Question

我有一系列字典，将用于collectionView中的单元格。我是新手，所以我尝试找到最佳的存储方式。

现在我使用此代码：

var collectionViewData: [collectionViewStruct] = {
    var cell_1 = collectionViewStruct()
    cell_1.title = "..."
    cell_1.text = "..."
    cell_1.firstColor = "C68CF2"
    cell_1.secondColor = "EFA8CA"

    var cell_2 = collectionViewStruct()
    cell_2.title = "..."
    cell_2.text = "..."
    cell_2.firstColor = "C68CF2"
    cell_2.secondColor = "EFA8CA"

    return [cell_1, cell_2]
}()

有没有一种方法不写每个var作为回报？

如何一次返回所有变量？

或者也许有更好的方法来存储这些数据？

先谢谢了：）

要实现此目的，您可以使用私有属性，然后将其返回，例如：

    private var _suggestions: [suggestionsStruct] = [suggestionsStruct]()
    var suggestions: [suggestionsStruct] {
    get{

        if _suggestions.count > 0{
            var suggestion_1 = suggestionsStruct()
            suggestion_1.title = "..."
            suggestion_1.text = "..."
            suggestion_1.firstColor = "C68CF2"
            suggestion_1.secondColor = "EFA8CA"
            _suggestions.append(suggestion_1)
        }else{
            var suggestion_1 = suggestionsStruct()
            suggestion_1.title = "..."
            suggestion_1.text = "..."
            suggestion_1.firstColor = "C68CF2"
            suggestion_1.secondColor = "EFA8CA"
            _suggestions = [suggestion_1]
        }
        return _suggestions
    }
}

如果建议数据从未更改，则只需使用以下结构：

struct collectinView {
    let title: String
    let text: String
    let firstColor = "C68CF2"
    let secondColor = "EFA8CA"
}

let collectionViewData = [
    collectionView(title: "...", text: "..."),
    collectionView(title: "other Title", text: "Other text")]

Swift-计算属性返回
