TableViewController 使用 SDWebImage 和 UIImage [英] TableViewController using SDWebImage with UIImage

问题描述

下午好，

我第一次尝试在我的 TableViewController 中使用 SDWebImage，我在使用setImageWithURL"属性时遇到了一些问题，因为它只允许 UIImageView 但我有一个 UIImage 以便解析来自我的 JSON 的数据.

Im trying to use SDWebImage in my TableViewController for the first time and I have some problems using the "setImageWithURL" property because it only admits a UIImageView but I have a UIImage in order to parse the data from my JSON.

我必须如何更改代码才能使用 UIImageView 而不是 UIImage?因为 UIImageView 没有与 UIImage 相同的功能，所以我必须从 URL 创建我的图像.

How I have to change my code in order to use a UIImageView instead of a UIImage? Because UIImageView doesn't have the same functions as UIImage and I have to create my Image from a URL.

这是我的代码，希望你能帮我一些提示:

Here is my code, I hope you can help me with some tips:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{
    static NSString *CellIdentifier = @"carTableCell";
    CarTableViewCell *cell = [tableView

                              dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[CarTableViewCell alloc]
                initWithStyle:UITableViewCellStyleDefault
                reuseIdentifier:CellIdentifier];
    }
    // Configure the cell...

    cell.makeLabel.text = [[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"id"];
    cell.likes.text = [[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"likes"];
    cell.comments.text = [[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"comments"];
    cell.username.text = [[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"username"];
    cell.refuser.text = [[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"user_ref"];
    cell.modelLabel.text = [[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"user"];

    NSURL * imageURL = [NSURL URLWithString:[[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"imagen"]];
    NSData * imageData = [NSData dataWithContentsOfURL:imageURL];
    UIImage * carPhoto = [UIImage imageWithData:imageData];
    cell.carImage.image = carPhoto;

    /*[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
               placeholderImage:[UIImage imageNamed:@"placeholder.png"]];*/

    NSURL * imageURL2 = [NSURL URLWithString:[[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"image"]];
    NSData * imageData2 = [NSData dataWithContentsOfURL:imageURL2];
    UIImage * carPhoto2 = [UIImage imageWithData:imageData2];
    cell.profileImage.image = carPhoto2;

    return cell;

}

非常感谢.

推荐答案

当你使用SDWebImage

[cell.carImage sd_setImageWithURL: [NSURL URLWithString: imageURL]];
[cell.profileImage sd_setImageWithURL: [NSURL URLWithString: imageURL2]];

并删除下面的行

NSURL * imageURL = [NSURL URLWithString:[[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"imagen"]];
NSData * imageData = [NSData dataWithContentsOfURL:imageURL];
UIImage * carPhoto = [UIImage imageWithData:imageData];
cell.carImage.image = carPhoto;

/*[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
           placeholderImage:[UIImage imageNamed:@"placeholder.png"]];*/

NSURL * imageURL2 = [NSURL URLWithString:[[_jsonArray objectAtIndex:indexPath.row] valueForKey:@"image"]];
NSData * imageData2 = [NSData dataWithContentsOfURL:imageURL2];
UIImage * carPhoto2 = [UIImage imageWithData:imageData2];
cell.profileImage.image = carPhoto2;
