从UIScreen.main.bounds确定UIInputViewController的安全区域

import UIKit

class MyInputViewController: UIInputViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let screenBounds = UIScreen.main.bounds
        let safeAreaInsets = view.safeAreaInsets
        
        let safeAreaFrame = CGRect(x: screenBounds.origin.x + safeAreaInsets.left,
                                   y: screenBounds.origin.y + safeAreaInsets.top,
                                   width: screenBounds.size.width - safeAreaInsets.left - safeAreaInsets.right,
                                   height: screenBounds.size.height - safeAreaInsets.top - safeAreaInsets.bottom)
        
        // 使用safeAreaFrame来布局UIInputViewController的内容
    }
}
