iCarousel加载UIView的问题

在应用中用到iCarousel来显示视图列表,但是遇到两个问题:

1.如果设置可见列表的数目为3,索引视图就会显示为3的倍数。

2.如果不设置,那么第一个和最后一个索引视图就会显示。

现在这个重用视图已经把我搞迷糊了。

代码:

-(void)viewWillAppear:(BOOL)animated
{



ViewArray=[[NSMutableArray alloc]init];
for (int i=0; i<26; i++) {
 [ViewArray addObject:views];
    [carousel1 reloadData];

}
NSLog(@"%@",ViewArray);
}


- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
//return the total number of items in the carousel
return 26;
}


- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
 UIView *sub=nil;
 if (view==nil) {


view=[[UIView alloc]initWithFrame:CGRectMake(0, 0, 900, 387)];

    capitalBG.frame=CGRectMake(28, 29, 221, 329);
    capitalBG.tag=11;
    [view addSubview:capitalBG];

    capitalImage.frame=CGRectMake(28, 29, 221, 329);
           [view addSubview:capitalImage];
    capitalImage.tag=12;
    smallBG.frame=CGRectMake(678, 111, 198, 166);
           [view addSubview:smallBG];
    smallBG.tag=21;
    smallImage.frame=CGRectMake(678, 111, 198, 166);
           [view addSubview:smallImage];
    smallImage.tag=22;

}

else
{

}

capitalBG.frame=CGRectMake(28, 29, 221, 329);
[capitalBG setImage:[UIImage imageNamed:@""]];
[view addSubview:capitalBG];

capitalImage.frame=CGRectMake(28, 29, 221, 329);
[capitalImage setImage:[[[Global ImageCollection]objectForKey:@"CapitalWrite"]objectAtIndex:index]];
[view addSubview:capitalImage];

smallBG.frame=CGRectMake(678, 111, 198, 166);
[smallBG setImage:[UIImage imageNamed:@""]];
[view addSubview:smallBG];

smallImage.frame=CGRectMake(678, 111, 198, 166);
[smallImage setImage:[[[Global ImageCollection]objectForKey:@"SmallWrite"]objectAtIndex:index]];
[view addSubview:smallImage];
 return view;
}


- (CGFloat)carousel:(iCarousel *)carousel valueForOption:(iCarouselOption)option withDefault:(CGFloat)value
{
if (option == iCarouselOptionSpacing)
{
    return value * 1.1f;
}

if (option==iCarouselOptionVisibleItems) {
    return 3;
}
return value;
}
