Question

i 在电话桌旁有以下几行,有时从一个行向另一个行泄。

if (row <1)
    {
        cell.detailTextLabel.text=@"h3ello";
             UIImage *image = [UIImage imageNamed:@"icon.png"];
           cell.imageView.image = image;   
    }
      else if (row ==2)
    {
        cell.detailTextLabel.text=@"world";
        UIImage *image = [UIImage imageNamed:@"ticon.png"];
        cell.imageView.image = image
}

有时,这些图像被混为一谈,而且有另一行,包括文字颜色。造成各种随机浏览,一味.。不能确定错误是什么。

EDIT

这是所涉罪犯。

 cell.textLabel.textColor = [UIColor redColor];

once i remove this none of the rows get mixed up with the colors. how can i implement this color to a specific row without it leaking onto the others randomly.

Answer 1

Because cells by default are reusable you should always set ALL parameters for ALL cells you ever used. If you want to change color for one cell you should set default color for OTHER cells too. So use cell.textLabel.textColor = .... in each case with proper color.

Answer 2

“天空”是正确的。让我澄清一点:

cell.textLabel.text = @"";
cell.textLabel.textColor = [UIColor clearColor];
cell.imageView.image = nil;

if (row <1)
{
    cell.detailTextLabel.text=@"h3ello";
    UIImage *image = [UIImage imageNamed:@"icon.png"];
    cell.imageView.image = image;   
}
  else if (row ==2)
{
    cell.detailTextLabel.text=@"world";
    UIImage *image = [UIImage imageNamed:@"ticon.png"];
    cell.imageView.image = image
} else {
}
