ios - "Renders with edge antialiasing" Makes UIViews look worse with transform -

-

i have uiviews have transform both translation , rotation , looking aliased turned on "renders edge antialiasing" in -info.plist , makes worse!

instead of being jaggy, seem have black mixed in jaggy edges. there shadow, layer behind not black.

is there i'm missing here?

i found lot of different advice on this, seems "renders edge antialiasing" doesn't lot in grand scheme of things. however, helps little solution found below:

self.layer.shouldrasterize = yes; self.layer.rasterizationscale = [[uiscreen mainscreen] scale];

these 2 lines go on uiview gets transformed layer [uicolor clearcolor] background. colors or images or content subview. otherwise, rounded corners i'm using, saw little black on edges.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
