我正在使用一个 3rd 方控件 iCarousel
View 来显示带有漂亮动画的 View 。
一切正常,我非常了解这种控制。
但到目前为止,我使用手动代码在 iCarousel
View 中添加 View 并将其显示在屏幕上,但现在根据我的新要求,我有 3 到 4 个新主题需要显示 iCarousel
View ,因此下面是我与该 View 相关的问题.
XIB
加载不同的 View ? Storyboard
加载到 iCarousel
View ? 目前我正在使用以下方法手动添加 View 。
viewForItemAtIndex:(NSInteger)index resuingView:(UIView*) view
请帮助我通过
Storyboard/ XIB
实现这一目标。 最佳答案
使用 nib 的自定义 View 创建带有倒轮类型的 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
}
}
目标 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 CustomView 是我的 UIView 子类,“customView”是 UIView Xib 名称
我希望这对你有帮助
