Calling selectors from multiple file

Question

In AppDelegate.m, I've defined

#import "AppDelegate.h"
#import "allerta.h"

@implementation AppDelegate
@synthesize window = _window;

-(void)awakeFromNib {

// Add an observer that will respond to loginComplete
[[NSNotificationCenter defaultCenter] addObserver:self 
                                         selector:@selector(alerticonstatus:) 
                                             name:@"alert" object:nil];

// Post a notification to loginComplete
[[NSNotificationCenter defaultCenter] postNotificationName:@"alert" object:nil];
}
@end

I want to call alerticonstatus from allerta.h:

#import <Foundation/Foundation.h>
@interface allerta : NSObject{
}

-(void)alerticonstatus:(NSNotification *)note;

@end

allerta.m:

#import "allerta.h"
@implementation allerta

-(void)alerticonstatus:(NSNotification *)note {

NSLog(@"called alerticonstatus");

}
@end

Can I import a function whit @selector from another file like allerta.h? Now I have SIGABRT error. Can you help me? Thanks.

Change you method for this, it work:

#import "AppDelegate.h"
#import "allerta.h"

@implementation AppDelegate
@synthesize window = _window;

-(void)awakeFromNib {
   allerta *_allerta = [allerta alloc]; //allocation memory

   // Add an observer that will respond to loginComplete
   [[NSNotificationCenter defaultCenter] addObserver:_allerta //here you called self, but you need to call your class allerta
                                         selector:@selector(alerticonstatus:) 
                                             name:@"alert" object:nil];
    [_allerta release]; //kill _allerta class if you don't need more

    // Post a notification to loginComplete
    [[NSNotificationCenter defaultCenter] postNotificationName:@"alert" object:nil];
}
@end

When you create class files, set firs letter big, like as "Allerta".
