我在storyBorad中使用UIVisual Effect視圖。我只是將四個約束(頂部,底部,左側,右側)設置爲該視圖。但它看起來有些黑色背後。無法獲得模糊效果
源代碼:
import UIKit
class SignOutViewController: UIViewController {
@IBOutlet weak var signouTitle: UILabel!
@IBOutlet weak var desc1: UILabel!
@IBOutlet weak var desc2: UILabel!
@IBOutlet weak var cancelButton: UIButton!
@IBOutlet weak var sureButton: UIButton!
@IBOutlet weak var alertView: UIView!
@IBOutlet weak var seperatorView: UIView!
@IBOutlet weak var buttonsSuperView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
prepareAlertView()
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
alertView.layer.cornerRadius = alertView.frame.height * 0.05
}
private func prepareAlertView() -> Void{
signouTitle.text = "Sign Out"
desc1.text = "Do you really want to sign out"
desc2.text = "from this account"
signouTitle.textColor = UIColor(red: 1/255, green: 170/255, blue: 112/255, alpha: 1)
desc1.textColor = UIColor(red: 195/255, green: 195/255, blue: 195/255, alpha: 1)
desc2.textColor = UIColor(red: 195/255, green: 195/255, blue: 195/255, alpha: 1)
cancelButton.setAttributedTitle(NSAttributedString(string: "Cancel", attributes: [NSFontAttributeName: UIFont.getProximaNovaSemibold(size: 16), NSForegroundColorAttributeName: UIColor.white]), for: .normal)
sureButton.setAttributedTitle(NSAttributedString(string: "Sure", attributes: [NSFontAttributeName: UIFont.getProximaNovaSemibold(size: 16), NSForegroundColorAttributeName: UIColor.white]), for: .normal)
self.view.backgroundColor = UIColor.black.withAlphaComponent(0.65)
buttonsSuperView.backgroundColor = UIColor(red: 1/255, green: 170/255, blue: 112/255, alpha: 1)
alertView.backgroundColor = UIColor(red: 36/255, green: 36/255, blue: 40/255, alpha: 1)
}
@IBAction func cancelTapped(_ sender: Any) {
self.dismiss(animated: true, completion: nil)
}
@IBAction func sureTapped(_ sender: Any) {
}
}
我加入UIVisual effectView編程方式。我需要visualEffect作爲viewHierarchy中的第-1個位置。但它作爲響應相同..
