Re: CALayer contentScale initialization, where to do it?
contentsScale won't matter until you the layer into a window, so why not just assign it when you add the layer as a sublayer? -- David Duncan @ My iPhone On Jun 16, 2012, at 10:57 PM, Markus Spoettl ms_li...@shiftoption.com wrote: On 6/16/12 11:59 PM, Kyle Sluder wrote: That's the same document I was referring to.

Re: CALayer contentScale initialization, where to do it? (SOLVED)
On 6/17/12 9:15 AM, David Duncan wrote: contentsScale won't matter until you the layer into a window, so why not just assign it when you add the layer as a sublayer? Turns out that my problem was caused by the time the NSView's root layer was set up: In previous AppKit versions, NSView's -setLayer: -wantsLayer: needed to be outside of -initWithFrame: because for whatever reason, setting it up in -initWithFrame: didn't work (it simply was reset). On Lion this seems to have been fixed - which I didn't realize before - and the contentsScale of the root layer and its sub-layers is set by the framework automatically during view initialization/nib loading. So problem solved, thanks guys! Regards Markus -- __ Markus Spoettl ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: CALayer contentScale initialization, where to do it?
Same concept applies. Set it when you assign the layer or add the view. -- David Duncan @ My iPhone On Jun 17, 2012, at 12:55 AM, Markus Spoettl ms_li...@shiftoption.com wrote: On 6/17/12 9:15 AM, David Duncan wrote: contentsScale won't matter until you the layer into a window, so why not just assign it when you add the layer as a sublayer?

I don't recall reading about avoiding backingScaleFactor, though.
