ios - 从对象数组中删除实际可见元素

Question

我有代码:

struct FilesToDownload {
    var fileInternetUrl: String?
    var fileName: String?
    var savedURL: String?
    var productImageUrl: URL?
    var fileSize: Int
}


var filesToDownload = [FilesToDownload]()


func startDownloadFiles(filesArray: [FilesToDownload], filesType: Int){
        for files in filesArray{
            print("- files.fileName")
            // here remove element files.fileName from array  filesToDownload
        }
    }

如何从 startDownloadFiles 数组中删除当前显示的元素 files.fileName？

Answer 1

很简单，您必须在 filesToDownload 数组中找到与 files.fileName 匹配的对象索引，然后从该索引中删除元素

 if let index = filesToDownload.index(where: {$0.fileName.lowercased() == files.fileName.lowercased() }) {
     filesToDownload.remove(at:index)     
  }
