Widgets now include the concept of display mode (represented by 07000),which lets you describe how much content is available and allows users to choose a compact or expanded view.

如何在ios 10.0中扩展小部件？它不像ios 9那样有效.

解决方法

好的,我找到了正确的解决方案 here.

1)首先在viewDidLoad中将显示模式设置为NCWidgetDisplayMode.expanded：

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

2)实施新的协议方法：

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

它将作为官方应用程序.
