NSString *urlString = @"http://img4.bitauto.com/autoalbum/files/20100226/003/201002260944098032_1155951_4.jpg";NSURL *url = [NSURL URLWithString:urlString];NSData *myData = [NSData dataWithContentsOfURL: url];UIImage *myImage = [UIImage imageWithData: myData];UIImageView *myImageView = [[UIImageView alloc] initWithImage: myImage];UIScrollView *myScrollView = [[UIScrollView alloc] initWithFrame: CGRectMake(0, 0, 320, 480)];myScrollView.contentSize = CGSizeMake(myImage.size.width, myImage.size.height;[self.view addSubview: myScrollView];[myScrollView release];[myScrollView addSubview: myImageView];[myImageView release];如果返回url是nil，則用下面的代碼代替：NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
