我想圓一個UIVisualEffectView像這樣的兩個上角:UIVisualEffectView面膜不工作在iPhone上7加模擬器
if let tabBarHeight = self.tabBarController?.tabBar.frame.height {
mainViewHeight = self.view.frame.height - tabBarHeight
}
let oneAndHalfMainViewHeight = mainViewHeight * 1.5
midStateHeight = mainViewHeight/2 - midStateConstant
let blur = UIBlurEffect(style: .dark)
slideView = UIVisualEffectView(effect: blur)
slideView.translatesAutoresizingMaskIntoConstraints = false
slideView.contentView.backgroundColor = Tools.colorPicker(2, alpha: 1)
self.view.addSubview(slideView)
let slideViewHorizontalConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:|[slideView(\(UIScreen.main.bounds.width))]|", options: NSLayoutFormatOptions(), metrics: nil, views: ["slideView" : slideView])
slideViewHeightConstraint = NSLayoutConstraint(item: slideView, attribute: .height, relatedBy: .equal, toItem: nil, attribute: .notAnAttribute, multiplier: 1, constant: oneAndHalfMainViewHeight)
slideViewTopConstraint = NSLayoutConstraint(item: self.view, attribute: .bottom, relatedBy: .equal, toItem: slideView, attribute: .top, multiplier: 1, constant: alwaysVisibleHeight)
self.view.addConstraints(slideViewHorizontalConstraints)
guard let slideViewHeightConstraint = slideViewHeightConstraint, let slideViewTopConstraint = slideViewTopConstraint else {
return
}
self.view.addConstraint(slideViewHeightConstraint)
self.view.addConstraint(slideViewTopConstraint)
mainViewHeight = self.view.frame.height
midStateHeight = mainViewHeight/2 - midStateConstant
slideViewHeightConstraint.constant = oneAndHalfMainViewHeight
let maskLayer = CAShapeLayer()
let roundedRect = CGRect(x: 0, y: 0, width: view.bounds.width, height: oneAndHalfMainViewHeight)
maskLayer.frame = roundedRect
maskLayer.path = UIBezierPath(roundedRect: roundedRect, byRoundingCorners: [.topLeft, .topRight], cornerRadii: CGSize(width: 10, height: 10)).cgPath
let frame = CGRect(x: 0, y: 0, width: view.bounds.width, height: oneAndHalfMainViewHeight)
let maskView = UIView(frame: frame)
maskView.layer.addSublayer(maskLayer)
slideView.mask = maskView
當我嘗試在我的iPhone 7它能正常工作,但是, iPhone 7 Plus的模擬器沒有顯示視覺效果,我沒有真正的iPhone 7 Plus來試用它。模擬器顯示了iPhone 5s,SE,6和7的效果。所以我想知道如果我的代碼給出了巨大的尺寸,或者是模擬器上的渲染問題,是否會出現問題。我使用的是2016年的15" 的MacBook Pro,7個加勉強適合在100%的畫面謝謝
注:!這是發生在Xcode中的最新RELASE和Xcode的beta 4版本
更新:我已經能夠嘗試真正的iPhone 6S Plus和工作正常所以肯定一個模擬器圖形問題
