UIScrollView边界尚未在“viewDidLoad”中调整大小。 [英] UIScrollView bounds have not yet resized in "viewDidLoad"

问题描述

我有一个UIViewController子类，其视图在NIB文件中配置。该视图有一个UIScrollView子视图。

UIScrollView几乎占用了整个NIB文件，但它的superview作为子视图添加到一个更小的视图（配置在不同的NIB ） - 例如UIScrollView是它自己的NIB的高度的80％，但最终只有应用程序的窗口的高度的10％。

当我调用[scrollView bounds] .size。 height在viewController的viewDidLoad方法中，我得到了scrollView相对于它自己的NIB的高度，而不是它的高度，它调整大小到它的superviews指定的（例如窗口的高度的80％，而不是10％）。 p>

如果我稍后调用[scrollView bounds] .size.height（例如处理旋转事件），我得到正确的值。

如何获得最初正确调整大小的值？

解决方案

viewWillAppear：或 viewDidAppear ？

I have a UIViewController subclass whose view is configured in a NIB file. The view has a UIScrollView subview.

The UIScrollView takes up almost its entire NIB file but it's superview is added as a subview to a much smaller view (configured in a different NIB) - e.g. the UIScrollView is 80% the height of it's own NIB but ends up only being 10% the height of the application's window.

When I call [scrollView bounds].size.height in the viewController's viewDidLoad method, I get the height of the scrollView relative to it's own NIB, rather than the height it ends up resizing to as dictated by its superviews (e.g. 80% of the window's height rather than 10%).

If I call [scrollView bounds].size.height later on (e.g. to handle a rotation event), I get the correct value.

How can I get the correctly re-sized value initially?

解决方案

Have you tried dealing with it in viewWillAppear: or viewDidAppear?
