我是swift的新手
tableview包含多个图像正常运行代码:
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Media", for: indexPath)as! MediaCustomTableViewCell
let row = indexPath.row
let media = Mediainfo[row] as MediaEvent
cell.DisplayDate.text = media.date
cell.DisplayName.text = media.eventName
cell.selectionStyle = .none
cell.DisplayImage.downloadImageFrom(link:media.bannerImages, contentMode: UIViewContentMode.scaleAspectFit)
return cell
}
override func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return CGFloat.leastNormalMagnitude
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)
{
let media = Mediainfo[(indexPath.row)] as MediaEvent
let ImageStoryboard = UIStoryboard(name: "Main", bundle: nil)
let ImageController = ImageStoryboard.instantiateViewController(withIdentifier: "IMAGESCOL")as!ImagesCollectionViewController
这里我将图片传递到集合视图但它不起作用:
ImageController.RecivedData1 = media.bannerImages
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let tabcontroller = storyboard.instantiateViewController(withIdentifier: "IMAGEVID") as! UITabBarController
navigationController?.pushViewController(tabcontroller, animated: true)
}
在tableview中选择任何图像后,单元格图像应显示在带有集合视图的选项卡栏中。我正在显示图像和视频类别,我可以使用标签栏控制器
数据传递给:
Tableview --->标签栏控制器===> 2个集合视图
如何使用标签栏控制器将tableview图像数据传递给集合?
答案 0 :(得分:1)
在您的代码中
let ImageStoryboard = UIStoryboard(name: "Main", bundle: nil)
let ImageController = ImageStoryboard.instantiateViewController(withIdentifier: "IMAGESCOL") as! ImagesCollectionViewController
ImageController.RecivedData1 = media.bannerImages
这些代码不会执行任何操作,因为您声明了ImageController
,但您不使用/显示它。
因此,根据上下文,我假设UITabBarController
中有Main.storyboard
,而UITabBarController
有两个UIViewController
,其中一个是ImageController
}。如果我是对的,你可以尝试以下代码:
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let tabBarController = storyboard.instantiateViewController(withIdentifier: "IMAGEVID") as! UITabBarController
// You should access the `imageController` through your `tabBarController`,
// not instantiate it from storyboard.
if let viewControllers = tabBarController.viewControllers,
let imageController = viewControllers.first as? ImageController {
imageController.recivedData1 = media.bannerImages
}
navigationController?.pushViewController(tabBarController, animated: true)
另一个建议是你应该使用驼峰案例来命名你的属性。有关详细信息,请参阅this style guideline。
