Today Extension: 如何使用显示模式？

Question

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.

如何在 ios 10.0 中扩展小部件？它不像 ios 9.

那样工作

Answer 1

好的，我找到了正确的解决方案 here。

1)先在viewDidLoad中设置显示模式为NCWidgetDisplayMode.expanded:

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

2) 实现新的协议方法：

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运行。

这是一个Objective-C。

- (void)widgetActiveDisplayModeDidChange:(NCWidgetDisplayMode)activeDisplayMode
                         withMaximumSize:(CGSize)maxSize
{
    if (activeDisplayMode == NCWidgetDisplayModeCompact) {
        self.preferredContentSize = maxSize;
    }
    else {
        self.preferredContentSize = CGSizeMake(0, 200);
    }
}
