找不到“Init"的重载 - UIImage [英] Could Not Find Overload for 'Init' - UIImage
本文介绍了找不到“Init"的重载 - UIImage的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我升级到最新版本的 Xcode，现在我收到无法找到接受提供的参数的 'Init' 的重载"错误.导致此错误的行是:
I upgraded to the latest version of Xcode and now I'm getting a "Could not find an overload for 'Init' that accepts the supplied argument" error. The line that's causing this error is:
leftDigitImage.animationImages = [UIImage(named: "blink_anim.gif"),UIImage(named: "empty led.png")]
leftDigitImage 是一个定义为:
leftDigitImage is an outlet that's defined as:
@IBOutlet weak var leftDigitImage: UIImageView!
它在以前版本的 Xcode 中运行良好.
It worked fine in the previous version of Xcode.
推荐答案
这样写:
leftDigitImage.animationImages = [UIImage(named: "blink_anim.gif")!, UIImage(named: "empty led.png")!]
问题是 UIImage init(named:) 现在返回一个可选项，所以你需要解开它们.
The problem is that UIImage init(named:) now returns an optional, so you need to unwrap them.
