更快速地从URL加载图像并将其显示在iPhone应用程序中 [英] Faster way to load an image from a URL and display it in an iPhone app

问题描述

我使用以下代码在我的ImageView中显示图像：

I am using the following code to display an image in my ImageView:

   imgbackBG.image = [UIImage imageWithData:
                   [NSData dataWithContentsOfURL:
                    [NSURL URLWithString:[NSString stringWithFormat:@"http://%@",    [test.arrImagessplash objectAtIndex:[test.arrImages count]-4]]]]];

    4cing.com/mobile_app/uploads/pageicon/splash.png

问题是代码执行速度非常慢。有没有办法加载图像并更快地在ImageView中显示它？如果是这样，我该怎么做？

The problem is that the code executes very slowly. Is there a way to load the image and display it in the ImageView more quickly? If so, how can I do this?

[asyncImageView loadImageFromURL:[NSURL URLWithString:your url]];
[YourImageView addSubview:asyncImageView];
[asyncImageView release];
