how to convert a selected image from iphone library to pdf in ios sdk -

now using code. pdf generating image not displaying.

-(void)imagepickercontroller:(uiimagepickercontroller *)pickerdidfinishpickingmediawithinfo:(nsdictionary *)info {     nslog(@"%@",info);         //selectedimage =  [info objectforkey:uiimagepickercontrolleroriginalimage];             uiimage *image=[info objectforkey:uiimagepickercontrolleroriginalimage];             nslog(@" selected image - %@",image);     imagestr=[nsstring stringwithformat:@"%@",image];      nsarray *paths = nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes);      nsstring *documentsdirectory = [paths objectatindex:0];      nsstring *localfilepath=[documentsdirectory stringbyappendingpathcomponent:@"images.pdf"];     nslog(@"file path %@",localfilepath);     [self pdfgenerate:localfilepath];     uigraphicsendpdfcontext();     [imagepicker dismissviewcontrolleranimated:yes completion:nil]; }  -(void)pdfgenerate:(nsstring *)filepath {     uigraphicsbeginpdfcontexttofile(filepath, cgrectzero, nil);     uigraphicsbeginpdfpagewithinfo(cgrectmake(0, 0, 300, 300), nil);     [self convertimagetopdf]; }  -(void)convertimagetopdf {     cgrect imagerect=cgrectmake(0, 0, 300, 300);     nslog(@"image  %@",imagestr);     uiimage *image=[uiimage imagenamed:imagestr];     [image drawinrect:imagerect]; } 

you saving selected image in nsstring object imagestr (imagestr=[nsstring stringwithformat:@"%@",image];)

so when creating image inside convertimagetopdf method (uiimage *image=[uiimage imagenamed:imagestr];), image object nil. pdf blank.

instead can have uiimage reference image picked picker. use reference inside convertimagetopdf draw.

update code:

inside didfinishpickingmediawithinfo

pickedimage=[info objectforkey:uiimagepickercontrolleroriginalimage];         

inside convertimagetopdf

cgrect imagerect=cgrectmake(0, 0, 300, 300); [pickedimage drawinrect:imagerect]; 

pickedimage object of type uiimage.
