Alerts

    var alert = NSAlert()    alert.messageText = 'Warning!"    alert.informativeText = "Hehe"    alert.alertStyle = NSAlertStyle.CirticalAlertStyle    alert.showSuppressionButton = true    alert.suppresionButton?.title = "No more"    alert.runModal()

从对话框获取反馈

    alert.addButtonWithTitle("Ignore it")    alert.addButtonWithTitle("Do noting")    let choice = alert.runModal()    switch choice{        case NSAlertFirstButtonReturn:        ...    }    if alert.suppressionButton!.state == 1{        print("checked")    }

将对话框平铺在window中

    let myCode = {        (choice:NSModalResponse) -> Void in         switch choice{            case NSAlertFirstButtonReturn:            ...        }        if alert.suppressionButton!.state == 1{            print("checked")        }    }    alert.beginSheetModalForWindow(window,completionHandler:myCode)
