Answer 1

您可以使用imageWithData中的UIImage。像，

UIImage *image =[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:imageName]]];

Answer 2

你的编码很好

更改此行

NSString *imageName = [NSString stringWithFormat:@"%@UploadedImages/%@",appDel.serverUrl,[[sCatArray objectAtIndex:indexPath.row] objectForKey:@"SubCategoryIcon"]];

进入bz ur URL包含/UploadedImages/

NSString *imageName = [NSString stringWithFormat:@"%@/UploadedImages/%@",appDel.serverUrl,[[sCatArray objectAtIndex:indexPath.row] objectForKey:@"SubCategoryIcon"]];

yourimageName.image =[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:imageName]]];

你需要快速加载UIImage吗？

1. Asynchronous FreeLoader

2. SDWebImage

当我在浏览器中尝试您的图片时，它显示错误，因此请检查一次path is valid or not否则your image name is valid or not

试试这个：

NSString *imageName = [NSString stringWithFormat:@"%@UploadedImages/%@",appDel.serverUrl,[[sCatArray objectAtIndex:indexPath.row] objectForKey:@"SubCategoryIcon"]];
UIImage *imgObj = [UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString:imageName]]];
_yourImgView.image=imgObj;
