    - (void)startMyTimer {
        /* ... Some stuff ... */
        NSDictionary *userDict;
        userDict = [NSDictionary dictionaryWithObjectsAndKeys:someValue,
                                                              @"value1",
                                                              someOtherValue,
                                                              @"value2", nil];

        [NSTimer scheduledTimerWithTimeInterval:0.1
                                         target:self
                                       selector:@selector(callMyMethod:)
                                       userInfo:userDict
                                        repeats:YES];
}
    - (void)callMyMethod:(NSTimer *)theTimer {
        NSString *value1 = [[theTimer userInfo] objectForKey:@"value1"];
        NSString *value2 = [[theTimer userInfo] objectForKey:@"value2"];
        [self myMethod:value1 setValue2:value2];
    }
