iOS 强制输入圆角和眩光

在iOS开发中，我们经常需要对视图的外观进行一些定制化处理，其中包括圆角和眩光效果。本文将介绍如何 强制输入圆角和眩光效果的方法，并提供相关代码示例。

swift
import UIKit
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let button = UIButton(frame: CGRect(x: 100, y: 100, width: 200, height: 50))
        button.backgroundColor = UIColor.blue
        button.setTitle("圆角按钮", for: .normal)
        button.layer.cornerRadius = 10 // 设置圆角半径
        button.layer.masksToBounds = true // 开启剪裁
        
        self.view.addSubview(button)
    }
}

swift
import UIKit
class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let view = UIView(frame: CGRect(x: 100, y: 100, width: 200, height: 200))
        
        let gradientLayer = CAGradientLayer()
        gradientLayer.frame = view.bounds
        gradientLayer.colors = [UIColor.white.cgColor, UIColor.clear.cgColor]
        gradientLayer.startPoint = CGPoint(x: 0, y: 0)
        gradientLayer.endPoint = CGPoint(x: 1, y: 1)
        
        view.layer.addSublayer(gradientLayer)
        
        self.view.addSubview(view)
    }
}
