Swift 如何发现字典数组中存在重复数据

swift dictionary

Swift 如何发现字典数组中存在重复数据,swift,dictionary,Swift,Dictionary,我有一组字典。如果字典数组中存在重复数据，则将使用重复的元素名称引发一个标志字典数组如下所示： [[project_code: 1, lob: lob_1], [project_code: 1, lob: lob_1], [project_code: 2, lob: lob_1], [project_code: 3, lob: lob_1]] 在这里，我们需要循环查找相同的项目\代码和lob是否相同，然后它将返回所有重复的项目\代码重复数据意味着项目代码和lob值对应该相同在上面的数组中

我有一组字典。如果字典数组中存在重复数据，则将使用重复的元素名称引发一个标志

字典数组如下所示：

[[project_code: 1, lob: lob_1], [project_code: 1, lob: lob_1], [project_code: 2, lob: lob_1], [project_code: 3, lob: lob_1]]

在这里，我们需要循环查找相同的项目\代码和lob是否相同，然后它将返回所有重复的项目\代码

重复数据意味着项目代码和lob值对应该相同

在上面的数组中，如果我们遍历，那么它应该返回project_代码：1

如果有人能用Swift写代码

提前谢谢。

使用

扩展名：

extension Array {
    var isContainedDuplicateData: Bool {
        for (var i = 0 ; i < self.count; ++i){
            for (var j = i+1 ; j < self.count; ++j){

                let p = self[i] as? NSDictionary
                let q = self[j] as? NSDictionary

                if (p  == q ){
                    return true
                }
            }
        }
        return false
    }
}

var duplicateData: AnyObject {

这需要一个自定义代码，您可以很容易地自己编写。循环遍历数组，并通过比较它们的对和提升标志将其与其他字典进行比较。没什么特别的。这需要一个自定义代码，你可以很容易地自己编写。循环遍历数组，并通过比较它们的对和提升标志将其与其他字典进行比较。没什么特别的。这需要一个自定义代码，你可以很容易地自己编写。循环遍历数组，并通过比较它们的对和提升标志将其与其他字典进行比较。没什么特别的。这需要一个自定义代码，你可以很容易地自己编写。循环遍历数组，并通过比较它们的对和提升标志将其与其他字典进行比较。没什么特别的。你能给我一个只检查项目代码而不检查lob的代码吗。情况依然如此。如果存在重复的项目代码，无论是否存在lob。。。它应该列出所有重复的项目代码。。提前谢谢你能给我一个只检查项目代码而不是lob的代码。情况依然如此。如果存在重复的项目代码，无论是否存在lob。。。它应该列出所有重复的项目代码。。提前谢谢你能给我一个只检查项目代码而不是lob的代码。情况依然如此。如果存在重复的项目代码，无论是否存在lob。。。它应该列出所有重复的项目代码。。提前谢谢你能给我一个只检查项目代码而不是lob的代码。情况依然如此。如果存在重复的项目代码，无论是否存在lob。。。它应该列出所有重复的项目代码。。提前谢谢
