iOS26适配指南之UIButton
2025年8月17日 17:05
介绍
在 iOS 26 中，UIButton 迎来了两项非常实用的更新：
- Liquid Glass 风格配置方法 — 让按钮拥有全新的半透明折射质感，完美融入 iOS 26 的视觉系统。
- Symbol 动画切换 — 通过 symbolContentTransition 实现更顺滑的 SF Symbols 切换效果。
适配 Liquid Glass
UIButton.Configuration 增加了符合 Liquid Glass 风格的配置方法：glass()、clearGlass()、prominentGlass()与prominentClearGlass()。
代码
import UIKit
class ViewController: UIViewController {
let configs: [UIButton.Configuration] = {
[
{
// iOS26新增
var config = UIButton.Configuration.glass()
config.title = "喜欢"
config.image = UIImage(systemName: "heart")
return config
}(),
{
// iOS26新增
var config = UIButton.Configuration.clearGlass()
config.title = "收藏"
config.image = UIImage(systemName: "star")
return config
}(),
{
// iOS26新增
var config = UIButton.Configuration.prominentGlass()
config.title = "分享"
config.image = UIImage(systemName: "square.and.arrow.up")
return config
}(),
{
// iOS26新增
var config = UIButton.Configuration.prominentClearGlass()
config.title = "下载"
config.image = UIImage(systemName: "arrow.down.circle")
return config
}()
]
}()
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .systemGray
for (index, config) in configs.enumerated() {
let button = UIButton(frame: CGRect(x: 120, y: 220 + CGFloat(index) * 70, width: 160, height: 60))
button.configuration = config
view.addSubview(button)
}
}
}
效果
symbolContentTransition
UIButton.Configuration 增加了类型UISymbolContentTransition?的属性symbolContentTransition，用于切换 SF Symbols 图标，并且可以呈现切换动画。
代码
import UIKit
class ViewController: UIViewController {
let button = UIButton(frame: CGRect(x: 100, y: 200, width: 200, height: 200))
override func viewDidLoad() {
super.viewDidLoad()
var config = UIButton.Configuration.plain()
config.image = UIImage(systemName: "heart.circle")
config.preferredSymbolConfigurationForImage = UIImage.SymbolConfiguration(pointSize: 50, weight: .thin)
// iOS26新增
config.symbolContentTransition = UISymbolContentTransition(.replace, options: .speed(0.1))
button.configuration = config
button.isSymbolAnimationEnabled = true
button.tintColor = .systemRed
view.addSubview(button)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
button.configuration?.image = UIImage(systemName: "heart.circle.fill")
}
}
