Question

我收到一条内存警告：“对于标记行的challengeCell，”调用者此时不拥有的对象的引用计数的减少不正确。“

myIdentifier = @"ChallengTblVwCell";    
ChallengeTableViewCell *challengeCell = (ChallengeTableViewCell *)[tableView dequeueReusableCellWithIdentifier:myIdentifier];
if( challengeCell == nil )
{
    [[ NSBundle mainBundle ] loadNibNamed:@"ChallengeTableViewCell" owner:self options:nil ];
    challengeCell = challengeTblCell; 
}

else {
//some code
}           
        challengeInstance = [genericArray objectAtIndex:indexPath.row];
        NSString *challengeTitle = challengeInstance.elecompany;

        [challengeCell initWithTitle:challengeTitle subTitle:challengeSubtitle _votes:challengeVotes content:challengeContent _time:challengeTime _image:challengeImage noComments:challengeCommentsNo]; //Warning coming at this line
        return (UITableViewCell *)challengeCell;

编辑：

 -(id)initWithTitle:(NSString *)_title content:(NSString *)_content fromName:(NSString *)_fromName _time:(NSString *)_time_ _image:(NSString *)_image_ noComments:(NSInteger)commentsNo
 {
    //Labels are created through interface builder

[_lbltitle_ setText:_title];       
[_lbltime setText:_time_];
[lblcontent setText:_content];
[lblsubTitle setText:_fromName];
[lblnoOfComments setText:[NSString stringWithFormat:@"%d",commentsNo]];

// code for adjusting label height according to content.

return self;
}

我将这个单独的类用于管理单元格以使其操作变得容易。

有人可以帮我解决这个问题吗？

提前完成。

如果你为这两行发布initWithTitle的代码会更好：

[challengeCell initWithTitle:challengeTitle subTitle:challengeSubtitle _votes:challengeVotes content:challengeContent _time:challengeTime _image:challengeImage noComments:challengeCommentsNo]; //Warning coming at this line
return (UITableViewCell *)challengeCell;

但我猜你已经拥有一个challengeCell对象，已经分配并初始化了。说实话，你的代码看起来很奇怪。通常，人们所做的事情[[UIChallengeCell alloc] initWithTitle...]不是来自实例本身。我认为这会产生你的问题。

您应该做的是自己设置属性。

challengeCell.challengeTitle = challengeTitle;
challengeCell.subTitle = challengeSubtitle;
