just tested this, create context based on sizes of images working , draw them on top of each other (this assumes same width):

uiimage *image1 = [uiimage imagenamed:@"image1.png"]; uiimage *image2 = [uiimage imagenamed:@"image2.png"];  cgsize size = cgsizemake(image1.size.width, image1.size.height + image2.size.height);  uigraphicsbeginimagecontext(size);  [image1 drawinrect:cgrectmake(0,0,size.width, image1.size.height)]; [image2 drawinrect:cgrectmake(0,image1.size.height,size.width, image2.size.height)];  uiimage *finalimage = uigraphicsgetimagefromcurrentimagecontext();  uigraphicsendimagecontext();  //add image view uiimageview *imageview = [[uiimageview alloc] initwithframe:cgrectmake(0, 0, finalimage.size.width, finalimage.size.height)]; imageview.image = finalimage; [self.view addsubview:imageview];

assembly - 8086 TASM: Illegal Indexing Mode -
