objective c - How to take my view as a picture osx -

i want take nsview(with layers) image can in osx ?

in ios following

-(uiimage*) makeimage//snapshot view {     uigraphicsbeginimagecontext(self.view.bounds.size);     [self.view.layer renderincontext:uigraphicsgetcurrentcontext()];     uiimage *viewimage = uigraphicsgetimagefromcurrentimagecontext();     uigraphicsendimagecontext();     return viewimage; } 

i tried solution 1 of answers

[[nsimage alloc] initwithdata:[view datawithpdfinsiderect:[view bounds]]]; 

but didn't work because have layers in nsview.

i started converting ui ns , have warnings on every line :)

-(nsimage*) makeimage :(rmblurredview*)view {     uigraphicsbeginimagecontext(view.bounds.size);      [self.view.layer renderincontext:uigraphicsgetcurrentcontext()];      nsimage *viewimage = uigraphicsgetimagefromcurrentimagecontext();      uigraphicsendimagecontext();      return viewimage; } 

i not familiar osx can 1 me convert code osx ?

drawing image tad different in ios:

1. you create blank image, lock on it, drawing goes graphics context

   nsimage *image = [[nsimage alloc] initwithsize:self.view.bounds.size]; [image lockfocus]; 

2. you draw layer same on ios

   cgcontextref ctx = [nsgraphicscontext currentcontext].graphicsport; [self.view.layer renderincontext:ctx]; 

3. unlock image

   [image unlockfocus]; 

note if view layered. doesn't work non-layered views!
view -as shown above- layer backed all's fine ;)
