ArraySlice指数超出范围斯威夫特 [英] ArraySlice index out of range in Swift

问题描述

我有以下格式的数据。

[\"DATA1-1\",\"DATA1-2\",\"DATA1-3\",\"DATA1-4\",\"\",\"DATA2-1\",\"DATA2-2\",\"DATA2-3\",\"DATA2-4\",\"\",\"DATA3-1\",\"DATA3-2\",\"DATA3-3\",\"DATA3-4\",\"\"].

["DATA1-1","DATA1-2","DATA1-3","DATA1-4","","DATA2-1","DATA2-2","DATA2-3","DATA2-4","","DATA3-1","DATA3-2","DATA3-3","DATA3-4",""].

我需要在阵列的每个组件中执行特定的操作。的组件由，分离。换句话说，我首先需要执行操作[DATA1-1，DATA1-2，DATA1-3，DATA1-4]，然后在[DATA2-1相同的操作， DATA2-2，DATA2-3，DATA2-4]等。

I need to perform specific operations within each component of the array. The components are separated by "". In other words, I first need to perform an operation on ["DATA1-1","DATA1-2","DATA1-3","DATA1-4"], then the same operation on ["DATA2-1","DATA2-2","DATA2-3","DATA2-4"], etc.

首先，我切片阵列分为单独的段，然后在每个迭代段：

First, I slice the array into separate segments, then iterate through each segment:

func arraySliceFunction(airway: [String])
    {           
        // Slice the master array with all combinations of airways into separate arrays
        var airwaySlices = airway.split("")

        // Iterate through the slices of arrays
        for i in 0..<airwaySlices.count
        {
            let sliceComponent = airwaySlices[i]

            // Iterate through each slice
            for var y = 0; y < sliceComponent.count; y++
            {
                print("SLICES COMPONENT: \(sliceComponent[y])")
            }
        }
    }

和崩溃在此行

print("SLICES COMPONENT: \(sliceComponent[y])")

永远是第二次迭代有错误时：致命错误：ArraySlice指数超出范围

always during the second iteration with an error: "fatal error: ArraySlice index out of range".

不知道为什么...

感谢你在前进！

推荐答案

尝试这样的：

func arraySliceFunction(array: [String]) {
    // Slice the master array with all combinations of airways into separate arrays
    // Iterate through the each subArray 
    for subArray in array.split("") {
        // Iterate through each item in subArray
        for item in subArray {
            print("SLICES COMPONENT: \(item)")
        }
    }
}
