Ios 如何在Swift的tableview单元格中添加自定义imageview？

我需要做的是将圆形图像添加到uitableview上的单元格中。如何才能做到这一点

我尝试了一些代码，但根本不起作用，以下是我的代码：

let imageName = "person.png"
    let image = UIImage(named: imageName)
    var imageView = UIImageView(image: image!)

    imageView = UIImageView(frame: CGRectMake(0, 0, 100, 100))
    imageView.layer.borderWidth=1.0
    imageView.layer.masksToBounds = false
    imageView.layer.borderColor = UIColor.whiteColor().CGColor
    imageView.layer.cornerRadius = 13;
    imageView.clipsToBounds = true

    cell.imageView!.image = imageView

我得到了这个错误：

无法将“UIImageView”类型的值分配给“UIImage”类型的值

制作一类要加载到

表视图中的
单元格

类
cellcoment
：

class CellComment: UITableViewCell 
{
  @IBOutlet weak var imageV_profile: UIImageView!

    override func awakeFromNib() {

          super.awakeFromNib()

          imageV_profile.layer.cornerRadius = 25

         imageV_profile.layer.masksToBounds = true
    }
}

现在在tableview中加载此单元格，如下所示

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{

       var  cell:CellPost! = tableView.dequeueReusableCellWithIdentifier("CellPost") as? CellPost

       if (cell == nil)
       {
          let nib:Array = NSBundle.mainBundle().loadNibNamed("CellPost", owner: self, options: nil)
          cell = nib[0] as? CellPost
       }

      cell.imageV_profile.image = UIImage(named: "Your image name")

      return cell
}

不能以这种方式指定图像。但是你可以这样做

首先添加可调整图像大小的功能：

func resizeImage(image:UIImage, toTheSize size:CGSize)->UIImage{


    var scale = CGFloat(max(size.width/image.size.width,
        size.height/image.size.height))
    var width:CGFloat  = image.size.width * scale
    var height:CGFloat = image.size.height * scale;

    var rr:CGRect = CGRectMake( 0, 0, width, height);

    UIGraphicsBeginImageContextWithOptions(size, false, 0);
    image.drawInRect(rr)
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext();
    return newImage
}

之后，您可以指定图像：

let imageName = "11749-simple.jpg"
let image = UIImage(named: imageName)
let newImage = resizeImage(image!, toTheSize: CGSizeMake(70, 70))
var cellImageLayer: CALayer?  = cell.cellImage.layer
cellImageLayer!.cornerRadius = cellImageLayer!.frame.size.width / 2
cellImageLayer!.masksToBounds = true
cell.cellImage.image = newImage

let imageName = "11749-simple.jpg"
let image = UIImage(named: imageName)
cell.cellImage.image = image?.circleMask

结果将是：


或者您可以尝试此扩展：

extension UIImage {
var circleMask: UIImage {
    let square = size.width < size.height ? CGSize(width: size.width, height: size.width) : CGSize(width: size.height, height: size.height)
    let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: square))
    imageView.contentMode = UIViewContentMode.ScaleAspectFill
    imageView.image = self
    imageView.layer.cornerRadius = square.width/2
    imageView.layer.borderColor = UIColor.whiteColor().CGColor
    imageView.layer.borderWidth = 5
    imageView.layer.masksToBounds = true
    UIGraphicsBeginImageContext(imageView.bounds.size)
    imageView.layer.renderInContext(UIGraphicsGetCurrentContext())
    let result = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return result
    }
}

要回答的扩展学分。
请尝试此代码。这正是你想要的

let imageName = "person.png"
let image1 = UIImage(named: imageName)

var imageView = UIImageView(frame: CGRectMake(5, 5, 100, 100))
imageView.layer.borderWidth=1.0
imageView.layer.masksToBounds = true
imageView.layer.borderColor = UIColor.whiteColor().CGColor
imageView.layer.cornerRadius = 50;// Corner radius should be half of the height and width.
imageView.image = image1
cell.addSubview(imageView)

Swift 5的延期

extension UIImage {
var circleMask: UIImage {
    let square = size.width < size.height ? CGSize(width: size.width, height: size.width) : CGSize(width: size.height, height: size.height)
    let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: square))
    imageView.contentMode = UIView.ContentMode.scaleAspectFill
    imageView.image = self
    imageView.layer.cornerRadius = square.width/2
    imageView.layer.borderColor = UIColor.white.cgColor
    imageView.layer.borderWidth = 5
    imageView.layer.masksToBounds = true
    UIGraphicsBeginImageContext(imageView.bounds.size)
    imageView.layer.render(in: UIGraphicsGetCurrentContext()!)
    let result = UIGraphicsGetImageFromCurrentImageContext()!
    UIGraphicsEndImageContext()
    return result
    }
}

扩展UIImage{
var circleMask:UIImage{
让正方形=size.width

只需替换最后一行即可。cell.imageView=imageView，然后选中它说“无法在单元格中分配‘imageView’”确定替换最后一行，如cell.imageView.image=image abd，然后选中cell。imageView。image=image | |只需将imageView替换为imageView如果是这样，只需使用“let image”。图像保持原样只是看看嘿Ega Setya Putra。。。这是您的代码的一个非常简单的修改代码。这是一个简单的方法。它确实给了我一个圆形的图像，但是图像比tableview单元格大。感谢BTW，然后更改imageview的大小，如“var imageview=UIImageView（帧：CGRectMake（5,5,60,60）），以及imageview.layer.cornerRadius=30；请注意，此处的扩展并没有保留UIImage比例，它可能与此相关。如果愿意，可以使用原始比例从结果创建新的UIImage。

extension UIImage {
var circleMask: UIImage {
    let square = size.width < size.height ? CGSize(width: size.width, height: size.width) : CGSize(width: size.height, height: size.height)
    let imageView = UIImageView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: square))
    imageView.contentMode = UIView.ContentMode.scaleAspectFill
    imageView.image = self
    imageView.layer.cornerRadius = square.width/2
    imageView.layer.borderColor = UIColor.white.cgColor
    imageView.layer.borderWidth = 5
    imageView.layer.masksToBounds = true
    UIGraphicsBeginImageContext(imageView.bounds.size)
    imageView.layer.render(in: UIGraphicsGetCurrentContext()!)
    let result = UIGraphicsGetImageFromCurrentImageContext()!
    UIGraphicsEndImageContext()
    return result
    }
}
