Question

我在向iCarousel＆＃34; viewForItemAtIndex＆＃34;添加视图时遇到了问题。方法

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{


UIView *sub = nil;
//iCarousel *temp;

//create new view if no view is available for recycling
if (view == nil)
{
    UIViewController * viewController = [self.storyboard  instantiateViewControllerWithIdentifier:@"UIidentifier"];
    view = [viewController.view viewWithTag:20];

    CGRect  Frame = CGRectMake(view.frame.origin.x, view.frame.origin.y + 100, view.frame.size.width, view.frame.size.height);
    view.frame = Frame;
}

UILabel *label=(UILabel*)[view viewWithTag:23];
label.text = [[listOfAnimalsNames objectAtIndex:index]nameOfTheCompanie];
return view;

}

我想展示一个UIView＆＃34; mockUp＆＃34;并使用＆＃34;索引＆＃34;填充标签中的一些数据。在iCarousel中，我创建了自己的UIViewController，其中包含＆＃34; mockup＆＃34; UIView的。问题是，当我调用这个UIView时（如在代码中）没有任何反应。（我在加载数据后使用reloadData方法）

为什么每个视图都需要自己的ViewController？它们都应该由控制iCarousel视图（或至少它的数据源）控制。此外，UILabel只应实例化一次。

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

if (view == nil)
{
    view = [UIView alloc] initWithFrame:CGRectMake(...);
    UILabel *label=[[UILabel alloc] initWithFrame:(...)];
    [view addSubview:label];
}

label.text = [[listOfAnimalsNames objectAtIndex:index]nameOfTheCompanie];
return view;
}

将自定义UIView添加到iCarousel
