It’s recommended practice to treat build warnings the same as errors so here’s a handy little tidbit to help you out:
The deprecated way:
NSArray *fileList = [manager directoryContentsAtPath:productDirectory];
replace directoryContentsAtPath with contentsOfDirectoryAtPath & you must also add error:nil
The new hotness:
NSArray *fileList = [manager contentsOfDirectoryAtPath:productDirectory error:nil];
Now that I’ve started working with the latest and greatest iPhone SDK I’m running into a bunch of deprecated method errors. It’s recommended practice to treat warnings the same as errors so I have been trying to fix them as they pop up. The one in particular that was giving me trouble today was:
NSString *contents = [NSString stringWithContentsOfFile:fullpath];
After doing a bit of Googling I found the solution.
Replace NSString *contents = [NSString stringWithContentsOfFile:fullpath]; with:
NSString *contents = [NSString stringWithContentsOfFile:fullpath encoding:NSUTF8StringEncoding error:nil];[NSString stringWithContentsOfFile:fullpath encoding:NSUTF8StringEncoding error:nil];
(Side Note: Ever since I began coding my vocabulary has expanded. Now I get to use words like Redacted and Deprecated 
Thanks Apple!)
