Answer 1

我完全不明白你的问题。这可以帮助你。

    UIScrollView *scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0.0, 0.0,1024,668)];
    scrollView.contentSize = CGSizeMake(1024,768);
    scrollView.delegate = self;
    scrollView.pagingEnabled = YES;
    scrollView.showsHorizontalScrollIndicator = YES;
    scrollView.showsVerticalScrollIndicator =YES;
    scrollView.alwaysBounceHorizontal = YES;
    scrollView.delaysContentTouches = NO;
    scrollView.canCancelContentTouches = NO;
    scrollView.bounces = YES;
    scrollView.bouncesZoom = YES;
    scrollView.scrollEnabled = YES;
    scrollView.directionalLockEnabled = YES;
    scrollView.minimumZoomScale = 0.5;
    scrollView.maximumZoomScale = 5.0;
    scrollView.scrollsToTop = YES;
    scrollView.backgroundColor=[UIColor clearColor];
    [self.view addSubview:scrollView];
