CGAffineTransformMakeRotation 和 UIViewController Rotation 困境
我有一个问题。 我有一个 UIImageView，我使用 CGAffineTransformMakeRotation() 对其进行一些旋转。 没问题。 但是当我用 UIViewController 进行旋转时（纵向到横向和/或反向）。 我的 UIImageView 被奇怪地修改了。
它的框架从：CGRectMake(50.f, 50.f, 150.f, 150.f) 变化 到像这样的框架：CGRectMake(50.f, 123.2f, 1004.56f, 1530.456f)
我意识到当我在 UIImageView 上进行旋转时进行 UIViewController 旋转时会发生变化 不等于 0、90、180 或 270
我认为这是因为 UIViewController 更改了 UIImageView 的矩形，但是如何抑制 不幸的是
，我的观点在视觉上发生了变化。 这就是我的问题，也是为什么我在这里谈论这个...... 我谈到了 frame 属性，因为我注意到它发生了奇怪（随机）的变化，即使我在原始 frame 之后更改了它。这个视图似乎并没有“听”它。 我希望我一切都好。 有人寻求解决方案吗？
I've got a problem.
I've an UIImageView and i do some rotation to it with CGAffineTransformMakeRotation().
Not problem with that.
But when i do a rotation with my UIViewController (portrait to landscape and/or inverse).
My UIImageView is modified strangely.
Its frame become change from :CGRectMake(50.f, 50.f, 150.f, 150.f)
to a frame like :CGRectMake(50.f, 123.2f, 1004.56f, 1530.456f)
I realize that changes happens when I do UIViewController rotation when i've done a rotation on my UIImageView not equal to 0, 90, 180, or 270
I think it's because the UIViewController change the rect of the UIImageView but how inhibit
that comportement
Unfortunately my view move/change visually.
That's my problem and why I'm talking about that here...
I spoke about the frame property because I notice it changed strangely (and randomly) and even if I changed it after to my original frame. The view doesn't seem 'listen' to it.
I hope I am well.
Anyone for a solution ?

如果将视图的
transform属性设置为除单位矩阵之外的任何内容（必须执行此操作才能旋转视图），则frame属性将变为未定义，应被忽略。文档中对此进行了说明。仅仅是框架属性出了问题还是视图也在以某种意想不到的方式在视觉上移动/改变？If you set a view's
transformproperty to anything but the identity matrix (which you must have done in order to rotate it), theframeproperty becomes undefined and should be ignored. This is noted in the documentation. Is it just the frame property that goes wrong or is the view moving/changing visually in some unexpected way as well?从您的描述中不清楚，但听起来好像您的
UIImageView是UIViewController拥有的视图的子视图。除非您有理由不以这种方式管理它，否则我建议设置UIImageView支柱和弹簧（即它的autoresizingMask）来显示所需的行为，然后允许父视图来重新定位/调整UIImageView的大小。It's not clear from your description, but it sounds as if your
UIImageViewis a subview of the view owned by yourUIViewController. Unless you have a reason to not manage it this way, I'd suggest setting theUIImageViewstruts and springs (i.e., itsautoresizingMask) to surface the desired behavior and then allow the parent view to reposition/resize theUIImageView.
