iCarousel未显示,方法未被处理

Question

我试图通过两侧淡入淡出实现左侧iCarousel对象的权利.

所以我将GtiHub项目导入我的应用程序,为i​​Carousel分配了一个UIView ...将它链接到我的MainViewController上的IBOutLet并传递了Delegate以及DataSource,就像UITableViewController一样.

虽然它不会出现,我不确定可能导致这个问题的原因.

我的iCarousel DataSource是一个NSMutableArray*项目; 设计如下:

for (int i = 0; i < 100; i++)
{
    [_items addObject:@(i)];
}

我正在ViewDidLoad中初始化iCarousel,如下所示

- (void)viewDidLoad
{
  [super viewDidLoad];
  //Initialize Carousel
  _carousel = [[iCarousel alloc] init];
  _carousel.delegate = self;
  _carousel.dataSource = self;

  //Carousel Testing Data
  for (int i = 0; i < 100; i++)
  {
     [_items addObject:@(i)];
  }

  //configure carousel
  _carousel.type = iCarouselTypeRotary;

}

我的旋转木马代表方法如下:

#pragma mark -
#pragma mark iCarousel methods

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

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

   //create new view if no view is available for recycling
   if (view == nil)
   {
      view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)];
      ((UIImageView *)view).image = [UIImage imageNamed:@"page.png"];
      view.contentMode = UIViewContentModeCenter;

      label = [[UILabel alloc] initWithFrame:view.bounds];
      label.backgroundColor = [UIColor clearColor];
      label.font = [label.font fontWithSize:50];
      label.tag = 1;
      [view addSubview:label];
   }
  else
   {
      //get a reference to the label in the recycled view
      label = (UILabel *)[view viewWithTag:1];
   }


  label.text = [_items[index] stringValue];
  return view;
}

 - (CGFloat)carousel:(iCarousel *)carousel valueForOption:(iCarouselOption)option withDefault:(CGFloat)value
 {
    switch (option)
    {
       case iCarouselOptionFadeMin:
           return -0.2;
       case iCarouselOptionFadeMax:
           return 0.2;
       case iCarouselOptionFadeRange:
           return 2.0;
       default:
           return value;
     }
  }

故事板中的所有内容似乎都是连接起来的,数据应该呈现出来,出了什么问题以及如何解决这个问题？

Answer 1

由于在加载视图后设置了DataSource数组(_items):

1. 确保故事板中的轮播视图确实具有控制器的IBOutlet,但不是链接到文件所有者(控制器或视图)的"委托"和"数据源".

2. 设置_carousel.delegate和_carousel.dataSource以"自我"只有经过初始化和更新数据源阵列(在这种情况下_items).
