ios - UIToolbar not transparent on iPad2 -


this has been driving me nuts.

i have toolbar on ipad application , translucent property set 'yes'. doing in storyboard:

enter image description here

when run on ipad air things good. if run on ipad 2 toolbar not translucent. experience same problem in simulator , on actual device.

this not problem across different versions of os. ie no matter os run (ios 7 or ios 8) wrong on ipad 2 correct on ipad air.

why????

is there can consistent l&f across these devices?

translucency - uses blur - computationally expensive.

if compare control panel or notification menu between ipad 2 , ipad air, - see apple has disabled translucency on lower powered device can't cope.

that applies ipad2, ipad3, ipad mini , maybe older iphones , ipod touches. higher-powered devices can give poor results if over-use these effects.

if need consistent , feel, should resist using properties take advantage of translucency , blur effects. option play around view alpha, background colour , tint semi-tranparent on devices don't support translucency.

for more information on device support uivisualeffect, seems coincide 'translucency' property support on ui objects:

check if device supports blur
detect if device displays uivisualeffectview?
