iOS Calling a method across implementation files

[mcannell]

I am new to Objective-C, Cocoa, & iPhone SDK.

This seems to me like it should be very easy to do but I have spent hours trying to find the solution.

I have a RootViewController with a method in it that I want to call from MainView.m. Why isn't this a very simple thing to do? I've searched, read through Objective-C books, begged, nothing works...



RootViewController.m
---------------------------------

-(void) myMethod {
// do something amazingly great
}


MainView.m
----------------------------------
#import "MainView.h"
#import "RootViewController.h"

-(IBAction) myOutlet{
// do some calculations here
// set some variables here

//Now call method inside RootViewController
[RootViewController toggleView];

}

BTW, It builds but when the button is clicked I get:


__TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION__

0x95490fb0 <+0000> push %ebp
0x95490fb1 <+0001> mov %esp,%ebp

Well, I won't give you the outright answer but I will give you somewhat of a hint. You have myMethod declared as an instance method but you are trying to access it using the class method approach.
