iOS 异步加载图片 使用EGOImageView、SDWebImage按步骤使用的，就是不能显示图片

EGOImageView *egoView = [[EGOImageView alloc]initWithPlaceholderImage:[UIImage imageNamed:@"user_head_img"]];

egoView.frame = CGRectMake(10 + 100 * x, 10 + 100 * y, 90, 90);

egoView.imageURL = [NSURL URLWithString:imagePath];
[self.scrollView addSubview:egoView];
／／
UIImageView *imgView = [[UIImageView alloc]initWithFrame:CGRectMake(10 + 100 * x, 10 + 100 * y, 90, 90)];

[imgView setImageWithURL:[NSURL URLWithString:imagePath] placeholderImage:[UIImage imageNamed:@"user_head_img"]];
[self.scrollView addSubview:imgView];
／／这两段代码都不行！！！
当我用UIWebView时，就可以正常使用，但是，这不是异步加载呀！
UIWebView *imageView = [[UIWebView alloc]init];

imageView.scalesPageToFit=YES;

NSURL *contentViewUrl = [NSURL URLWithString:imagePath];

NSURLRequest *request = [NSURLRequest requestWithURL:contentViewUrl];

[imageView loadRequest:request];

imageView.frame = CGRectMake(10 + 100 * x, 10 + 100 * y, 90, 90);

用多线程可以实现。
