ios – 如何在Swift中将AnyObject类型转换为Int

if let result = lasrIDArray.flatMap( {$0["(self.selectedTitle)"]} ).first {      
    print(result)

    if let number = result as? NSNumber {
        let tag = number.integerValue
        let currentScroll = view.viewWithTag(Int(api.selectedCatID)!) as! UIScrollView
        let lastImgVw = currentScroll.viewWithTag(tag) as! UIImageView
        print(lastImgVw.frame.origin.y)
    }
}

我不知道您的代码,但这对您有所帮助.

您可以通过这种方式获取AnyObject值…

let data :AnyObject = "100"
let score = Int(data as! String)! //Force Unwrap optional value it will be dengerious for nil condition.
print(score)

或者也尝试这种方式

let hitCount = "100"
let data :AnyObject = hitCount as AnyObject //sometime Xcode will ask value type
let score = Int(data as? String ?? "") ?? 0
print(score)

输出 –

Swift 3.1&斯威夫特4

let hitCount = "100"
let data :Any = hitCount //Any type Value passing here 
let score = Int(data as? String ?? "") ?? 0
print(score)

输出 –
