NSInteger positionToLoad;

```
            GMGridViewCell *cell = [self newItemSubViewForPosition:positionToLoad];
            [self addSubview:cell];

===========Whether should change to this?==============
NSInteger positionToLoad = 0;

```
            GMGridViewCell *cell = [self newItemSubViewForPosition:positionToLoad < 0 ? 0 : positionToLoad];
            [self addSubview:cell];
```
