ios swift uitableview sections with different tabledata - ios

Question

I have a list of data coming in from json. With this list I would like to load it into a tableview but within two seperate sections called Featured and All. Trying to figure out how to get my "Featured" section not to load the same amount of rows as the "All" section. All section is good but Featured section shows Featured list plus 16 empty rows. Any ideas on how I get rid of these extra rows in the Featured section?
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
if(section == 0)
{
return "Featured"
}
return "All"
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
var sections: Int = 2
return sections
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var count: Int = tableData.count
println("tabledata \(count)")
return count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//let session = NSURLSession.sharedSession()
tableView.estimatedRowHeight = 44.0
tableView.rowHeight = UITableViewAutomaticDimension
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "Cell")
let entry : NSMutableDictionary = self.tableData[indexPath.row] as! NSMutableDictionary
var featured = entry["Business_IsFeatured"] as? String
if ((featured == "1") && (indexPath.section == 0))
{
var busName = entry["Business_Name"] as? String
var points = entry["Member_Points"] as? String
var imageName = entry["Business_Image"] as? String
var imgURL: NSURL = NSURL(string: "http://www.example.com/images/\(imageName!)")!
let request: NSURLRequest = NSURLRequest(URL: imgURL)
NSURLConnection.sendAsynchronousRequest(
request, queue: NSOperationQueue.mainQueue(),
completionHandler: {(response: NSURLResponse!,data: NSData!,error: NSError!) -> Void in
if error == nil {
cell.textLabel!.text = busName
cell.textLabel!.numberOfLines = 0
cell.detailTextLabel!.text = "Points: \(points!)"
cell.imageView!.image = UIImage(data: data)
}
})
}
else
{
if((featured == "0") && (indexPath.section == 1))
{
var busName = entry["Business_Name"] as? String
var points = entry["Member_Points"] as? String
var imageName = entry["Business_Image"] as? String
var imgURL = NSURL(string: "http://www.example.com/images/\(imageName!)")
cell.textLabel!.text = busName
cell.textLabel!.numberOfLines = 0
cell.detailTextLabel!.text = "Points: \(points!)"
cell.imageView!.hnk_setImageFromURL(imgURL!, format: Format<UIImage>(name: "original"))
}
}
return cell
}

Answer 1

Your implementation of UITableViewDataSource's
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
method needs to supply the number of rows you intend for each section to contain. Your code returns the same number of rows regardless of the section, which sounds wrong based on how you describe what you want to do. You need to calculate and return the number of featured items for your Featured section, rather than the size of your entire dataset.

Answer 2

The "tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int" function is here for this. Depending of the section, you return the numbers of rows into this section
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if(section==0){
var count: Int = tableData.count
println("tabledata \(count)")
return count
}else{
return theOtherData.count
}
}

#tomsoft and #ScorpioCurse I was able to get the featured section to load up the correct data by making two seperate arrays for the data. Before I was trying to return count which swift wasnt liking. After changing it to return a separate array tableFeatData.count else return tableData.count I got it working. I also had to add a second dictionary. Code below. I may still need to clean up some of this code.
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//let session = NSURLSession.sharedSession()
tableView.estimatedRowHeight = 44.0
tableView.rowHeight = UITableViewAutomaticDimension
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "Cell")
let entry : NSMutableDictionary = self.tableData[indexPath.row] as! NSMutableDictionary
var featured = entry["Business_IsFeatured"] as? String
if ((featured != "1") && (indexPath.section == 0))
{
let featentry: NSMutableDictionary = self.tableFeatData[indexPath.row] as! NSMutableDictionary
var busName = featentry["Business_Name"] as? String
var points = featentry["Member_Points"] as? String
var imageName = featentry["Business_Image"] as? String
var imgURL: NSURL = NSURL(string: "http://www.example.com/images/\(imageName!)")!
let request: NSURLRequest = NSURLRequest(URL: imgURL)
NSURLConnection.sendAsynchronousRequest(
request, queue: NSOperationQueue.mainQueue(),
completionHandler: {(response: NSURLResponse!,data: NSData!,error: NSError!) -> Void in
if error == nil {
cell.textLabel!.text = busName
cell.textLabel!.numberOfLines = 0
cell.detailTextLabel!.text = "Points: \(points!)"
cell.imageView!.image = UIImage(data: data)
}
})
}
else
{
var busName = entry["Business_Name"] as? String
var points = entry["Member_Points"] as? String
var imageName = entry["Business_Image"] as? String
var imgURL = NSURL(string: "http://www.example.com/images/\(imageName!)")
cell.textLabel!.text = busName
cell.textLabel!.numberOfLines = 0
cell.detailTextLabel!.text = "Points: \(points!)"
cell.imageView!.hnk_setImageFromURL(imgURL!, format: Format<UIImage>(name: "original"))
}
return cell
}
