ios6 - 使用 If 循环填充 100 个图像

Question

我目前正在使用以下代码填充 100 张图像，但我确信使用 If 语句有一种更经济的方法：

mapblock01.image = [UIImage imageNamed:@"block.png"]; mapblock01.hidden = TRUE;
mapblock02.image = [UIImage imageNamed:@"block.png"]; mapblock02.hidden = TRUE;
mapblock03.image = [UIImage imageNamed:@"block.png"]; mapblock03.hidden = TRUE;
mapblock04.image = [UIImage imageNamed:@"block.png"]; mapblock04.hidden = TRUE;
mapblock05.image = [UIImage imageNamed:@"block.png"]; mapblock05.hidden = TRUE;

------>

mapblock99.image = [UIImage imageNamed:@"block.png"]; mapblock99.hidden = TRUE;
mapblock100.image = [UIImage imageNamed:@"block.png"]; mapblock100.hidden = TRUE;

有任何想法吗？

Answer 1

为此，您可以将每个 UIImageView 的标签指定为 1,2,3..100 并将图像设置如下：

  for (int i = 0 ; i < 100 ; i++) {
      UIImageView *imageV = (UIImageView *)[self.view viewWithTag:i];
      imageV.image = [UIImage imageNamed:@"block.png"];
      imageV.hidden = TRUE;
}
