问题描述

我正在尝试以编程方式创建 UIImage 视图,我有一个新视图并尝试这样做

I'm trying to create a UIImage View programmatically, I have a new view and I tried doing this

let imageName = "yourImage.png"
yourview.backgroundColor = UIColor.colorWithPatternImage(UIImage(named:imageName))

这不起作用,因为我不知道第二行中的 yourview 应该是什么.

this did not work because I don't know what this should be yourview in the second line.

Question: How do I make a UIImageView appear on the screen by coding it instead of doing it in the storyboard

推荐答案

首先你从你的图像文件创建一个 UIImage,然后从它创建一个 UIImageView:

First you create a UIImage from your image file, then create a UIImageView from that:

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

最后,您需要给 imageView 一个框架并将其添加到您的视图中以使其可见:

Finally you'll need to give imageView a frame and add it your view for it to be visible:

imageView.frame = CGRect(x: 0, y: 0, width: 100, height: 200)
view.addSubview(imageView)
