我收到了CGSUpdateManager警告，该警告是在用户按下＆＃34;导入＆＃34;后，我从NSOpenPanel完成处理程序中显示我的视图控制器大约10秒后发生的。 我触发视图控制器的代码如下所示。
func ImportCSV() {
// Setup Panel
let fileType: [String] = ["csv", "CSV"]
var importPanel = NSOpenPanel()
importPanel.title = "Import"
importPanel.prompt = "Import"
importPanel.allowedFileTypes = fileType
importPanel.allowsMultipleSelection = false
importPanel.canChooseDirectories = false
importPanel.canCreateDirectories = false
importPanel.canChooseFiles = true
// Begin Panel
importPanel.beginWithCompletionHandler { (result) -> Void in
if result == NSFileHandlingPanelOKButton {
self.importFileWithURL(importPanel.URL!)
}
}
}
func importFileWithURL(URL: NSURL){
let storyBoard = NSStoryboard(name: "Main", bundle: nil)! as NSStoryboard
let importFileView = storyBoard.instantiateControllerWithIdentifier("test") as ImportFileViewController
self.presentViewControllerAsModalWindow(importFileView)
importFileView.fileToImport(URL)
}
我收到的警告是：

这个警告意味着什么，我应该担心吗？
