Question

I’m trying to make an SDL application in Xcode, but I’m having trouble loading images. I’m using this template, because I couldn’t get it to work when made from scratch.

Whenever I try to load an image with SDL_LoadBMP however, it returns NULL unless I give the absolute path. (/Users/Cole/code…) I looked in the exported .app file, and it does have the image I want to load in Contents/Resources/, and I’ve tried every combination I can think of to get at those (../Resources/image.bmp, ect.) but I can’t seem to get it working.

Does anyone have a solution? I’m running Mac OS 10.7 with Xcode 4, so I can’t use the templates that is within the SDL download.

Also, I tried using SDL_ttf, but I get this error:

warning: Unable to read symbols for @executable_path/../Frameworks/SDL_ttf.framework/Versions/A/SDL_ttf (file not found).
warning: Unable to read symbols from "SDL_ttf" (not yet mapped into memory).

There does not happen to be a Frameworks folder where it’s looking, but somehow it finds the regular SDL framework just fine.

Answer 1

You can get the path to your the Resources directory containing your file with

NSString *path = [[NSBundle mainBundle] resourcePath];

or alternatively (in theory more clean as it can access localized files) you can get the full file name with

NSString *file = [[NSBundle mainBundle] pathForResource:@"image.bmp" ofType:nil];

You’ll need to pass the C string to SDL_LoadBMP, so either of the two:

SDL_LoadBMP([[path stringByAppendingString: @"/image.bmp"] UTF8String]);

SDL_LoadBMP([file UTF8String]);
