Can anyone tell me how to change the text size in a tableView so that the text in the screenshot below fits within the width of the screen:
The current tableView code is:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
cell.textLabel!.text = self.dataArray[indexPath.row]
cell.imageView!.image = UIImage(named: "20x20_empty-round-radiobutton-choice-ui")
return cell
}
Thanks in advance!
Try the following code:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
cell.textLabel!.text = self.dataArray[indexPath.row]
cell.textLabel.font = UIFont(name: cell.textLabel.font.fontName, size:15) // Change the font size as per your requirement
cell.imageView!.image = UIImage(named: "20x20_empty-round-radiobutton-choice-ui")
return cell
}
Set autoshrink minimum fontScale. If your text is long enough to exceed the actual Label Frame,then your font will be shrinked upto minimum font scale you provide in storyboard or xib.

how to add a right detail to a cell that already have left detail and subtitle. and how to give a textLabel to the right detail?
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let monster = monsters[indexPath.row]
cell.textLabel?.text = monster.name
cell.detailTextLabel?.text = monster.subtitle
return cell
}
Try this
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
let monster = monsters[indexPath.row]
cell.textLabel?.text = monster.name
cell.detailTextLabel?.text = monster.subtitle
let label = UILabel.init(frame: CGRect(x:0,y:0,width:100,height:20))
label.text = monster.name
cell.accessoryView = label
return cell
}
Click on your tableView cell. It's easier to do it in document outline.
Change the style attribute in Attribute Inspector from Basic to Custom. You will now be able to add a label. The basic template is set, so you can't alter it. I believe this was the issue you were having.
I'm sure after you place the label you know what to do, but just in case:
Place the new label at the right margin of the cell and pin it to the top, bottom, and right, using Autolayout.
Reconnect your title, subtitle IBOutlets, and create a right label IBOutlet, connect it, and you should be done.
In Xcode 8 with Swift 3 I'm using custom cell with auto layout. Information into cell inserted from JSON, so my code looks like:
//the method returning each cell of the list
public override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
let cell = self.tableView.dequeueReusableCell(withIdentifier: "Feedcell", for: indexPath) as! FruitTableViewCell
//getting the hero for the specified position
let hero: List_Feed
hero = heroes[indexPath.row]
cell.labelAnswer.text = hero.answer
cell.labelQuestion.lineBreakMode = .byWordWrapping
cell.labelQuestion.text = hero.question
cell.labelQuestion.sizeToFit()
cell.labelAnswer.sizeToFit()
return cell
}
Problem is that I'm getting equal labelQuestion heigh for each cell, but text size and line size are different. How to solve this? :c
As Cell is reusing the Label You have to empty label before use for next cell
public override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell{
let cell = self.tableView.dequeueReusableCell(withIdentifier: "Feedcell", for: indexPath) as! FruitTableViewCell
//EMPTY LABELS
cell.labelAnswer.text = ""
cell.labelQuestion.text = ""
self.layoutIfNeeded()
//getting the hero for the specified position
let hero: List_Feed
hero = heroes[indexPath.row]
cell.labelAnswer.text = hero.answer
cell.labelQuestion.lineBreakMode = .byWordWrapping
cell.labelQuestion.text = hero.question
cell.labelQuestion.sizeToFit()
cell.labelAnswer.sizeToFit()
return cell
}
Hope it is helpful to you
1- set vertical content hugging priority off today label to 1000
2- hook the bottom of the label [ that is under today label ] to the top of the imageView Below it
3- hook bottom of the most-down label to bottom of contentView
Edit :
Add this 2 lines before return cell in cellForRowAt
cell.layoutSubviews()
cell.layoutIfNeeded()
This is happening but I don't know why. It is a standard tableviewcell with a label and an image on it
Here is the code:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = patientsTableView.dequeueReusableCell(withIdentifier: "patientTableViewCell", for: indexPath)
let text = "Bob Marley"
cell.textLabel?.text = text
return cell
}
When I do not put an image view in the object inspector but like below, it solves the problem. I am not sure why though
cell.imageView?.image = UIImage(named: "patients")
I am using dynamic height for tableview cells and Haneke for downloading and caching image using the following code:
override func viewDidLoad() {
super.viewDidLoad()
myTableView.rowHeight = UITableViewAutomaticDimension
myTableView.estimatedRowHeight = 500
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:ImageCellTableViewCell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! ImageCellTableViewCell;
cell.myImageView.hnk_setImage(from: URL(string: imageUrl), placeholder: nil)
return cell
}
Here I need to resize the cell height when setting image after downloading.
How can I resize the tableview cell after downloading the image.
Just call
tableView.beginUpdates()
tableView.endUpdates()
after image is downloaded and height constraint is set. Hope this helps!
EDIT:
Another option, to give the right height to the cell, would be receiving the image size from the server. This way you could feed table with just right calculated cell height.
just add the proper constraint to your image, for example , top and left constraint with, aspect ratio constraint.(you can do it even in your storyboard interface)
Set table view's row height like:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:ImageCellTableViewCell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! ImageCellTableViewCell;
cell.myImageView.hnk_setImage(from: URL(string: imageUrl), placeholder: nil)
tableView.rowHeight = cell.myImageView.frame.origin.y + cell.myImageView.frame.size.height + (constant what every you want to give like: - 20/30 as per your need)
return cell
}
I am adding cell like below. Before selecting cell, only textLabel is able to be seen, after selection detailTextLabel getting appear too. Why detailTextLabel not on screen from beginning?
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("ooo", forIndexPath: indexPath) as UITableViewCell
cell.textLabel!.textColor = UIColor.whiteColor()
cell.textLabel!.text = "asdf1"
cell.detailTextLabel!.textColor = UIColor.whiteColor()
cell.detailTextLabel!.text = "asdf2"
return cell
}
