我无法满足今天 IOS 8 扩展中的限制

【中文标题】我无法满足今天 IOS 8 扩展中的限制

【英文标题】：I am unable to satisfy the constraints in the IOS 8 today extension

【问题描述】：

我几乎放弃了在今天的扩展中解决自动布局问题:-(。

我的 ios 8 应用有一个简单的 Today 扩展，我想在其中显示一张二次照片和两个文本标签。

感谢您的帮助。

这是我的实际布局。该视图在模拟器和我的真 iPhone 上几乎可以正确显示，但我无法消除自动布局错误消息。

Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

将尝试通过打破约束来恢复

【参考方案1】：

Apple 方面存在一个错误，即今天扩展的自动布局。我的自动布局约束实际上为零，它已关闭，但我仍然得到“无法同时满足约束”。
