Question

我正在尝试初始设置UITableViewCell将显示单元格，但它不起作用。谁能帮助我？

-(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *) cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
     cell.awtxt.font = [UIFont fontWithName:@"Helvetica" size:15.0]; //i am unable to set this .awtxt is the property outlet in my custom ui table view cell named as "postCell"
}

对我而言，当我将方法从UITableViewCell更改为我的自定义单元格时，它才有用。因此，只需将UITableViewCell替换为您的自定义postCell

即可

 -(void) tableView:(UITableView *)tableView willDisplayCell:(postTableViewCell *) cell forRowAtIndexPath:(NSIndexPath *)indexPath // replace "postTableViewCell" with your cell
 {

  cell.awtxt.font = [UIFont fontWithName:@"Helvetica" size:15.0]; //i am unable to set this .awtxt is the property outlet in my custom ui table view cell named as "postCell"

 }

我同意Mike_NotGuilty。我尝试了他建议的UITableViewCell的自定义/子类，称为BNRItemCell，方法定义如下，并且效果很好：

//This function is where all the magic happens
-(void) tableView:(UITableView *) tableView willDisplayCell:(BNRItemCell *) cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Set the cells background color
    if (indexPath.row % 2 == 0) {
        UIColor *altCellColor = [UIColor colorWithWhite:0.3 alpha:0.5];
        cell.backgroundColor = altCellColor;
    }

    [UIView beginAnimations:@"fade" context:nil];
    [UIView setAnimationDuration:20.0];
    [UIView setAnimationRepeatAutoreverses:YES];
    [UIView setAnimationRepeatCount: 0.5];
    [cell.nameLabel setAlpha:0.4];
    [cell.nameLabel setAlpha:1];
    [UIView commitAnimations];
}

您应该使用自定义方法替换原始方法定义，然后尝试：

-(void) tableView:(UITableView *) tableView willDisplayCell:(PostCell *) cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    // your code here
}

如何在willDisplayCell方法中配置UITableViewCell？
