[英]Xcode auto layout constraints - why defaulting to negative padding?
I am simply adding a UIView into the main view of a view controller. 我只是将UIView添加到视图控制器的主视图中。 I want the height to always be 64px, but the width to stretch to the width of the screen.
我希望高度始终为64px,但宽度要拉伸到屏幕的宽度。
However, when I go to add constraints, the left and right padding default to -16, even though the view is stretched all the way across its parent view. 但是,当我去添加约束时,左边和右边的填充默认为-16,即使视图在其父视图中一直延伸。 Even if I set these back to 0, when I run the app the -16 padding is added back in. What is going on here?
即使我将它们设置为0,当我运行应用程序时,会重新添加-16填充。这里发生了什么?
取消选中pin菜单中的“Constrain to margins”复选框 (问题中的第一个图像),同时为新约束添加间隔到最近邻居 。
