Getting data from the Info plist
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.
I do not think there is another way (unless it is the info.plist file then see Damo's comment), instead I would focus on figuring out why the filePath is nil, perhaps the plist file is no longer under target>build phases>copy bundle resources?
Replace
[[NSBundle mainBundle] pathForResource:@"FILE_NAME" ofType:@"plist"]with
[[NSBundle mainBundle] pathForResource: @"Info" ofType: @"plist"]
