How to Use
To utilize Tangram-iOS in your project, follow these steps:
Step 1: Add Dependency
dependencies: [
.package(url: "https://github.com/Wen-Li/tangram-ios", from: "0.1.0")
]
Step 2: Import Tangram
import tangram
Step 3: Dynamic Page Creation
class MyViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Define page structure using JSON data
let data = """
{
"components": [
{
"type": "text",
"text": "Hello, world!"
}
]
}
""".data(using: .utf8)!
let page = Tangram.parse(data)
// Dynamic page generation using code
let page = Tangram.page()
page.add(Tangram.text("Hello, world!"))
// Display the page
view.addSubview(page)
}
}
Advantages
- Simplicity: Tangram-iOS simplifies dynamic page building with easy dependency setup and usage.
- Rich Functionality: It supports defining page structures using JSON data, dynamic page generation with code, page reuse, and caching.
- Compatibility: Tangram-iOS is compatible with iOS 10 and later versions.
Example
Here's a complete example of using Tangram-iOS:
// Add Dependency
dependencies: [

{
"components": [
{
"type": "text",
"text": "Hello, world!"
}
]
}
""".data(using: .utf8)!
let page = Tangram.parse(data)
// Dynamic page generation using code
let page = Tangram.page()
page.add(Tangram.text("Hello, world!"))
// Display the page
view.addSubview(page)
// Set page styles
page.style = TangramStyle(
background: UIColor.red,
text: TangramTextStyle(
color: UIColor.white,
fontSize: 18
)
)
}
}
