切换视图时保持 xcode 中的滑块位置 [英] maintaining slider position in xcode when switching views

问题描述

我对目标 c 非常陌生(三周)，而且我已经 70 多岁了，所以不像以前那么快！无论如何，除了在切换视图并再次切换时保持滑块位置和值的问题外，我对 IOS 的应用程序做得很好.澄清一下:我有 3 个视图，每个视图有 4 个滑块，我希望能够返回到任何视图，滑块的位置和值与它们离开时相同.我确定有一种方法可以做到这一点，但我到处搜索都无济于事，所以我希望这里有人可以提供帮助！

I'm very new to objective c (three weeks) and also in my 70s so not as quick as I used to be! Anyway, I'm doing okay with an app for IOS except for a problem with maintaining slider position and value when switching away from a view and back again. To clarify: I have 3 views, each with 4 sliders and I want to be able to return to any view with the sliders positions and values the same as they were left. I'm sure there's a way of doing this but I've searched all over to no avail so I hope someone here can help!
