I am trying to develop a simple app with one screen for iOS and am running into a strange problem. Only half of the app is showing up. For example I have a screen with just one button in the center of the screen. When I run the app in the simulator I only see half the button and I cannot move it either.I can scroll the view in the simulator vertically but not horizontally. I am stumped. Will appreciate any pointers.

推荐答案

我很确定您使用主故事板构建了视图，并将所有内容放在其中.主故事板设置为将所有iOS格式(iPhone和iPad)都考虑在内.如果希望您的应用程序显示在iOS设备上的中心位置，则需要使用自动布局"来限制不同UI对象的位置.这样，无论您使用什么设备，它都会自动居中显示

I'm pretty sure you built your view using the main storyboard and put everything in the middle of it. The main storyboard is set to take all iOS format into account, iPhone and iPad. If you want your app to appear centered on your iOS device, you need to constraint the position of your different UI objects, using Auto Layout. That way it would appear centered automatically, whatever is the device you're using
