Get Current Directory in Objective-C
Since Mac OS X is a unix based system, you can always use “getcwd” from the standard C library, but in general if you want to stick within the context of Objective-C/Cocoa, see the examples below.
Here’s one snippet you will probably Google quickly, but ultimately not the solution I chose.
(original code from stackoverflow see reference below)
NSFileManager *filemgr; NSString *currentpath; filemgr = [[NSFileManager alloc] init]; currentpath = [filemgr currentDirectoryPath];
Solution
Using the “bundle path” rather than “executable path” turned out to work much better in my instance:
NSString *currentpath = [[[[NSBundle mainBundle] bundlePath] stringByDeletingPathExtension] stringByDeletingLastPathcomponent]; NSString *fileName = [NSString stringWithFormat:@"%@/%@/",currentpath,@"filename.pdf"];

Concatenate string in Objective-C
Unfortunately, this is not as straight forward as it seems it should be. This really comes down to roughly two approaches in my opinion:
stringByAppendingString approach:
NSString *robot= @"Ronnie"; NSString *robotname = [robot stringByAppendingString:@" is the name of a robot."];
strigWithFormat approach:
NSString *robot= @"Ronnie"; NSString *robotname= @" is the name of the a robot."; NSString *robotknowledge = @" knows eight languages."; [NSString stringWithFormat:@"%@/%@/%@", robot, robotname, robot, robotknowledge];
