I think you are trying to insert a C type in the dictionary. NSDictionaries can only contain objects ( https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSDictionary_Class/Reference/Reference.html ):

• (void)setValue:(id)value forKey:(NSString *)key <-- the value must be an object

To insert the long value as an object, you can make a NSNumber *n = [NSNumber numberWithLong:longValue]; When you need to read it back, you can have [n longValue].
