设置横向模式下popover的高度

Question

我想修改横向模式下popover的高度，但它只能在纵向模式下工作。

我希望它的高度等于screenSize.height * 0.7，但它不适用于我的代码下面。

这里是我的代码：

if let orientation = UIDevice.current.value(forKey: "orientation") as? Int { 
     let diamondViewController = DiamondViewController() 
     diamondViewController.mode = .buyDiamondPopup 
     diamondViewController.resetBackgroundColor = { 
      self.view.backgroundColor = .clear 
     } 

     let screenSize = UIScreen.main.bounds 
     if orientation == 3 { // LandscapeRight 
      diamondViewController.preferredContentSize = CGSize(width: screenSize.width * 0.6, height: 
       screenSize.height * 0.7) 
     } else { 
      diamondViewController.preferredContentSize = CGSize(width: screenSize.width - 60, height: 
       min(screenSize.height - 180, CGFloat(5 * 70 + 110))) 
     } 
     diamondViewController.modalPresentationStyle = .popover 
     if let popover = diamondViewController.popoverPresentationController { 
      popover.permittedArrowDirections = .init(rawValue: 0) 
      popover.sourceView = self.view 
      popover.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0) 
      popover.delegate = self 
      self.view.backgroundColor = UIColor.black.withAlphaComponent(0.5) 
      self.present(diamondViewController, animated: true, completion: nil) 
     } 
    } 

...

func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle { 
    return .none 
} 

Answer 1

这

diamondViewController.preferredContentSize = CGSize(width: screenSize.width * 0.6, height: screenSize.height * 0.7) 

相反试试这个下面

diamondViewController.view = CGRect(x: diamondViewController.view.frame.origin.x ,y: diamondViewController.view.frame.origin.y ,width: screenSize.width * 0.6, height: screenSize.height * 0.7) 

如果它没有帮助，那么让我知道。

您是否尝试过使用“Vary for traits”工具？它允许您根据设备方向应用不同的约束条件。可以在故事板右下角靠近不同约束选项的位置找到它。
