NOT(!) in objective c

for (int i=0 ; i<=[secondSplitArrayValue count]; i++)   
{    
  if (![[secondSplitArrayValue objectAtIndex:i] isEqualToString:@"NULL"] ||  
  ![[splitArrayValue objectAtIndex:i] isEqualToString:@"Error"]   
    {  
        [secondSplitArrayValue removeObjectAtIndex:i];  
    }  
}

I am trying to remove value of array at particular index where string is NOT EQUAL (!=) to NULL or Error. But in debugging time object is removed where NULL and Error present but I want to remove object where Null and Error not present.

Try this.

for (int i=0 ; i<=[secondSplitArrayValue count]; i++)   
{    
  if (([[secondSplitArrayValue objectAtIndex:i] isEqualToString:@"NULL"] == FALSE) ||  
  ([[splitArrayValue objectAtIndex:i] isEqualToString:@"Error"] == FALSE))

    {  
        [secondSplitArrayValue removeObjectAtIndex:i];  
    }  
}

}

See if this helps

You're probably looking for this I think: 

for (int i=0 ; i<=[secondSplitArrayValue count]; i++)   
{    
  if (!([[secondSplitArrayValue objectAtIndex:i] isEqualToString:@"NULL"] ||  
  [[splitArrayValue objectAtIndex:i] isEqualToString:@"Error"])   
    {  
        [secondSplitArrayValue removeObjectAtIndex:i];  
    }  
}

This way you inverse the boolean operation only after you have completed the check for both cases, and the OR operation of both of the resulting checks.
