我正在将otherUserUid和otherUserFullName推送到另一个视图控制器,但它没有被立即调用 . 信息滞后,需要2次点击才能显示信息 .
我认为preparForSegue:在didSelectRowAtIndexPath之前被调用:任何解决方案如何解决这个问题?
干杯!
override func tableView(tableView:UITableView,didSelectRowAtIndexPath indexPath:NSIndexPath){
self.performSegueWithIdentifier("jsqDirectory", sender: self)
let indexPath = tableView.indexPathForSelectedRow!
let currentCell = tableView.cellForRowAtIndexPath(indexPath)! as UITableViewCell
self.otherUserFullName = (currentCell.textLabel?.text)!
print(self.otherUserFullName)
self.otherUserUid = (currentCell.detailTextLabel?.text)!
print(self.otherUserUid)
}
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if segue.identifier == "jsqDirectory" {
if let viewController = segue.destinationViewController as? JSQViewController{
viewController.senderDisplayName = self.fullName
viewController.senderId = self.firebase.authData.uid
viewController.otherUid = self.otherUserUid
viewController.otherUser = self.otherUserFullName
}
}
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("directoryCell") as UITableViewCell!
let directoryItem = items[indexPath.row]
cell.textLabel?.text = directoryItem.fullName
cell.detailTextLabel!.text = directoryItem.key
cell.detailTextLabel!.hidden = true
return cell
}

在didSelectRowAtIndexPath中你必须在函数结束时执行segue,就像这样..
