nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes); nsstring *documentsdirectory = [paths objectatindex:0]; nstimeinterval timeinmiliseconds = [[nsdate date] timeintervalsince1970]; nsstring *generatedstring = [nsstring stringwithformat:@"background%f.png", timeinmiliseconds]; nsstring *pngpath = [documentsdirectory stringbyappendingpathcomponent:generatedstring]; [uiimagepngrepresentation(custombackground) writetofile:pngpath atomically:yes];
i saving pngpath plist above using string in this:
uiimage *image = [uiimage imagewithcontentsoffile:string];
