Question

Was zwischen widgetSecondaryVibrancyEffect und widgetPrimaryVibrancyEffect anders?

Answer 1

widgetPrimaryVibrancyEffect

Für die Verwendung mit ausgewählten Begleittext und Glyphen.

widgetSecondaryVibrancyEffect

Für die Verwendung mit ausgewählten Begleittext und Glyphen, wo eine weitere Verminderung

hier erforderlich ist, ist eine Darstellung mit zwei UIButtons:

Swift 3.0 TodayViewController (Heute Extension):

import UIKit 
import NotificationCenter 

class TodayViewController: UIViewController, NCWidgetProviding { 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view from its nib. 
     self.extensionContext?.widgetLargestAvailableDisplayMode = .expanded 

     setupStackView() 
    } 
    private func setupStackView(){ 
     let stackView = UIStackView(frame: CGRect.zero) 
     stackView.translatesAutoresizingMaskIntoConstraints = false 
     stackView.alignment = .fill 
     stackView.axis  = .vertical 
     stackView.distribution = .fillEqually 

     self.view.addSubview(stackView) 

     let hConstraints = NSLayoutConstraint.constraints(withVisualFormat: "H:|[stackView]|", options: NSLayoutFormatOptions(rawValue:0), metrics: nil, views: ["stackView":stackView]) 
     let vConstraints = NSLayoutConstraint.constraints(withVisualFormat: "V:|[stackView]|", options: NSLayoutFormatOptions(rawValue:0), metrics: nil, views: ["stackView":stackView]) 

     self.view.addConstraints(hConstraints) 
     self.view.addConstraints(vConstraints) 


     stackView.addArrangedSubview(self.effectView(withEffect: UIVibrancyEffect.widgetPrimary(), andButtonTitle: "widgetPrimaryVibrancyEffect")) 
     stackView.addArrangedSubview(self.effectView(withEffect: UIVibrancyEffect.widgetSecondary(), andButtonTitle: "widgetSecondaryVibrancyEffect")) 
    } 

    private func effectView(withEffect effect : UIVisualEffect, andButtonTitle title : String)->UIVisualEffectView{ 
     //Create button 
     let button = UIButton(type: .custom) 
     button.translatesAutoresizingMaskIntoConstraints = false 
     button.setTitle(title, for: .normal) 

     //Create UIVisualEffectView 
     let effectView = UIVisualEffectView(effect: effect) 
     effectView.frame = CGRect.zero 
     effectView.translatesAutoresizingMaskIntoConstraints = false 


     effectView.contentView.addSubview(button) 

     //Constraints 
     button.leftAnchor.constraint(equalTo: effectView.contentView.leftAnchor).isActive = true 
     button.topAnchor.constraint(equalTo: effectView.contentView.topAnchor).isActive = true 
     button.rightAnchor.constraint(equalTo: effectView.contentView.rightAnchor).isActive = true 
     button.bottomAnchor.constraint(equalTo: effectView.contentView.bottomAnchor).isActive = true 

     return effectView 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
    } 

    func widgetPerformUpdate(completionHandler: ((NCUpdateResult) -> Void)) { 
     completionHandler(NCUpdateResult.newData) 
    } 

}
