iPhone SDK - 問題從RSS源解析XML

Question

我做了一個RSS閱讀器，從blogspot獲取一個feed。 從故事，標題等文本工作正常。 但是，Feed中顯示的圖像顯示爲鏈接而不是圖像。 如何顯示圖像？

Answer 1

下面是一些代碼，我用動態圖像下載到一個列表：

//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]; 
} 

希望它能幫助，祝你好運！
