Question

i have an NSDictionary that contain in value and i need to get this value
i have tried to get the value using the following code:

[NSTimer scheduledTimerWithTimeInterval:0.01  
                         target:self
                               selector:@selector(timerMovelabel:) 
                               userInfo:
            [NSDictionary dictionaryWithObject:var forKey:@"var1"]
     , [NSMutableDictionary dictionaryWithObject:[NSNumber numberWithInt:23] forKey:@"var2"]

i have tried to get the value using the following methods

1. int intvar = [[[timer userInfo] objectForKey:@"var2"] intValue];

2. NSNumber *numbervar = [[timer userInfo] objectForKey:@"var2"];
NSInteger intvar = [num intValue];

3. Follows:

   [self method:[[[timer userInfo] objectForKey:@"var2"] intValue]];
   
   
   - (void)timerMovelabel:(NSTimer *)timer {
       //here i execute one of the steps 1,2 and 3 but i didn't get any result all values are null
   }
   
   
   - (void) method:(NSInteger)dir 
   { 
        NSLog(@"%d",dir);
   }

The setup of the timer appears to be wrong. You can not pass more than one dictionary to the userInfo parameter.

Try:

[NSTimer scheduledTimerWithTimeInterval:0.01
                                 target:self
                               selector:@selector(timerMovelabel:)
                               userInfo:
         [NSDictionary dictionaryWithObjectsAndKeys: var, @"var1", 
                                                     [NSNumber numberWithInt:23], @"var2",
                                                     nil]
                               repeats:NO];

EDIT: Added repeats parameter, thanks Bavarious.
