UIModalTransitionStyle有四种方式:

CoverVertical: 从底部升上来

CrossDissolve:快速闪现

FlipHorizontal:卡片翻转形式

PartialCurl:书本翻页效果

@IBAction func onShowInfo(sender: AnyObject) {

//实例化一个得分规则界面

let controller = InfoViewController(nibName: "InfoViewController",bundle: nil)

//规则界面出现的动画方式

controller.modalTransitionStyle = UIModalTransitionStyle.CoverVertical

//界面跳转

self.presentViewController(controller,animated:true,completion:nil)

}

@IBAction func onBack(sender: AnyObject) {

//移除自身(关闭当前界面,返回主界面)

self.dismissViewControllerAnimated(true,completion: nil)

}
