//将下载的图片循环存入图片的数组中

for ( int i = 0 ; i<count; i++)

{

//picarray为存放图片路径的数组

NSString * str = [picArray objectAtIndex:i];

NSURL * url_josna=[NSURL URLWithString:str];

NSURLRequest * request =[NSURLRequest requestWithURL:url_josna cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:10.0f];

//发送同步请求得到的数据

NSData * data=[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

//self.p_w_picpath为属性

self.p_w_picpath = [UIImage p_w_picpathWithData:data];

[p_w_picpathdataArray addObject:self.p_w_picpath];

}

//将图片从数组取出循环贴在scroview上

for (int i = 0; i<count; i++)

{

NSLog(@"%d",i);

UIImageView * p_w_picpatha = [[UIImageView alloc] initWithFrame:CGRectMake(320*i, 0, 320, 480)];

[p_w_picpatha setImage:[p_w_picpathdataArray objectAtIndex:i]];

NSLog(@"%@",[p_w_picpathdataArray objectAtIndex:i]);

[scro addSubview:p_w_picpatha];

[p_w_picpatha release];

}
