-(void)save{
uigraphicsbeginimagecontext(mybackgroundview.bounds.size); //currentview 当前的view
[mybackgroundview.layer renderincontext:uigraphicsgetcurrentcontext()];
uiimage *viewimage = uigraphicsgetimagefromcurrentimagecontext();
uigraphicsendimagecontext();
uiimagewritetosavedphotosalbum(viewimage, nil, nil, nil);
}截取 您想要的一层
uigraphicsbeginimagecontext(cgsizemake(320, 300)); //currentview 当前的view
[self.view.layer renderincontext:uigraphicsgetcurrentcontext()];
uiimage *viewimage = uigraphicsgetimagefromcurrentimagecontext();
uigraphicsendimagecontext();
uiimagewritetosavedphotosalbum(viewimage, nil, nil, nil);
