Question

在我的应用程序中，我使用自定义tableviewcell在一个单元格中加载两个图像，我的问题是当我第一次在我的视图上加载图像时，它显示了交换图像（第二张图像中的第一张图像和第一张图像中的第二张图像）然后在几分之一秒后加载适当的图像（第1张第1张和第2张图片第2张）。我正在使用AsyncImageView类来显示图像。每次第一次查看加载它显示错误，然后每次都正确。请帮帮我。

在CellForRow

AsyncImageView *imageView = [[AsyncImageView alloc] initWithFrame:celllookAlik.btnFullImg.frame];
imageView.contentMode = UIViewContentModeScaleAspectFill;
imageView.clipsToBounds = YES;
imageView.tag = IMAGE_VIEW_TAG1;
[celllookAlik addSubview:imageView];

AsyncImageView *imageViewll = [[AsyncImageView alloc] initWithFrame:celllookAlik.lookAlikeImage.frame];
imageViewll.contentMode = UIViewContentModeScaleAspectFill;
imageViewll.clipsToBounds = YES;
imageViewll.tag = IMAGE_VIEW_TAG2;
[celllookAlik addSubview:imageViewll];

使用以下代码在单元格中显示图片：

NSString * imageImage = @"";
imageImage = [[self.arrayResponseLookAlike objectAtIndex:indexPath.row] objectForKey:@"ImagePath"];

AsyncImageView *imageViewCelebrity = (AsyncImageView *)[celllookAlik viewWithTag:IMAGE_VIEW_TAG1];

//cancel loading previous image for cell
[[AsyncImageLoader sharedLoader] cancelLoadingImagesForTarget:imageViewCelebrity];

//load the image
imageViewCelebrity.imageURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@",imageImage]];

NSString * imageImageceleb = @"";
imageImageceleb = [[self.arrayResponseLookAlike objectAtIndex:indexPath.row ] objectForKey:@"LookLikeImage"];


AsyncImageView *imageViewllTemp = (AsyncImageView *)[celllookAlik viewWithTag:IMAGE_VIEW_TAG2];

//cancel loading previous image for cell
[[AsyncImageLoader sharedLoader] cancelLoadingImagesForTarget:imageViewllTemp];

//load the image
imageViewll.imageURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@",imageImageceleb]];

我遇到过这类问题，我使用过SDWebImage.frameword。这种框架集成非常简单，它可以正确加载图像。

首先，我们需要创建UIImageView来代替AsyncImageView。

使用以下代码在单元格中显示图片：

   [mMainImgView setImageWithURL:[NSURL URLWithString:loImgurl] placeholderImage:[UIImage imageNamed:@"placeholder"]];
