iphone - Swift 从数组中删除给定值

Question

我有一个简单的数组

var specs : [String] = [Button1,Button2,Button3,Button4]

如何在我的错误数组中找到某个值(类型 Button3)并因此取消？

Answer 1

您可以使用find() 全局函数来检索索引:

var specs : [String] = ["Button1","Button2","Button3","Button4"]

let index = find(specs, "Button3")

然后，一旦验证该元素存在(find 返回一个可选的)，将其删除:

if let index = index {
    specs.removeAtIndex(index)
}
