ios - If my UIView is set be opaque, why is it still being colored as "blended" by the simulator? -


i have uilabel @ initialization set opaque (opaque = yes), , if use "debug view hierarchy" button preview views @ runtime, can see indeed set opaque expect.

however if turn on color blended layers in ios simulator, same view red, indicated blended, performance reasons don't want.

why this? doing wrong? why still blended?

a view not opaque (even if set opaque = yes) compositing unless has opaque backgroundcolor.
