Whenever I want to get data from a plist file I use the following code:
NSString *filePath = [[NSBundle mainBundle] pathForResource:@\"FILE_NAME\" ofType:@\"plis
From an earlier SO answer of mine. Attributes from the info.plist for your project are directly accessible by the following...
[[NSBundle mainBundle] objectForInfoDictionaryKey:key_name];
Your filePath is nil simply because it can't find the file - check spellings & check if the file you are trying to read from is actually in the bundle etc.
