UIPopoverController - 位于缩放/滚动视图内的presentPopoverFromRect？
我有一个缩放/滚动 UIScrollview，我可以在上面放置视图（想想绘图对象、圆形、正方形等），我在上面放置一个正方形，然后点击并按住，出现菜单，然后我选择属性。我传入 Rect 的 square.frame，弹出框看起来很棒，适合 UIScrollView。
现在我缩放 UIScrollView ，使 Square 大于屏幕上的可见区域。点击并按住，选择属性，弹出窗口就会显示在某处，尽管不是我能看到的任何地方。
我不知道如何从 Square 的角度检测它是否大于 super.view 放大区域的可见区域，并从不同的 Rect 呈现 Popover。
缩小，正方形完全可见，并且在画布上有弹出窗口的空间
self.frame: {{0, 659.959}, {1846.72, 1388.04}}
self.superview.frame: {{0, 0}, {1024, 1024}}
self.superview.superview.frame: {{0, 44}, {1024, 704}}
self.superview.superview.superview.frame:{{0, 0}, {1024, 748}}
放大，正方形覆盖整个屏幕
self.frame: {{0, 659.959}, {1846.72, 1388.04}}
self.superview.frame: {{0, 0}, {3180.31, 3180.31}}
self.superview.superview.frame: {{0, 44}, {1024, 704}}
self.superview.superview.superview.frame:{{0, 0}, {1024, 748}}
最大缩放，虽然滚动，所以画布上有弹出窗口的空间
self.frame: {{0, 659.96}, {1822.62, 1369.96}}
self.superview.frame: {{0, 0}, {4096, 4096}}
self.superview.superview.frame: {{0, 44}, {1024, 704}}
self.superview.superview.superview.frame:{{0, 0}, {1024, 748}}
最后一个脚趾似乎没有区别告诉我们该正方形覆盖了屏幕，而不是只有一小部分可见。
欢迎任何建议！
I have a scaling/scrolling UIScrollview that I can place views on (think Drawing objets, Circles, squares, etc) I place a square on there and tap and Hold, menu comes up and I select Properties. I pass in the square.frame for the Rect and the popover looks great where it can fit in the UIScrollView.
Now I scale the UIScrollView so that the Square is bigger than the visible area on the screen. Tap and Hold, select properties, and the Popover is Presented somewhere, though not anywhere I can see.
I'm not sure how to detect from the Square's perspective if its bigger than the visible area of the super.view's zoomed in area and present the Popover from a different Rect.
Zoomed Out, square is completely visible and has room for popover on canvas
self.frame: {{0, 659.959}, {1846.72, 1388.04}}
self.superview.frame: {{0, 0}, {1024, 1024}}
self.superview.superview.frame: {{0, 44}, {1024, 704}}
self.superview.superview.superview.frame:{{0, 0}, {1024, 748}}
Zoomed In, square is covering all of screen
self.frame: {{0, 659.959}, {1846.72, 1388.04}}
self.superview.frame: {{0, 0}, {3180.31, 3180.31}}
self.superview.superview.frame: {{0, 44}, {1024, 704}}
self.superview.superview.superview.frame:{{0, 0}, {1024, 748}}
Max Zoom, though scrolled so there is room for popover on canvas
self.frame: {{0, 659.96}, {1822.62, 1369.96}}
self.superview.frame: {{0, 0}, {4096, 4096}}
self.superview.superview.frame: {{0, 44}, {1024, 704}}
self.superview.superview.superview.frame:{{0, 0}, {1024, 748}}
There does not seem to be a difference in the last toe to really tell that the square is coving the screen vs only a smidgin of it visible.
Any Suggestions welcome!

这取决于弹出窗口控制器正在显示哪个视图，但您可以尝试使用以下命令将 Squares 框架从滚动视图转换为显示弹出窗口的视图
it depends on which view the popover controller is being displayed, but you could try converting the Squares frame from the scrollview to the view displaying the popover using
