xcode - How to write NSString with .jpg for all strings? -

i new in programming , know how can write nsstring .jpg extension.

i have code viewcontroller has title , title use nsstring. use string find image same name. dont know configure .jpg extension.

here code:

- (void)viewdidload{      [super viewdidload];     nsstring*imagename = [nsstring stringwithformat:(@"% .jpg", self.title)];     uiimage*image = [uiimage imagenamed:imagename];     [imageview setimage:image];    nslog(@"%", imagename); } 

funny nslog line don't work. can problem in prepareforsegue method?:

-(void)prepareforsegue:(uistoryboardsegue *)segue sender:(id)sender{      if ([segue.identifier isequaltostring:@"cell segue"]) {      imageshowingviewcontroller*ivc = segue.destinationviewcontroller;      ivc.title = [self.objects objectatindex:(self.tableview.indexpathforselectedrow.row)];    } } 

when push cell in tableviewcontroller push segue activated , show second viewcontroller. part of code works fine no nslog line there if viewdidload finished. when on breakpoint on start viewdidload method , on nslog line show me
"imagename __nscfstring * @"bread" 0x00000001095515f0

any appreciated.

problem solved. should [nsstring stringwithformat:@"%@", self.title] , not [nsstring stringwithformat:(@"%@", self.title)]

use

nsstring *imagename = [nsstring stringwithformat:@"%@.jpg", self.title]; uiimage*image = [uiimage imagenamed:imagename]; [_image setimage:image]; 

stringwithformat: should used instead of stringwithstring:. also, parenthesis shouldn't used in expression.

also, not clear [image setimage:image]; supposed do. first image image view? i've updated answer distinct loaded image, you'll need determine value should be.
