Pseudo Code...

@interface FoobarException : NSException
@end

@implementation FoobarException
@end

@interface Foo : NSObject
- (void) doSomething;
- (void) doSomethingElse;
@end

@implementation Foo

- (void) doSomething
{
  // do something

  if( "something went wrong" )
  {
    NSException *e;

    e = [FoobarException exceptionWithName: @"FoobarException"
            reason: @"Something went wrong" userInfo: nil];
    @throw e;
  }

  return;
}

- (void) doSomethingElse
{
  // do something else

  return;
}

@end

void main(void)
{
  Foo *bar;
  
  bar = [[Foo alloc] init];

  @try
  {
     [bar doSomething];
  }
  @catch(FoobarException *e)
  {
    printf( "%s: ", [[e name] cString] );
    exit(EXIT_FAILURE);
  }
  // you can add more @catch statements here
  @finally
  {
    [bar doSomethingElse];
  }

  exit(EXIT_SUCCESS);
}
