I am creating a wall page like twitter or Facebook in which user can post on the wall it can include image and just text. So based on the content the cell's heights must change, if the post is of one line the row height must be appropriate.
I tried using UITableViewAutomaticDimensions, but its not working with my code please do help me.
import UIKit
class wallPageViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var tableOfApps : UITableView?
var appNames: [String]? = []
var apps: [wallPageModel]?
var dynamic_height : CGFloat = 150.0
var addPost : UITextField?
var readMore : UITextView?
func loadTableOfApps(){
//appNames = ["jkbajdba", "abfajfb", "akjbfkjag", "ahbfkajf" ]
let provider = wallPageProvider()
apps = provider.getApps()
let tableHeight = view.frame.size.height
tableOfApps = UITableView(frame: CGRect(x: 10, y: 60, width: 300, height: tableHeight))
tableOfApps!.delegate = self
tableOfApps!.dataSource = self
tableOfApps?.separatorStyle = UITableViewCellSeparatorStyle.none
//self.tableOfApps?.rowHeight = UITableViewAutomaticDimension
//self.tableOfApps?.estimatedRowHeight = UITableViewAutomaticDimension
print("load table of apps")
view.addSubview(tableOfApps!)
}
override func viewDidLoad() {
super.viewDidLoad()
loadTableOfApps()
loadAddPost()
tableOfApps?.estimatedRowHeight = 150.0
tableOfApps?.rowHeight = UITableViewAutomaticDimension
view.backgroundColor = UIColor(red: 232/255, green: 234/255, blue: 246/255, alpha: 1.0)
// Do any additional setup after loading the view.
}
func loadAddPost(){
addPost = UITextField(frame: CGRect(x: 10, y: 20, width: 300, height: 30))
addPost?.placeholder = "Stay safe, post a tip!"
addPost?.isUserInteractionEnabled = true
addPost?.borderStyle = UITextBorderStyle.roundedRect
addPost?.autocapitalizationType = .none
view.addSubview(addPost!)
addPost?.addTarget(self, action: #selector(writeComment), for: UIControlEvents.touchDown)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
print("app coun\(apps!.count)")
return apps!.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell : wallModelTableViewCell?
cell = tableView.dequeueReusableCell(withIdentifier: "cell") as? wallModelTableViewCell
if cell == nil {
cell = wallModelTableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "cell")
}
let app = apps![indexPath.row]//reading the array of data hence provider
//association of provider and view
//this is the processs from where view can read the data from provide
cell!.iconImageLabel!.image = app.icon
cell!.titleLabel!.text = app.title
cell?.backgroundColor = UIColor.white
cell!.commentsLabel?.image = app.comments_Label
cell?.commentsLabel?.center = CGPoint(x: tableView.frame.size.width/2, y: dynamic_height-20)
cell?.likeButtonLabel?.image = app.likeButton
cell?.likeButtonLabel?.center = CGPoint(x: (tableView.frame.size.width/2)-130, y: dynamic_height-20)
/*cell?.likeButtonLabel?.leftAnchor.constraint(equalTo: tableView.leftAnchor, constant: 50)*/
cell!.feedTextLabel!.text = app.feedText
cell?.feedTextLabel?.sizeToFit()//so that it can expand the data more than two lines
cell?.feedTextLabel?.backgroundColor = UIColor.clear
//Limiting UIlabel to 125 characters
if (cell?.feedTextLabel?.text.count)! > 125{
/*
let index = cell?.feedTextLabel?.text.index((cell?.feedTextLabel?.text.startIndex)!, offsetBy: 125)
cell?.feedTextLabel?.text = cell?.feedTextLabel?.text.substring(to: index!)
cell?.feedTextLabel?.text = cell?.feedTextLabel?.text.appending("...")*/
//cell?.feedTextLabel?.attributedText = NSAttributedString(string: "...readmore")
}
cell?.layer.cornerRadius = 6.0
cell?.isUserInteractionEnabled = false
cell?.titleLabel?.isUserInteractionEnabled = true
tableOfApps?.backgroundColor = UIColor.clear
tableOfApps?.backgroundView?.isOpaque = false
tableOfApps!.estimatedRowHeight = 150.0
tableOfApps!.rowHeight = UITableViewAutomaticDimension
print("table view cell for row")
/*let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector( self.labelAction(gesture:)))
cell?.feedTextLabel?.addGestureRecognizer(tap)
cell?.feedTextLabel?.isUserInteractionEnabled = true
tap.delegate = self as! UIGestureRecognizerDelegate*/
return cell!
}
/*@objc func labelAction(gesture: UITapGestureRecognizer){
}*/
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
print("height for row")
return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return 150.0
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Navigation
@objc func writeComment(){
let addComment = addCommentViewController()
navigationController?.pushViewController(addComment, animated: true)
}
/*
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
I want each row must have dynamic height as the content is provided by the user if the content contains 150 characters the height of the cell must be 200+ if content contains less than 125 characters the height must be as adequate to read.
