使用Afnetworking获取UIImageView并将其放入数组中 [英] Get UIImageView using Afnetworking and put it in an array

问题描述

正如标题所说，我需要获取图像并将其放入数组中。

As the title says, i need to get the image and put it in an array.

UIImageView *myImage = [[UIImageView alloc] init];
[myImage setImageWithURL:[NSURL URLWithString:@"http://host.com/images/1/1.png"] placeholderImage:[UIImage imageNamed:@"page3.png"]];
[items addObject:myImage]; 

问题是在加载图像时，代码会继续，并且没有任何内容放入数组中，实际上我猜一个空的UIImageView被插入。

the problem is that while the image is being loaded, the code continues and nothing gets put in the array, actually I guess an empty UIImageView gets inserted.

如何修复此问题？

在旁注上我使用iCarousel来显示图像，在数据源中，它获取图像数组并显示它们。我能以某种方式修改iCarousel吗？

On a side note I am using iCarousel to display images, in the data source it gets the images array and shows them. Can i modify iCarousel somehow?

提前致谢。

推荐答案

您可以使用setImageWithURLRequest方法提供成功消息，或者在完成后执行UI更新，例如使用以下方法：

You can use the setImageWithURLRequest method to give a success message or execute the UI update when it has finished for example using the following method:

- (void)setImageWithURLRequest:(NSURLRequest *)urlRequest 
          placeholderImage:(UIImage *)placeholderImage 
                   success:(void (^)(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image))success
                   failure:(void (^)(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error))failure;

这是一个例子（未经测试）

Here is an example (not tested)

[image setImageWithURLRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"host.com/images/1/1.png"]] placeholderImage:[UIImage imageNamed:@"page3.png"] 
                   success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){ 
                             //reload data here
                   }
                   failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){
                             //handle errors here
                   }
