Swift Tableview单元格未在部分上显示背景图像

Question

Inside cellForRowAtIndexPath method I am atribtuting to the cell a background image like so:

let image = UIImage(named: "other_car")
let imageView = UIImageView(image: image)
cell.backgroundView = imageView

but the cell seems the same. How to correct this?

Answer 1

You're creating an instance of UIImageView without setting its frame.

Set imageView.frame = CGRect(x: 0, y: 0, width: 100, height: 200) for example to set its frame and make it visible.

Also you can set the frame directly while creating it like this:

let imageView = UIImageView(frame:CGRectMake(0, 0, 100, 200))

Then you can set the image with:

imageView.image = UIImage(named: "other_car")

or

imageView.image = image // your UIImage instance

Answer 2

What I missed is this: before change the cell.backgroundView = imageView I inserted this peace of code, which cleared the color inside the cell:

cell.backgroundColor = UIColor.clearColor()

Hope it helps other people
