You have several approaches:

1. you could split your methods into 2 different categories:

   //-- MyClass1.m
   @implementation MyClass (part1)
   
   @end
   
   //-- MyClass2.m
   @implementation MyClass (part2)
   
   @end
   

   I defined 2 categories for symmetry reason; of course you also need a "base" @implementation of your class (i.e., without the category specifier); you can choose whether you define a "base" and and extension category, or "base" and two categories, etc...

2. or you might try including the second .m file inside of the first one:

       //-- MyClass1.m
       @implementation MyClass
   
       
   
       #include "MyClass2.m"
   
       @end
   

Both should work.

Let alone the possibility of refactoring your class, which would be the best option.
