我做了一个RSS阅读器,从blogspot获取一个feed。 从故事,标题等文本工作正常。 但是,Feed中显示的图像显示为链接而不是图像。 如何显示图像?iPhone SDK - 问题从RSS源解析XML

你可以发布样本XML或给链接到XML文件? – Saurabh 2010-09-10 17:14:52

下面是一些代码,我用动态图像下载到一个列表:

//starts the downloading of the image 
- (void) downloadImage 
{ 
    [NSThread detachNewThreadSelector:@selector(imageDownloadWorker:) 
          toTarget:self 
          withObject:[self getAvatarUrl]/*here goes your url*/]; 
} 

//does something with the image once loaded 
- (void)imageLoaded:(UIImage *)image 
{ 
    //do something 
} 

//downloads the image 
- (void)imageDownloadWorker:(NSString *)urlString 
{ 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
    NSURL    *url = [NSURL URLWithString:urlString]; 
    NSData   *data = [NSData dataWithContentsOfURL:url]; 
    UIImage   *image = [[UIImage alloc] initWithData:data]; 

    [self performSelectorOnMainThread:@selector(imageLoaded:) 
          withObject:[image autorelease] 
         waitUntilDone:YES]; 
    [pool drain]; 
} 

希望它能帮助,祝你好运!
