iphone - 为什么我无法在屏幕上查看图像？

-(void)parser:(NSXMLParser *)parser
didEndElement:(NSString *) elementName
 namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName{

    if ([elementName isEqual:@"image"]) {

        NSLog(@"Encoded Data %@",encodedData); //THIS SHOWS UP FINE
        //lets now show image

        UIImage * decodedImage = [[UIImage alloc] initWithData:[Base64 decode:encodedData]];
        [Image setImage:decodedImage]; //WHERE IS THE IMAGE?
        [encodedData release];
        encodedData = nil;
    }
}

我正在使用以下库进行base 64解码。

最佳答案

-(void)parser:(NSXMLParser *)parser
didEndElement:(NSString *) elementName
 namespaceURI:(NSString *)namespaceURI
qualifiedName:(NSString *)qName {

    if ([elementName isEqual:@"image"]) {

        NSLog(@"Encoded Data %@",encodedData); //THIS SHOWS UP FINE
        //lets now show image

        UIImage * decodedImage = [[UIImage alloc] initWithData:[Base64 decode:encodedData]];
        [yourImageView setImage:decodedImage]; //WHERE IS THE IMAGE?
        //Make sure that you have the imageView added as subview to your current view.
        [encodedData release];
        encodedData = nil;
        [decodedImage release];
    }
}
