ios - Save UIImageView image -


i have ability take photo or load camera , place image in uiimageview in app want ability have button save image when reload app image still in uiimageview.

my though button save image once have loaded , in 

-(void)viewdidload

have code load image saved don't know how approach this.

any fantastic.

you can convert images nsdata using either uiimagepngrepresentation or uiimagejpgrepresentation, save data file calling 1 of nsdata's writetofile... methods.

then when restart application, can image calling [uiimage imagewithdata:[nsdata datawithcontentsoffile:filepath]]

-- edit --

save image

uiimage *image = ...; nsstring *cachedfolderpath = nssearchpathfordirectoriesindomains(nscachesdirectory, nsuserdomainmask, yes)[0]; nsstring *cachedimagepath = [cachedfolderpath stringbyappendingpathcomponent:@"image.png"]; [uiimagepngrepresentation(image) writetofile:cachedimagepath atomically:yes];

load image

nsstring *cachedfolderpath = nssearchpathfordirectoriesindomains(nscachesdirectory, nsuserdomainmask, yes)[0]; nsstring *cachedimagepath = [cachedfolderpath stringbyappendingpathcomponent:@"image.png"]; uiimage *image = [uiimage imagewithdata:[nsdata datawithcontentsoffile:cachedimagepath]];

i used nscachesdirectory since i'm assuming don't want have image backed (either through icloud or itunes). if you'd want use nsdocumentdirectory instead.

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
