Swift Package Manager

Add the following to the dependencies of your Package.swift:

.package(url: "https://github.com/lixiang1994/AttributedString.git", from: "version")

Usage

First make sure to import the framework:

import AttributedString

How to initialize:

// Normal
let a: ASAttributedString = .init("lee", .font(.systemFont(ofSize: 13)))
// Interpolation
let b: ASAttributedString = "\("lee", .font(.systemFont(ofSize: 13)))"

Here are some usage examples. All devices are also available as simulators:

Font:

textView.attributed.text = """

\("fontSize: 13", .font(.systemFont(ofSize: 13)))

\("fontSize: 20", .font(.systemFont(ofSize: 20)))

\("fontSize: 22 weight: semibold", .font(.systemFont(ofSize: 22, weight: .semibold)))

"""

ForegroundColor:

textView.attributed.text = """

\("foregroundColor", .foreground(.white))

\("foregroundColor", .foreground(.red))

"""

Strikethrough:

textView.attributed.text = """

\("strikethrough: single", .strikethrough(.single))

\("strikethrough: double color: .red", .strikethrough(.double, color: .red))

"""

Attachment: (Does not include watchOS)

// ASAttributedString.Attachment

textView.attributed.text = """

\(.data(xxxx, type: "zip"))

\(.file(try!.init(url: .init(fileURLWithPath: "xxxxx"), options: [])))

\(.attachment(NSTextAttachment()))

"""

Attachment Image: (Does not include watchOS)

// ASAttributedString.ImageAttachment

textView.attributed.text = """

\(.image(UIImage(named: "xxxx")))

\(.image(UIImage(named: "xxxx"), .custom(size: .init(width: 200, height: 200))))

\(.image(UIImage(named: "xxxx"), .proposed(.center))).

"""

Attachment Async Image: (Only supports iOS: UITextView)

// ASAttributedString.AsyncImageAttachment

textView.attributed.text = """

\(.image(url, placeholder: xxxxx))

"""

Custom loader:

ASAttributedString.AsyncImageAttachment.Loader = AsyncImageAttachmentKingfisherLoader.self

Please read the demo AttachmentViewController.swift file for details.

Attachment View: (Only supports iOS: UITextView)

// ASAttributedString.ViewAttachment

textView.attributed.text = """

\(.view(xxxxView))

\(.view(xxxxView, .custom(size: .init(width: 200, height: 200))))

\(.view(xxxxView, .proposed(.center))).

"""

Wrap:

let a: ASAttributedString = .init("123", .background(.blue))
let b: ASAttributedString = .init("456", .background(.red))
textView.attributed.text = "\(wrap: a) \(wrap: b, .paragraph(.alignment(.center)))"

// Defalut embedding mode, Nested internal styles take precedence over external styles
textView.attributed.text = "\(wrap: a, .paragraph(.alignment(.center)))"
textView.attributed.text = "\(wrap: .embedding(a), .paragraph(.alignment(.center)))"
// Override mode, Nested outer style takes precedence over inner style
textView.attributed.text = "\(wrap: .override(a), .paragraph(.alignment(.center)))"

Append:

let a: ASAttributedString = .init("123", .background(.blue))
let b: ASAttributedString = .init("456", .background(.red))
let c: ASAttributedString = .init("789", .background(.gray))
textView.attributed.text = a + b
textView.attributed.text += c

Checking:

var string: ASAttributedString = .init("my phone number is +86 18611401994.", .background(.blue))
string.add(attributes: [.foreground(color)], checkings: [.phoneNumber])
textView.attributed.text = string
var string: ASAttributedString = .init("open https://www.apple.com and https://github.com/lixiang1994/AttributedString", .background(.blue))
string.add(attributes: [.foreground(color)], checkings: [.link])
textView.attributed.text = string
var string: ASAttributedString = .init("123456789", .background(.blue))
string.add(attributes: [.foreground(color)], checkings: [.regex("[0-6]")])
textView.attributed.text = string

Action: (Only supports iOS: UILabel / UITextView & macOS: NSTextField)

For complex styles, it is recommended to use UITextView.

UITextview needs to set isEditable and isSelectable to false.

Click:
// Text
let a: ASAttributedString = .init("lee", .action({  }))
// Attachment (image)
let b: ASAttributedString = .init(.image(image), action: {
    // code
})

// It is recommended to use functions as parameters.
func clicked() {
    // code
}
// Normal
let c: ASAttributedString = .init("lee", .action(clicked))
let d: ASAttributedString = .init(.image(image), action: clicked)
// Interpolation
let e: ASAttributedString = "\("lee", .action(clicked))"
let f: ASAttributedString = "\(.image(image), action: clicked)"

// More information. 
func clicked(_ result: ASAttributedString.Action.Result) {
    switch result.content {
    case .string(let value):
       	print("Currently clicked text: \(value) range: \(result.range)")
				
    case .attachment(let value):
        print("Currently clicked attachment: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Label", .font(.systemFont(ofSize: 20)), .action(clicked))"
textView.attributed.text = "This is a picture \(.image(image, .custom(size: .init(width: 100, height: 100))), action: clicked) Displayed in custom size."
Press:
func pressed(_ result: ASAttributedString.Action.Result) {
    switch result.content {
    case .string(let value):
        print("Currently pressed text: \(value) range: \(result.range)")
                
    case .attachment(let value):
        print("Currently pressed attachment: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Long Press", .font(.systemFont(ofSize: 20)), .action(.press, pressed))"
textView.attributed.text = "This is a picture \(.image(image, .custom(size: .init(width: 100, height: 100))), trigger: .press, action: pressed) Displayed in custom size."
Highlight style:
func clicked(_ result: ASAttributedString.Action.Result) {
    switch result.content {
    case .string(let value):
        print("Currently clicked text: \(value) range: \(result.range)")
                
    case .attachment(let value):
        print("Currently clicked attachment: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Label", .font(.systemFont(ofSize: 20)), .action([.foreground(.blue)], clicked))"
Custom:
let custom = ASAttributedString.Action(.press, highlights: [.background(.blue), .foreground(.white)]) { (result) in
    switch result.content {
    case .string(let value):
        print("Currently pressed text: \(value) range: \(result.range)")
        
    case .attachment(let value):
        print("Currently pressed attachment: \(value) range: \(result.range)")
    }
}

label.attributed.text = "This is \("Custom", .font(.systemFont(ofSize: 20)), .action(custom))"
textView.attributed.text = "This is a picture \(.image(image, .original(.center)), action: custom) Displayed in original size."

Observe: (Only supports iOS: UILabel / UITextView & macOS: NSTextField)

label.attributed.observe([.phoneNumber], highlights: [.foreground(.blue)]) { (result) in
    print("Currently clicked \(result)")
}

textView.attributed.observe([.link], highlights: [.foreground(.blue)]) { (result) in
    print("Currently clicked \(result)")
}

For more examples, see the sample application.
