我想创建一个简单的应用程序,我想在其中创建一个持续动画的道路。我怎么能这样做?
答案 0 :(得分:1)
我使用了UIScrollView。然后,设置运行以下内容的NSTimer:
-(void)scroll{
CGPoint currentPoint = playerStatsRect.contentOffset;
CGPoint scrollPoint = CGPointMake(currentPoint.x, currentPoint.y + 1);
[playerStatsRect setContentOffset:scrollPoint animated:NO];
if(scrollPoint.y == playerStatsRect.contentSize.height+5)//If we've reached the bottom, reset slightly past top, to give ticker look
{
[playerStatsRect setContentOffset:CGPointMake (0,-125)];
}
}
希望这会有所帮助:)
