Today Extension: How to work with display mode?


Widgets now include the concept of display mode (represented by NCWidgetDisplayMode), which lets you describe how much content is available and allows users to choose a compact or expanded view.


How to expand widget in ios 10.0? It doesn't work as in ios 9.

Answer

Ok, i found right solution here.

1) Set the display mode to NCWidgetDisplayModeExpanded first in viewDidLoad:

override func viewDidLoad() {
    super.viewDidLoad()
    self.extensionContext?.widgetLargestAvailableDisplayMode = NCWidgetDisplayMode.Expanded
}

2) Implement new protocol method:

func widgetActiveDisplayModeDidChange(_ activeDisplayMode: NCWidgetDisplayMode, withMaximumSize maxSize: CGSize) {
    if (activeDisplayMode == NCWidgetDisplayMode.compact) {
        self.preferredContentSize = maxSize
    }
    else {
        self.preferredContentSize = CGSize(width: maxSize.width, height: 200)
    }
}

And it will work as official apps.
