如何在UIScrollView中显示4个不同的视频

Question

我希望一次在UIScrollView内显示4种不同的动画，所有动画都有200多帧，所以我认为解决此问题的最佳解决方案是显示视频。它比动画花费更少的内存。我的视频尺寸约为500x300，我希望将它们显示为250x150。我怎么能这样做？

这必须是你问题的解决方案

 - (void)layoutScrollImages
{
UIView *view = nil;
NSArray *subviews = [self.scrollView subviews];

// reposition all image subviews in a horizontal serial fashion
CGFloat curXLoc = 0;
for (view in subviews)
{
    if ([view isKindOfClass:[UIView class]] && view.tag > 0)
    {
        CGRect frame = view.frame;
        frame.origin = CGPointMake(curXLoc, 0);
        view.frame = frame;

        curXLoc += (kScrollObjWidth);
    }
}

// set the content size so it can be scrollable
//[self.scrollView setContentSize:CGSizeMake((numImages * kScrollObjWidth),    [self.scrollView bounds].size.height)];

[self.scrollView setContentSize:CGSizeMake((numImages * kScrollObjWidth), kScrollObjHeight)];
