AttributedText
AttributedText is a Swift µpackage that provides NSAttributedString
rendering in SwiftUI by wrapping either an NSTextView
or a UITextView
depending on the platform.
Supported Platforms
- macOS 11.0+
- iOS 14.0+
- tvOS 14.0+
Usage
import AttributedText
struct ContentView: View {
private let attributedString: NSAttributedString = {
let result = NSMutableAttributedString(
string: """
After the Big Bang
A brief summary of time
Life on earth
10 billion years
You reading this
13.7 billion years
"""
)
result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .title1)], range: NSRange(location: 0, length: 18))
result.addAttributes([.link: URL(string: "https://en.wikipedia.org/wiki/Big_Bang")!], range: NSRange(location: 10, length: 8))
result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .body)], range: NSRange(location: 19, length: 23))
result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .title2)], range: NSRange(location: 43, length: 13))
result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .body)], range: NSRange(location: 57, length: 16))
result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .title2)], range: NSRange(location: 74, length: 16))
result.addAttributes([.font: UIFont.preferredFont(forTextStyle: .body)], range: NSRange(location: 91, length: 18))
return result
}()
var body: some View {
AttributedText(attributedString)
.background(Color.gray.opacity(0.5))
.accentColor(.purple)
}
}
An AttributedText
view takes all the available width and adjusts its height to fit the contents.
To change the text alignment or line break mode, you need to add a .paragraphStyle
attribute to the attributed string.
