如何从故事板或 xib 加载 iCarousel 视图？

Question

我正在使用一个第 3 方控件 iCarousel 视图来显示具有漂亮动画的视图。

一切正常，我非常了解这个控件。

但直到现在我都在使用手动代码在 iCarousel 视图中添加视图并将其显示在屏幕上但是现在根据我的新要求我有 3 到 4 个新主题需要显示 iCarousel 视图所以下面是我与该视图相关的问题。

如何加载来自 XIB 的不同视图？
如何从 Storyboard 加载视图到 iCarousel 视图？

目前我正在使用以下方法手动添加视图。

viewForItemAtIndex:(NSInteger)index resuingView:(UIView*) view

请帮助我通过 Storyboard/ XIB 实现此目标。

Answer 1

使用 nib 中的自定义视图创建具有倒转轮类型的 iCarousel

   @IBOutlet weak var viewCarousel: iCarousel!

    override func viewDidLoad() {
            super.viewDidLoad()
        viewCarousel.type = .invertedWheel
        viewCarousel.isVertical = true
        viewCarousel.delegate = self
        viewCarousel.dataSource = self
    }

iCarousel 数据源

func numberOfItems(in carousel: iCarousel) -> Int {
    return 25
}

func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
        // use a custom view from nib
        let view = Bundle.main.loadNibNamed("CarouselReuseView", owner: self, options: nil)![0] as! CarouselReuseView
        view.frame.size = CGSize(width: self.view.frame.size.width/2, height: 83.0)
        view.backgroundColor = UIColor.lightGray

        let friend = friendList[index] as friend
        view.lblName.text = friend.fullName
        let url = friend.photo
        let task = URLSession.shared.dataTask(with: URL(string: url)!, completionHandler: {data, response, error in
            if error == nil {
                DispatchQueue.main.async {
                    view.imageView.image = UIImage(data: data!)
                    view.imageView.layer.cornerRadius = view.imageView.frame.size.width/2
                    view.imageView.layer.masksToBounds = true
                }
            }
        })
        task.resume()
        return view
    }

}

Objectiv C

@property (weak, nonatomic) IBOutlet iCarousel *carouselView;


- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    _carouselView.type = iCarouselTypeInvertedWheel;
    _carouselView.vertical = true;
    _carouselView.delegate = self;
    _carouselView.dataSource = self;
    _carouselView.layer.masksToBounds = true;
}

iCarousel 数据源

-(NSInteger)numberOfItemsInCarousel:(iCarousel *)carousel {
    return 10;
}

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

    CustomView* myViewObject = [[[NSBundle mainBundle] loadNibNamed:@"customView" owner:self options:nil] objectAtIndex:0];

    myViewObject.lbl.text = [NSString stringWithFormat:@"%ld",(long)index];

    return myViewObject;
}

这里的 CustomView 是我的 UIView 子类，"customView" 是 UIView Xib 名称希望对你有帮助

试试这个：

-(UIView *) carousel:(iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view{
        UIView  *globleView = (UIView *)view;
        if (!globleView) {
            globleView = [[[NSBundle mainBundle] loadNibNamed:@"yourView" owner:self options:nil] objectAtIndex:0];;
            globleView.backgroundColor = [UIColor clearColor];
            UIImageView *imageView = [[UIImageView alloc]initWithFrame:globleView.frame];

            imageView.tag = 100;
            [globleView addSubview:imageView];

            UILabel *lblFeatureRecipeName = [[UILabel alloc]initWithFrame:CGRectMake(15, ViewHeight(globleView) -50, ViewWidth(globleView)-40, 50)];

            lblFeatureRecipeName.tag = 101;
            [globleView addSubview:lblFeatureRecipeName];
            if (index == 0) {
                [self refreshCarousleViewWithView:globleView withIndex:index];
            }
        }
        return globleView;
    }
