How to print a NSInteger value from an NSManagedObject using NSLog

Question

When I try to print an integer value to the console that is retrieved from an NSManagedObject, it displays a 6 or 8 digit value (the object ID?). However, if I use the debugger 'Print Description to Console' is shows up as the single digit value I expect. For example, I assign the object 'sequence' to an NSInteger and then display using an NSLog format string: ``` MyProcess *myProcess = [array objectAtIndex:i]; NSInteger sequence = [[NSNumber numberWithInteger:(NSInteger)myProcess.sequence] intValue]; NSLog(@"sequence = %d",myProcess.sequence); ``` Console output is: ``` 2009-10-06 16:11:05.871 MyProcess[33185:20b] sequence = 565256 ``` But when I try 'Print to Console' from the debugger, I see the value 1: ``` (entity: MyObject; id: 0x3f2d540 ; data: { sequence = 1; ; }) ``` Your help is appreciated!

Accepted Answer

What you get from your NSManagedObject would be a NSNumber, I think. It's easy to print that:

```
MyProcess *myProcess = [array objectAtIndex:i];
NSLog(@"sequence = %@", myProcess.sequence);
```

or, if you really need the NSInteger:

```
MyProcess *myProcess = [array objectAtIndex:i];
NSLog(@"sequence = %i", [myProcess.sequence integerValue]);
```

I think that in this bit of code

```
NSInteger sequence = [[NSNumber numberWithInteger:(NSInteger)myProcess.sequence] intValue];
```

the (NSInteger)myProcess.sequence actually gets the memory address of the NSNumber. You can't just cast an NSNumber into an NSInteger.
