使单元出队时对成员“ tableView”的不明确引用

Question

I'm running into an odd error. This line of code functions correctly:

let cell = self.tableView.dequeueReusableCellWithIdentifier("FeedCell", forIndexPath: indexPath) as UITableViewCell!

However when I cast to FeedCell! (a subclass of UITableViewCell ):

let cell = self.tableView.dequeueReusableCellWithIdentifier("FeedCell", forIndexPath: indexPath) as FeedCell!

Xcode throws the error: Ambiguous reference to member 'tableView'

I'm not sure how it can be ambiguous, let alone triggered by a different casting!

Answer 1

Try changing the line to

let cell = tableView.dequeueReusableCellWithIdentifier("FeedCell", forIndexPath: indexPath) as! FeedCell

Just remove the ! from FeedCell! and put it in as! and check if there is any difference.

Beside as @redent84 mentioned in his comment you should use tableView instead of self.tableView .
