在swift中从发件人那里获取UIImage

Question

我有一个UIImageView表格单元格,我添加了一个tapGesture.我想访问UIImageViewhandleTap方法.

这是TableCell中Image的代码:

func setImageForCell(cell:ImageCell, indexPath:NSIndexPath) {
    var image : UIImage = UIImage(named: "brunnen1")!

    cell.customImageView.userInteractionEnabled = true
    cell.imageView!.tag = indexPath.row;
    var tapGestureRecognizer = UITapGestureRecognizer(target:self, action:Selector("handleTap:"))
    tapGestureRecognizer.numberOfTapsRequired = 1;
    cell.customImageView.addGestureRecognizer(tapGestureRecognizer)
    cell.customImageView.image = image
}


func handleTap(sender : UIView) {
    // get the UIImageview from the sender, i guess ?

}

我想我必须把它从UIView？

Answer 1

试试这个代码.

func handleTap(sender : UITapGestureRecognizer) {
    let imgView = sender.view as! UIImageView
    // Do something.
}

由于你使用手势识别器,所以handleTap发送者将是UITapGestureRecognizer.手势识别器具有您想要的功能.

var view: UIView? { get }//手势附加到的视图.通过使用addGestureRecognizer:方法将识别器添加到UIView来设置
