I encounter memory leak with `stringWithCString`, can anybody find the memory leak in `stringWithCstring` function?

```
SomeView *detailViewController = [[SomeView alloc] initWithNibName:@"SomeView" bundle:nil];
detailViewController.test = [NSString stringWithCString:"abc" encoding:UTF8_ENCODING];

```

the property in SomeView for test variable is

```
@property (nonatomic,copy) NSString* test;

```

Is my property declared correctly?
