I am trying to programmatically create a NSTextField that has the NSFont.TextStyle.headline font style. This font can also be set from the font drop down menu in the storyboard.
However, when I do the following:
let attributes: [NSAttributedString.Key : Any] = [NSAttributedString.Key.font : NSFont.TextStyle.headline]
let attributedString = NSAttributedString(string: product.url, attributes: attributes)
let textLabel = NSTextField(labelWithAttributedString: attributedString)
My app crashes with the following error:
-[__NSCFConstantString pointSize]: unrecognized selector sent to instance 0x7fff8064f918
We need to get the corresponding font associated with the text style.
Pass these constants to preferredFont(forTextStyle:options:) or preferredFontDescriptor(forTextStyle:options:) to retrieve the corresponding font or font descriptor.
Therefore:
let attributes: [NSAttributedString.Key : Any] = [NSAttributedString.Key.font : NSFont.preferredFont(forTextStyle: NSFont.TextStyle.headline, options: [:])]
How can I build something like this using attributed text? I tried adding line feed (\n), it didn't work, just displayed first line and cropped next two, removing \n will display two parts in single line:
let mutableAttributedString = NSMutableAttributedString()
let regularAttribute = [NSAttributedStringKey.font: UIFont(name: "Avenir-Light", size: 45.0), NSAttributedStringKey.foregroundColor: UIColor.yellow]
let boldAttribute = [NSAttributedStringKey.font: UIFont(name: "Avenir-Light", size: 25.0), NSAttributedStringKey.foregroundColor: UIColor.white]
let mutableAttributedString2 = NSMutableAttributedString()
let boldAttributedString = NSAttributedString(string: "person", attributes: boldAttribute)
let regularAttributedString = NSAttributedString(string: "\(self.requestCount)", attributes: regularAttribute)
mutableAttributedString2.append(boldAttributedString)
mutableAttributedString2.append(NSAttributedString(string: "\n"))
mutableAttributedString2.append(regularAttributedString)
self.btnStatsPeople.setAttributedTitle(mutableAttributedString2, for: .normal)
UILabel has one line by default.
This property controls the maximum number of lines to use in order to
fit the label’s text into its bounding rectangle. The default value
for this property is 1. To remove any maximum limit, and use as many
lines as needed, set the value of this property to 0.
UIButton creates default UILabel. So using 0 lines is a solution for your problem:
self.btnStatsPeople.titleLabel?.numberOfLines = 0
I currently have:
#IBOutlet var label: WKInterfaceLabel!
and
let myString = "Swift Attributed String"
let myAttribute = [ NSAttributedStringKey.foregroundColor: UIColor.blue ]
let myAttrString = NSAttributedString(string: myString, attributes: myAttribute)
label.setAttributedText(myAttrString)
Currently this code does not change the text of the label. Is there something obvious I am missing? Thanks for any help!
Your code is working perfectly fine but for only textcolor
You do not need to use attributed property you can directly use setTextColor() property.
label.setTextColor(UIColor.blue)
label.setText(myString)
You can refer WKInterfaceLabel and setTextColor
cell!.textLabel?.text = vehicle["vrn"].string
cell?.detailTextLabel?.text = stateString
I want to display stateString as bold and also tried to use textLabel instead of detailedText but it did not work.
You can set the font property of the detailTextLabellike so:
cell.detailTextLabel?.font = UIFont.boldSystemFontOfSize(15.0)
You can use the font property inside the UILabel class.
// You need to set the name of your font here
cell.detailTextLabel?.font = UIFont(name:"HelveticaNeue-Bold", size: 16.0)
There are other options using the attributedText
property but implies a little more of code, something like this:
// Define attributes to set
let labelFont = UIFont(name: "HelveticaNeue-Bold", size: 16)
let attributes :Dictionary = [NSFontAttributeName : labelFont]
// Create the attributed string
var attrString = NSAttributedString(string: "textOfYourLabel", attributes:attributes)
cell.detailTextLabel?.attributedText = attrString
I hope this help you.
If you want to bold text label using story board, simply select SHADOW colour in attributes inspector to same of that Text colour. Its works for me try it....
How can I underline text in a UITextView. I understand that I would need to create a subclass of UITextView, but what would go under drawRect:?
Thanks.
Try to use NSAttributedString as follows and set in UITextView. This works for iOS6.
