-[NSDictionary dictionaryWithContentsOfFile] returning nil on iPad; returning dictionary in the simulator

I have a method:

#define ROOT_ASSETS_PATH @"/assets/"

...

-(NSMutableDictionary*) getContentsOfPlist{
    NSString *pageContentPlistPath = [[[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent: ROOT_ASSETS_PATH] stringByAppendingPathComponent:@"content.plist"];

    NSMutableDictionary *mDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:pageContentPlistPath];
    return mDicitonary;
}

On the simulator. this returns a dictionary. On the iPad, it returns nil. Made sure the extension case matches that in the call as well.

Any ideas?

The issue was case after all. Case of the filename didn't match the case I put in the parameter. OSX doesn't care, but the iPad does.

+ (id)dictionaryWithContentsOfFile:(NSString *)path

Parameters

path

A full or relative pathname. The file identified by path must contain a string representation of a property list whose root object is a dictionary.

Return Value

A new dictionary that contains the dictionary at path, or nil if there is a file error or if the contents of the file are an invalid representation of a dictionary.

So, you have to set a full path to your file (or an appropriate relative path)

Note also that the app bundle is read-write on Simulator but read-only on device.

Also it is good idea to use:

[NSPropertyListSerialization propertyListWithData:options:format:error:]

Instead of direct NSDictionary initialization. If something will fail, it should return a nice error for you.

Try removing the slashes in your #define. stringByAppendingPathComponent will add the slashes for you. Not sure why this would work in the Simulator.
