当我的应用程序启动时,我的视图边界的 NSLog 显示以下内容:
NSLog(@"My view frame: %@", NSStringFromCGRect(self.view.bounds));
My view frame: {{0, 0}, {320, 548}}
然后我旋转模拟器并得到以下信息:
NSLog(@"My view frame: %@", NSStringFromCGRect(self.view.bounds));
My view frame: {{0, 0}, {320, 548}}
然后当我将模拟器旋转回肖像时,我得到了这个:
NSLog(@"My view frame: %@", NSStringFromCGRect(self.view.bounds));
My view frame: {{0, 0}, {568, 300}}
我用来调整元素的两种方法是这些,它们还没有完成,因为我目前正在为新 iPhone 修复它们。

我的头快要爆炸了。不仅视图被颠倒了,而且从宽度上抢走了 20 个像素并赋予了高度。任何人都可以向我解释这一点,以及我如何/应该在我的视图中对元素进行编码以解释它吗?
我的故事板如下:

我的初步看法:

第一次旋转后(仍然很好)

旋转回纵向(由于边界值而全部搞砸了)
