the sun in image problem i'm speaking of. ideas?

on-the-fly image resizing quick , of low quality. bundled images, worth bundle space include downsized versions. downloaded images, can achieve better results resizing core graphics new uiimage before set image property.

cgsize newsize = cgsizemake(newwidth, newheight);  uigraphicsbeginimagecontextwithoptions(newsize, // context size                                        no,      // opaque?                                        0);      // image scale. 0 means "device screen scale" cgcontextref context = uigraphicsgetcurrentcontext();  cgcontextsetinterpolationquality(context, kcginterpolationhigh); [bigimage drawinrect:cgrectmake(0, 0, newsize.width, newsize.height)]; uiimage *newimage = uigraphicsgetimagefromcurrentimagecontext(); uigraphicsendimagecontext();
