iOS 8今日扩展中的适合宽度 [英] Fit width in iOS 8 Today Extensions

问题描述

当我制作任何iOS 8 Today Extension时，左边有一个大约48px的空白区域，即使在Interface Builder中我在x = 0左侧放置了一个标签。

When I make any iOS 8 Today Extension, there is an empty space on the left of approximately 48px, even if in Interface Builder I place a label on the left side at x=0.

我已经看到一些应用程序使用全宽小部件。

I have seen that some apps, however, use a full-width widget.

我如何实现类似的目标？

How can I achieve something similar?

谢谢！

更新：已解决

我在这里放了示例代码，因为我猜这对某人有用。正如@ matteo-lallone所建议的那样，正确的方法是：

I put here the sample code because I guess it will be useful to someone. As suggested by @matteo-lallone, the correct way to do this is:

-(UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets)defaultMa‌​rginInsets{
return UIEdgeInsetsZero;
}

推荐答案

直接从文档：

使用Xcode Today模板创建的今日小部件包括Auto
标准边距插入的布局约束。要获得计算的插入值
，请实现
widgetMarginInsetsForProposedMarginInsets：方法。

A Today widget created using the Xcode Today template includes Auto Layout constraints for standard margin insets. To get the inset values for your calculations, implement the widgetMarginInsetsForProposedMarginInsets: method.
