我有一個UITableView,有20行並且在每一行中我都有1個UIImageView,4個UITextView和3個UIButton。UIScrollView中的UIButton顏色在滾動時設置爲錯誤的顏色
我的tablview加載完美,但是當我滾動時,一些UIBUtton顯示錯誤的顏色。例如 只有一行應該有黃色的UIColor,但是當我滾動另一行時的另一個解除按鈕變成黃色!
這裏是我的代碼:
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
var cell:TimelineTableViewCell? = tableView.dequeueReusableCellWithIdentifier("TimelineTableViewCell") as? TimelineTableViewCell
if (cell == nil){
cell = NSBundle.mainBundle().loadNibNamed("TimelineTableViewCell", owner: self, options: nil)[0] as? TimelineTableViewCell
}
cell!.nameLabel.text = self.userNameA[indexPath.row]
cell!.screenNameLabel.text = "@" + self.screenNameA[indexPath.row]
cell!.tweetLabel.text = self.tweetA[indexPath.row]
cell?.avatarImage.hnk_setImageFromURL(NSURL(string:self.avatarA[indexPath.row]))
cell?.avatarImage.layer.cornerRadius = 4
cell?.avatarImage.layer.masksToBounds = true
if langA[indexPath.row] == "fa" {
cell?.tweetLabel.textAlignment = NSTextAlignment.Right
} else if langA[indexPath.row] == "ar" {
cell?.tweetLabel.textAlignment = NSTextAlignment.Right
}
cell?.favButton.setTitle(favorite_countA[indexPath.row], forState: .Normal)
cell?.reTweetButton.setTitle(retweet_countA[indexPath.row], forState: .Normal)
if favoritedA[indexPath.row] {
cell?.favButton.setTitleColor("#FFE066".UIColor, forState: .Normal)
}
if retweetedA[indexPath.row] {
cell?.reTweetButton.setTitleColor("#70B894".UIColor, forState: .Normal)
}
cell?.reTweetButton.tag = indexPath.row;
cell?.reTweetButton.addTarget(self, action: "retweetPressed:", forControlEvents: UIControlEvents.TouchUpInside)
cell?.favButton.tag = indexPath.row;
cell?.favButton.addTarget(self, action: "favPressed:", forControlEvents: UIControlEvents.TouchUpInside)
return cell;
}
它只出現在的UIButton。那麼,怎麼了?
什麼是retweetedA? – 2014-10-16 15:20:12
@FawadMasud Bool值的數組,如果推文已被轉發,則返回true。 – 2014-10-16 15:32:51
我會建議在自定義單元格中創建bool屬性並像cell.retweetedA一樣訪問它們。這個問題似乎與滾動時單元格的索引有關。 – 2014-10-16 15:51:24
