在这个例程中 - tableView validateDrop,我需要了解返回的项目。返回项目数组似乎是文件ID?查找器URL解释
func tableView(tableView: NSTableView, validateDrop info: NSDraggingInfo,
proposedRow row: Int, proposedDropOperation dropOperation: NSTableViewDropOperation) -> NSDragOperation {
print("validate drop \(dropOperation)")
if dropOperation == .Above {
//get the file URLs from the pasteboard
let pasteboard = info.draggingPasteboard()
//list the file type UTIs we want to accept
let options = [NSPasteboardURLReadingFileURLsOnlyKey : true,
NSPasteboardURLReadingContentsConformToTypesKey : [kUTTypeMovie as String]]
let items = pasteboard.readObjectsForClasses([NSURL.classForCoder()],
options: options)
if items!.count > 0 {
for item in items! {
print("item -> \(item)")
}
print("validate Above -> .Copy")
return .Copy;
} else {
print("validate Above -> .Move")
return .Move
}
}
print("validate other -> .None")
return .None
}
,输出:
item -> file:///.file/id=6571367.34508463
在某些时候,我需要这个翻译成什么,我可以使用 - 典型的文件:// URL格式。
