var testLabel = UILabel(frame: CGRectMake(8,0,tableView.frame.width-8,100))
let testDesc = "dsfdddfdsfdsfsdfdsfdsfdsfdsfdsfsdfdsfsdfsdfdsfdsfdsfdsfdsfdsfdsfdsfdsfdsfdsfdsfdsf"
var labelString = indexString + ". " + testDesc
testLabel.text = labelString
testLabel.lineBreakMode = .ByWordWrapping // or NSLineBreakMode.ByWordWrapping
testLabel.numberOfLines = 0
retCell.addSubview(testLabel)
My output:
1. ksajdkasdsajdksajdksajd
asjdkjassadkasldkalsdklsakdl
How can make my output like the following:
1. asdasdasdasdasdasdasds
djaskdjsadjksadasjdjas
Here is the code that I used
let paragraph = NSMutableParagraphStyle()
paragraph.firstLineHeadIndent = 0
paragraph.headIndent = 8 //You can change this to whatever indent you want
let mutString = NSAttributedString(
string: "this is a test but I need this to be long so it flows onto multiple lines so I will keep going",
attributes: [NSAttributedStringKey.paragraphStyle: paragraph]
)
mainLabel.attributedText = mutString
Make an attributed string (NSMutableAttributedString) and set its paragraph style's firstLineHeadIndent and headIndent as desired. Now set the label's attributedText to that attributed string.

I'm using UIKit, not SwiftUI. Previously, I used setAttributedTitle and I also set AdjustsFontSizeToFitWidth to true, and the font size shrinks to match the button width. I can't seem to match this behavior with the new button configurations and swift's AttributedString.
Here's what I have:
var config = UIButton.Configuration.filled()
config.imagePadding = 5
config.imagePlacement = .trailing
config.image = UIImage(systemName: "ellipsis.circle",
withConfiguration: UIImage.SymbolConfiguration(scale: .medium))
config.titlePadding = 10
config.cornerStyle = .capsule
let handler: UIButton.ConfigurationUpdateHandler = { button in
button.configuration?.background.backgroundColor = Colors.specLabel
button.configuration?.baseForegroundColor = Colors.greyText
}
myButton.configuration = config
myButton.configurationUpdateHandler = handler
And then
guard let attributedString = try? AttributedString(markdown: "hello **hello** hello") else { return }
myButton.configuration?.attributedTitle = attributedString
Every time, I get a multi-line button. Setting numberOfLines, lineBreakMode and adjustsFontSizeToFitWidth is all ignored. Any ideas?
I have two UIButton if I click onto button1 the value of label1 is 250, if I click again onto button1 the value of label1 should be 0. The same logic is applied to my button2 and label2. I want to store the addition of label1 and label2 into label3. . My code is:
func PickUpCarCost() {
if (!isclick){
imgCheck.image = UIImage(named: "check.png")
isclick=true
//Pickup fare conver into integer
let PickUp = String(self.PickUpPrice)
PickUpFare.text = PickUp
self.pickCost = Int( PickUpFare.text!)
self.PAyAmount = ((self.PayFareWithSecurity)+(self.pickCost))
print("PaybleAmount: \(self.PAyAmount)")
self.AmountPay1 = ((self.PAyAmount)+(self.DeliverCost))
PaybleAmount.text=String(self.AmountPay1!)
}
else
{
imgCheck.image = UIImage(named: "uncheck.png")
PickUpFare.text = "0"
self.PickUpElse=Int(PickUpFare.text!)
print("PickUpElse: \(self.PickUpElse)")
self.PAyAmount = (self.PayFareWithSecurity)+(self.PickUpElse)
PaybleAmount.text=String(self.PAyAmount!)
isclick=false
}
}
func CarDeliverCost() {
if (!isclick){
imgUnCheck.image = UIImage(named: "check.png")
isclick=true
let DeliverPrice = String(self.deliveryPrice)
DeliverFare.text = DeliverPrice
self.DeliverCost = Int(DeliverFare.text!)
self.PAyAmount = ((self.PayFareWithSecurity)+(self.DeliverCost))
print("PaybleAmount: \(self.PAyAmount)")
PaybleAmount.text=String(self.PAyAmount!)
}
else
{
imgUnCheck.image = UIImage(named: "uncheck.png")
let deliveryelse = String(0)
DeliverFare.text = deliveryelse
self.deliver = Int(DeliverFare.text!)
PaybleAmount.text=String(self.PAyAmount!)
isclick=false
}
}
The first issue that you're facing is that you are using the same boolean isClick for two different scenarios. Your logic is that the user could decide to click onto both buttons or a single one. So if I click onto the first button then your flag is turn on, since the second button also uses the same boolean then you'll get that uncheck behavior automatically.
