原文 2016-10-16 19:59:25 1 2 ios/ xcode/ storyboard/ launch

I set up a Launch Screen in xcode with Inferred Size, Simulated Size: Fixed. 我在xcode中用推断的大小，模拟的大小设置了启动屏幕：固定。 I put a View in it that covers the whole View Controller. 我在其中放置了一个涵盖整个View Controller的View。 In that View is an image and a label. 在该视图中是图像和标签。 Both the image and label have height and width constraints, in addition to constraints centering both items with the superview center, yet somehow whenever I run the simulation the label is centered on the screen but the image is off to the right. 图像和标签都具有高度和宽度约束，除了将两个项目都以超级视图中心居中的约束之外，无论如何，无论何时我运行模拟，标签都位于屏幕的中心，但是图像位于右侧。 Anyone know what I need to fix here? 有人知道我需要在这里解决吗？ Thanks! 谢谢！

Edit: It turns out I had a previous launch screen file listed in Info.plist. 编辑：原来我在Info.plist中列出了以前的启动屏幕文件。 I updated it with the new launch screen file name and it worked. 我使用新的启动屏幕文件名对其进行了更新，并且可以正常工作。 I also changed the launch screen to remove the splash. 我还更改了启动屏幕以删除启动画面。

2 个解决方案

Use width and height equal to, and align your view horizontally in the container.. 使用宽度和高度等于的高度，并在容器中水平对齐视图。

Also, as per Apple's human guidelines they advise against having a splash screen. 另外，根据Apple的人工指导，他们建议不要使用启动屏幕。

Workaround of this issue is to not place image vertically centered. 此问题的解决方法是不要将图像垂直居中放置。 You can move image a bit to top or bottom. 您可以将图像稍微移到顶部或底部。 In such way issue won't be visible. 这样，问题将不可见。