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:#"Some String"];
[attString addAttribute:(NSString*)kCTUnderlineStyleAttributeName
value:[NSNumber numberWithInt:kCTUnderlineStyleSingle]
range:(NSRange){0,[attString length]}];
For more info on NSAttributedString check this How do you use NSAttributedString?
For eg:-
textView.attributedText = attString;
From apple documentation on UITextView,
In iOS 6 and later, this class supports multiple text styles through
use of the attributedText property. (Styled text is not supported in
earlier versions of iOS.) Setting a value for this property causes the
text view to use the style information provided in the attributed
string. You can still use the font, textColor, and textAlignment
properties to set style attributes, but those properties apply to all
of the text in the text view.
attributedText:
The styled text displayed by the text view.
#property(nonatomic,copy) NSAttributedString *attributedText
Discussion: This property is nil by default. Assigning a new value to this property also replaces the value of the text property with the same string data, albeit without any formatting information. In addition, assigning a new a value updates the values in the font, textColor, and textAlignment properties so that they reflect the style information starting at location 0 in the attributed string.
If you want to avoid having to include CoreText, you can utilize an attributed string with this attribute:
#{NSUnderlineStyleAttributeName: #(NSUnderlineStyleSingle)}
If this is static text, you can underline it in Interface Builder. Make sure to make the text 'Attributed' first by selecting 'Attributed' in the drop down menu:
textViewMessage.linkTextAttributes = #{NSForegroundColorAttributeName: [UIColor blueColor], NSUnderlineStyleAttributeName: [NSNumber numberWithInt:NSUnderlineStyleSingle]};
If you want to format your text (with underlined words, links, colored words...) I suggest you to use FTCoreText
-(IBAction)underline:(id)sender
{
NSDictionary *underlineAttribute = #{NSUnderlineStyleAttributeName: #(NSUnderlineStyleSingle)};
texts.attributedText = [[NSAttributedString alloc] initWithString:texts.text
attributes:underlineAttribute];
}
You can't use "kCTUnderlineStyleAttributeName" or "kCTUnderlineStyleSingle"
Now you must do it like this:
NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:#"Text"];
[attString addAttribute:NSUnderlineStyleAttributeName
value:#(NSUnderlineStyleSingle)
range:(NSRange){0,[attString length]}];
If you are using iOS 6 then you can use the attributedText attribute of UITextView. Apply underline formatting to the text. You can also set the typingAttributes property to ensure the text that the user types has a specific set of formatting if you wish.
I recommend you to use CoreText. A Basic tutorial is here on raywenderlich.
I recommend you to use MFUnderlinedTextView, it will be helpful.
This is how I did it using Swift 5:
let attributedString = NSMutableAttributedString(string: myTextView.text ?? "")
myTextView.linkTextAttributes = [NSAttributedString.Key(rawValue: NSAttributedString.Key.underlineStyle.rawValue): NSUnderlineStyle.single.rawValue] as [NSAttributedString.Key: Any]?
myTextView.attributedText = attributedString
Swift 5.
As my UITextView if for inserting text, I created an extension function as bellow.
extension UITextView {
func underlined() {
let border = CALayer()
let width = CGFloat(1.0)
border.borderColor = UIColor.lightGray.cgColor
border.frame = CGRect(x: 0, y: self.frame.size.height - 5, width: self.frame.size.width, height: 1)
border.borderWidth = width
self.layer.addSublayer(border)
self.layer.masksToBounds = true
let style = NSMutableParagraphStyle()
style.lineSpacing = 15
let attributes = [NSAttributedString.Key.paragraphStyle : style, NSAttributedString.Key.foregroundColor : UIColor.darkGray, NSAttributedString.Key.font : UIFont.systemFont(ofSize: 13)]
self.attributedText = NSAttributedString(string: self.text, attributes: attributes)
}
}
The border is drawling the line and the style is adding the spacing between the lines.
Usage in your UIView custom layout:
override func layoutSubviews() {
super.layoutSubviews()
self.dateAndTimeInput.underlined()
}
Image with the result
let someString = NSMutableAttributedString(string: "Your String", attributes: [NSAttributedString.Key.font : UIFont.boldSystemFont(ofSize: 20), NSAttributedString.Key.underlineStyle : NSUnderlineStyle.single.rawValue])
someStringTextView.attributedText = titleAT
U can just give your string a bunch of attributes like bold, underlined etc.
To underline a text, you have to go where you can select copy, cut , delete options there are now more options like B/I/U( bold, italic, underline). Choose this option and this is it. And to unable it, choose underline option again.