Thus you should use two different booleans such as hasPressOntoFirstButton and hasPressOntoSecondButton, where both set to false at the beginning, and each variable is used in their respective scene.
You mentioned that you want to add the label1 to label2, the easier way would be add the variable that set these labels. i.e
let label1 = UILabel()
let label2 = UILabel()
let label3 = UILabel()
let data1: Double = 83.0
let data2: Double = 82.0
var total: Double { // have a computed variable to adds automatically
return data1 + data2
}
label1.text = "\(data1)"
label2.text = "\(data2)"
label3.text = "\(data1 + data2)" // or "\(total)"
Remarks:
(1) your naming convention are really misleading, you should separate UI object naming from data. i.e you can have deliveryFareLabel.text instead of DeliverFare.text
(2) avoid using !, unwrapped all optional using either nil coalescing ??, or if let or guard statements
How to do to get the selected string from a NSTextView in Swift?
// create a range of selected text
let range = mainTextField.selectedRange()
// this works but I need a plain string not an attributed string
let str = mainTextField.textStorage?.attributedSubstring(from: range)
Maybe I have to add an intermediate step where I get the full string and then apply the range on it?
What about
let str = mainTextField.text.substring(with: range)
Edit:
This should work now:
let range = mainTextField.selectedRange() // Returns NSRange :-/ (instead of Range)
let str = mainTextField.string as NSString? // So we cast String? to NSString?
let substr = str?.substring(with: range) // To be able to use the range in substring(with:)
The code snippet in the Swift 5. That's not very hard but repeated
let string = textView.attributedString().string
let selectedRange = textView.selectedRange()
let startIndex = string.index(string.startIndex, offsetBy: selectedRange.lowerBound)
let endIndex = string.index(string.startIndex, offsetBy: selectedRange.upperBound)
let substring = textView.attributedString().string[startIndex..<endIndex]
let selectedString = String(substring)
In case anyone is having issues with the selectedRanges() not returning the proper range for an NSTextView, make sure that you have made your NSTextView selectable. I don't know if it's not selectable by default but I had to enable it;
textView.isSelectable = true
I was trying this in Swift 5 using #user25917 code sample above and I couldn't get the ranges no matter what. I was getting a visual confirmation the text was selected through highlighting which threw me off. This was driving me mad for a few hours.
This may be helpfull for you :
let textView = NSTextView(frame: NSMakeRect(0, 0, 100, 100))
let attributes = [NSForegroundColorAttributeName: NSColor.redColor(),
NSBackgroundColorAttributeName: NSColor.blackColor()]
let attrStr = NSMutableAttributedString(string: "my string", attributes: attributes)
let area = NSMakeRange(0, attrStr.length)
if let font = NSFont(name: "Helvetica Neue Light", size: 16) {
attrStr.addAttribute(NSFontAttributeName, value: font, range: area)
textView.textStorage?.appendAttributedString(attrStr)
}
How do you set the line-spacing for a multi-line NSTextField programmatically with Swift or within the Interface Builder?
You can use NSAttributedString to modify this (Swift 4 example):
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.lineSpacing = 10.0 // sets the space BETWEEN lines to 10 points
paragraphStyle.maximumLineHeight = 12.0 // sets the MAXIMUM height of the lines to 12 points
let text = "Your text"
let attributes = [.paragraphStyle: paragraphStyle]
textField.attributedStringValue = NSAttributedString(string: text, attributes: attributes)
Sorry for a basic question, but I'm not sure where to start. Is the following possible in Swift?
In a UITextView (Not a label, as in the possible duplicate), different bits of text having different formatting: for instance, a line of large text in the same UITextView as a line of small text. Here is a mockup of what I mean:
Is this possible in one UITextView?
You should have a look at NSAttributedString. Here's an example of how you could use it:
let largeTextString = "Here is some large, bold text"
let smallTextString = "Here is some smaller text"
let textString = "\n\(largeTextString)\n\n\(smallTextString)"
let attrText = NSMutableAttributedString(string: textString)
let largeFont = UIFont(name: "Arial-BoldMT", size: 50.0)!
let smallFont = UIFont(name: "Arial", size: 30.0)!
// Convert textString to NSString because attrText.addAttribute takes an NSRange.
let largeTextRange = (textString as NSString).range(of: largeTextString)
let smallTextRange = (textString as NSString).range(of: smallTextString)
attrText.addAttribute(NSFontAttributeName, value: largeFont, range: largeTextRange)
attrText.addAttribute(NSFontAttributeName, value: smallFont, range: smallTextRange)
textView.attributedText = attrText
The result:
