ios - 找不到接受提供的参数的重载 'init'

Question

        var segmentedControlImages: [AnyObject] = [UIImage(named: "likeIcon"), UIImage(named: "dislikeIcon")];

为什么这段代码会产生这个错误？真的很困惑

请帮忙

Answer 1

因为，UIImage(named:)返回 Optional .和 Optional<UIImage>不可转换为 AnyObject .

你可以强制打开它们:

var segmentedControlImages: [AnyObject] = [
    UIImage(named: "likeIcon")!,
    UIImage(named: "dislikeIcon")!
]
