iphone - スワイプビューのたびにインデックス0

Question

毎回のインデックスのインデックスは内部で 0 です:

- (UIView *)swipeView:(SwipeView *)swipeView viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view
{
    view = [[MTResultCard alloc] initWithFrame:_swipeView.frame];

    NSDictionary *resultsDictionary = [[MTDataLayer sharedDataLayer].results objectForKey:@"mykey"];

    NSString *key = [[[[MTDataLayer sharedDataLayer].results objectForKey:@"mykey"] allKeysSorted] objectAtIndex:index];
    ((MTResultCard *)view).item = [[[MTDataLayer sharedDataLayer].results objectForKey:@"mykey"] objectForKey:key];

    return view;
}


-(NSArray *)allKeysSorted{

    return [[self allKeys]sortedArrayUsingComparator:^NSComparisonResult(NSString* obj1, NSString* obj2) {
        return [obj1 compare:obj2];
    }];
}

毎回 index = 0 になる理由は何ですか?
