Today Widget Extension Height - iOS10

问题:

The height for the Today's widget view mode cannot be set for compact Mode. No matter whatever value I set. It sets the height of the widget to a default value. The expanded mode works perfect and the value is properly set and reflected in the widget. I have already added this line in my viewDidLoad() method.

self.extensionContext?.widgetLargestAvailableDisplayMode = .expanded

Here is the code. The value of maxSize cannot be changed too as its a constant.

func widgetActiveDisplayModeDidChange(_ activeDisplayMode: NCWidgetDisplayMode, withMaximumSize maxSize: CGSize) {

        //self.preferredContentSize = (activeDisplayMode == .compact) ? maxSize : CGSize(width: maxSize.width, height: 300)

        if activeDisplayMode == NCWidgetDisplayMode.compact
        {
             self.preferredContentSize = CGSize(width: maxSize.width, height: 300)
        }
        else
        {
            self.preferredContentSize = CGSize(width: maxSize.width, height: 560)
        }
}

回答1:

The height of the widget in iOS 10 is exactly 110 in compact mode. It can be set to whatever height you want in expanded mode, but in compact mode it will always be 110 and that can't be overwritten.

Try to set self.preferredContentSize at viewDidLoad method. Here is full code :

Swift 3

override func viewDidLoad() {

    super.viewDidLoad()

    self.preferredContentSize = CGSize(width:self.view.frame.size.width, height:210)

    if #available(iOSApplicationExtension 10.0, *) {
        self.extensionContext?.widgetLargestAvailableDisplayMode = .expanded
    }
}


 @available(iOS 10.0, *)
    @available(iOSApplicationExtension 10.0, *)
    func widgetActiveDisplayModeDidChange(_ activeDisplayMode: NCWidgetDisplayMode, withMaximumSize maxSize: CGSize) {
        if activeDisplayMode == .expanded {
            self.preferredContentSize = CGSize(width: self.view.frame.size.width, height: CGFloat(3)*self.tableView.rowHeight)
        }else if activeDisplayMode == .compact{
            self.preferredContentSize = CGSize(width: maxSize.width, height: 110)
        }
    }

please use your height for your application. Hope will fix your issue.
