UIScrollView抵消内容加倍请求的金额

Question

问题

我的PSWSnapshotView最终在_scrollView（40px偏移）内向右移得太远了。然而，它们的框架设置为第一个在（0,0），但第一个显示在（snapshotInset，0）而不是：/。

守则

- (void)layoutViews
{
    CGRect frame = self.frame;
    CGFloat pageWidth = frame.size.width - (snapshotInset * 2);
    CGRect pageFrame = CGRectMake(0.0f, 0.0f, pageWidth, frame.size.height);
    NSInteger pageCount = [applications count];

    [pageControl setNumberOfPages:pageCount];
    [scrollView setFrame:CGRectMake(snapshotInset, 0.0f, pageWidth, frame.size.height)];
    [scrollView setContentSize:CGSizeMake((pageWidth * pageCount) + 1.0f, frame.size.height)];

    for (int i = 0; i < pageCount; i++) {
        PSWSnapshotView *view;
        if ([snapshotViews count] <= i)
        {
            PSWSnapshotView *view = [[PSWSnapshotView alloc] initWithFrame:pageFrame application:[applications objectAtIndex:i]];
            view.delegate = self;
            [scrollView addSubview:view];
            [snapshotViews addObject:view];
            [view release];
        }
        else
        {
            view = [snapshotViews objectAtIndex:i];
            [view setFrame:pageFrame];
        }

        pageFrame.origin.x += pageWidth;
    }
}

值

self.frame.size.width = 320; self.frame.size.height = 370; snapshotInset = 40; [申请数] = 2;

所有尺寸和框架都设置正确（我用NSLog检查过）。

您是否可以在某处设置scrollView.contentOffset，与此无关？此外，这可能只是一个复制/粘贴问题，您同时引用snapshotInset和_snapshotInset。
