Here is my interface : 

```
@interface AddRatingViewController ()
    @property (nonatomic, copy) NSMutableArray *categoryFromDb;
@end

```

The following code is in `viewDidLoad` method: 

```
NSManagedObjectContext *managedObjectContext = [self managedObjectContext];

NSFetchRequest *fetchRequest2 = [[NSFetchRequest alloc] initWithEntityName:@"Categories"];
[fetchRequest2 setPredicate:pre];

self.categoryFromDb = [[managedObjectContext executeFetchRequest:fetchRequest2 error:nil] mutableCopy];

if ([self.categoryFromDb count] > 0) {
    NSString *strUrl1 = [self.categoryFromDb valueForKey:@"rank1Img"];

}

```

`NSLog` shows that, the value of strUrl1 is : 

```
(
"assets-library://asset/asset.JPG?id=98E14854-7DA2-4B1F-9B0B-EEDCF3390DF3&ext=JPG"
)

```

But it should be only: 

> 
> assets-library://asset/asset.JPG?id=98E14854-7DA2-4B1F-9B0B-EEDCF3390DF3&ext=JPG
> 
> 
> 

It seems that, the `strUrl1` is getting `NSArray` instead of string value. Now my question is that, how can I remove this `("` from the string
Or, 
How can I get string instead of array? 
Or any other suggestion.
