screenshot of analysis

The static analysis of the 'test' method says that an object is allocated on
line 18 is stored into newMergingList and then never used. However, it is used
in the next line and the retainCount should not be affected.

****


@interface testViewController : UIViewController

- (void)addProductCollection:(id)newProductCollection
removingExisting:(BOOL)removeExisting;
@property (nonatomic, retain) id newProductCollection;

@end

@implementation testViewController

@synthesize newProductCollection = _newProductCollection;

- (void)addProductCollection:(id)newProductCollection
removingExisting:(BOOL)removeExisting
{
}

- (void)test
{
    id newMergingList = self.newProductCollection;
    [self addProductCollection:newMergingList removingExisting:0];
}


@end
