Xcode is not showing my buttons, labels, textfields, and views
提问by idelara
Xcode is not showing all the buttons, textfields, etc. I have in my storyboard. As you can see in the image below, somehow all my elements are appearing with a "watermark" in the storyboard element inspector on the left. Why is it doing this? How can I fix it? It is driving me crazy because I cannot see where my elements are when I try and add some more...
Xcode 没有显示我的故事板中的所有按钮、文本字段等。正如您在下图中所看到的，不知何故，我的所有元素都在左侧的故事板元素检查器中出现了“水印”。为什么要这样做？我该如何解决？这让我发疯了，因为当我尝试添加更多元素时，我看不到我的元素在哪里......
How can I solve this and why is Xcode so buggy anyways?
我该如何解决这个问题，以及为什么 Xcode 如此有问题？

You have a size class enabled (note the blue bar across the center-bottomish). My guess is that all those views are missing in that size class. Click the bar, turn it back to Any x Any.
您启用了尺寸等级（注意中间底部的蓝色条）。我的猜测是该尺寸等级中缺少所有这些视图。单击该栏，将其转回 Any x Any。

I had a similar problem, some of my IBOutlets (labels) were showing on the Storyboard, I had no AutoLayout warnings/errors and everything seemed fine but yet some of the outlets were not showing on the Simulator. Things got even more complicated when I noticed that SOMETIMES the outlets DID show.. strange..
我有一个类似的问题，我的一些 IBOutlets（标签）显示在 Storyboard 上，我没有 AutoLayout 警告/错误，一切似乎都很好，但有些插座没有显示在模拟器上。当我注意到有时网点确实显示..奇怪..时，事情变得更加复杂。
I ended up wrapping the call to show the view controller in a GCD method like this (swift code):
我最终将调用包装起来以在这样的 GCD 方法中显示视图控制器（swift 代码）：
dispatch_async(dispatch_get_main_queue()) {
[unowned self] in
let vc = self.pages[0]
self.setViewControllers([vc], direction: .Forward, animated: false, completion: nil)
}
And that solved it..
这解决了它..
