ios - 出现错误 [UIImage mutableCopyWithZone :]: unrecognized selector sent to instance

Question

处理 JSON 数据并从字典中提取图像并将图像添加到数组

  NSURL *imageurl=[NSURL URLWithString:(NSString *) Dictionry[@"product"][@"image_medium_url"]];
    NSData *data = [NSData dataWithContentsOfURL:imageurl];
    UIImage *image = [UIImage imageWithData:data];
    [self.productImageArray addObject:image];

我正在将这个数组复制到另一个数组

for(int i=0;i<prodReq.productNameArray.count;i++)
{

    [productimageA addObject:[[prodReq.productImageArray objectAtIndex:i] mutableCopy]];
}

并将图像设置为 ImageView

UIImageView *productimage=[[UIImageView alloc]initWithFrame:CGRectMake(15, prodimgY, 60, 75 )];
    productimage.image=[productimageA objectAtIndex:indexPath.row];

当我运行这个项目时出现这个错误

 -[UIImage mutableCopyWithZone:]: unrecognized selector sent to instance 0x14581240

有什么问题吗？

Answer 1

您正在将 UIImage 添加到 productImageArray。您不需要为 UIImage 对象添加 mutableCopy。所以就用

[productimageA addObject:[prodReq.productImageArray objectAtIndex:i] ];
