}}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel!.textColor = UIColor.whiteColor()
cell.textLabel!.text = self.contentString[indexPath.row] //<-- then assign the value into your cell
return cell
}
content inside your loop should be like this.
let a:String = object.objectForKey("title") as! String
contentString += a
and i noticed your block calls for same query always. can you tell me whats the different there
query.findObjectsInBackgroundWithBlock {
(objects: [PFObject]?, error: NSError?) -> Void in
var contentString:String = String()
if error == nil {
print("Success retrieved \(objects!.count) scores.")
if let objects = objects {
for object in objects {
let a:String = object.objectForKey("title") as! String
contentString = a
}
}
cell.textLabel!.text = contentString
}}
The query in cellForRowAtIndex is trouble. Imagine, every time a cell comes into view, the code asks for every book from the server.
Put the query outside the datasource method (viewWillAppear, for example). When the query is complete, initialize an array property with the results (e.g. self.bookObjects = objects).
Then in cellForRowAtIndex...
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel!.textColor = UIColor.whiteColor()
// this is the important idea...
let object = self.bookObjects[indexPath.row]
let a:String = object.objectForKey("title") as! String
cell.textLabel!.text = a
return cell
I want to Save the First or the Last Image from the UICollectionView and Save it in the UITabelView Cell as UIImage.I try it with the first indexPath if indexPath == 0 catch the UIImage and then save it in CoreData as NSData but it doest works. Have anyone an idea how can i make that or gives another way to Display the UIImage in the UITableViewCell? Thanks for Help.
Here was the code from the UICollectionViewCell:
override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier("BookPicCell", forIndexPath: indexPath) as! BookPicCell
let cellcore = picture[indexPath.row]
cell.BookImage.image = UIImage(contentsOfFile: cellcore.foto!)
if indexPath.row == 0 {
let firstpic = cell.BookImage.image
let firstcell = UIImagePNGRepresentation(firstpic!)
let firstimag = NSEntityDescription.insertNewObjectForEntityForName("Book", inManagedObjectContext: self.mgdContext) as! Book
firstimag.firstimage = firstcell!
}
do {
try self.mgdContext.save()
} catch {
print("Error")
}
return cell
}
Here was the Code from the UITableViewCell:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let Cell = BookTableView.dequeueReusableCellWithIdentifier("BookCell", forIndexPath: indexPath) as! BookCell
let books = book[indexPath.row]
Cell.BookTitle.text = books.title
let picturecount = books.picture!.count
Cell.BookImageCount.text = "\(picturecount) Picture"
let firstpicture = books.firstimage!
Cell.BookImage.image = UIImage(data: firstpicture)
return Cell
}
The program launched and displayed the images from parse with no error, when i ran it again it crashed. My question is if it is because the images aren't scaled to the correct size of the custom cell.
here is the error: the item width must be less than the width of the UICollectionView minus the section insets left and right values.
fatal error: Array index out of range
here is my function:
// Get Brands
func getBrand () {
// Create PFQuery
var query:PFQuery = PFQuery(className: "BrandInfo")
// Call findobjects
query.findObjectsInBackgroundWithBlock {
(objects:[AnyObject]?, error: NSError?) -> Void in
// refresh array
self.brands = [String]()
self.pics = [UIImage]()
// loop through array
for brandObject in objects! {
// get PFObjects
let brandName:String? = (brandObject as! PFObject)["Name"] as? String
if brandName != nil {
self.brands.append(brandName!)
}
let brandPicture = brandObject["Image"] as! PFFile
brandPicture.getDataInBackgroundWithBlock({ (imageData:NSData?, error:NSError?) -> Void in
if(error == nil){
let brandImage = UIImage(data: imageData!)
self.pics.append(brandImage)
println(self.pics.count)
}
})
}
// Refresh CollectionView
self.collectionView.reloadData()
}
}
// Setting up collection view
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return self.brands.count
}
func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell:collectionViewCell = self.collectionView.dequeueReusableCellWithReuseIdentifier("Cell", forIndexPath: indexPath) as! collectionViewCell
// Get elements
let picToDisplay:UIImage? = pics[indexPath.row] // here is where the warning occurs
let dataToDisplay:String = brands[indexPath.row]
let imageView:UIImageView? = cell.viewWithTag(2) as? UIImageView
// Set labels
cell.brandImage.image = picToDisplay
cell.brandLabel.text = dataToDisplay
return cell
Check if you are getting same count for brands and pics array.
In your case you should append array only if you both the brandImage and BrandName.So that your pics and brands array count will be same.
