arrays - 无法使用类型为 '[ClassName.StructName]' 的索引下标类型为 'ClassName.StructName' 的值

Question

我遇到了这个问题，但还没有找到任何解决方案。

结构

struct hourSlot{
        lazy var timeWorkingString = "\(startTimeStructString) -  \(endTimeStructString)"
        var startTimeStructString = "null"
        var endTimeStructString:String = "null"
        (Some logic here)
}

这里的问题:

Cannot subscript a value of type '[WorkTimeModifer.hourSlot]' with an index of type 'WorkTimeModifer.hourSlot'

var hoursArray = [hourSlot]()
func updateTable(){
        for index in hoursArray{
            let timeFinal:String = hoursArray[index].timeWorkingString
        }
}

提前致谢

Answer 1

你需要使用 Int 类型当你下标一个数组而不是索引在这里它是类型 hourSlot

for item in hoursArray {
    let timeFinal = item.timeWorkingString
}

或

for (index,item) in hoursArray.enumerated() {
    let timeFinal = hoursArray[index].timeWorkingString
}
