当阵列中的多个图像

Question

我有一个UIScrollview用于分页和缩放图像，当我在我的阵列中有一个图像时，它正在变焦，否则缩放会以奇怪的方式表现。分页很好。我有几天在苦苦挣扎，请帮助一下。我对UIScrollview不熟悉。感谢。

    -(void) settingScroll{
        int xx,yy,im_xx,im_yy,im_Wt,im_ht;

            CGRect screenRect = [[UIScreen mainScreen] bounds];
            xx      = screenRect.size.width;
            yy      = 452;
            im_xx   = 0;
            im_yy   = 0;
            im_Wt   = screenRect.size.width;
            im_ht   = 452;


            scxx =0;

            for(int i=0;i<[totalArray_menu count];i++)
            {
                scroll = [[UIScrollView alloc]initWithFrame:CGRectMake(scxx, 0, xx, yy)];

               [img2 setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",initial_server_address,[totalArray_menu objectAtIndex:i]]]];

                img2.backgroundColor=[UIColor lightTextColor];
                [scroll addSubview:img2];
                [self.popUpImageScrollView2 addSubview: scroll];
                scxx+=xx;
            }

        cntSizX=scxx;
        self.popUpImageScrollView2.tag = 456;
        self.popUpImageScrollView2.contentSize        = CGSizeMake(cntSizX,yy);

        self.popUpImageScrollView2.backgroundColor    = [UIColor clearColor];
        self.popUpImageScrollView2.pagingEnabled      = YES;

        self.popUpImageScrollView2.showsHorizontalScrollIndicator = NO;
        self.popUpImageScrollView2.showsVerticalScrollIndicator = NO;

        self.popUpImageScrollView2.bounces=YES;
        scxx=xx;
        [self.popUpImageScrollView2 setContentOffset:CGPointMake(scxx*tag,0) animated:NO];
        [self.popUpImageView2 addSubview:self.popUpImageScrollView2];
}
