ios - In Xcode Interface Builder - why are the options in the Editor--->Arrange menu (containing Send to Front, Send to Back) often disabled? -

-

what i'm trying simple: bring label in front of image within subview.

but of options arranging disabled/un-selectable when label selected. find happens often.

what reason i'm never allowed change z-axis of objects in arrange menu? better practice avoid feature , set order of views programmatically?

it can depend on how have selected label (similar how label can moved keyboard when selected in ways).

a simple alternative @ list of view in pane on left , drag views , down change order.
