// 按钮点击事件

func onTouchUpInside() {

struct touchUpInside {

static var count: Int = 0

}

touchUpInside.count += 1

print(touchUpInside.count)

if touchUpInside.count % 2 == 0 {

newsView.frame = CGRectMake(10, 22, UIScreen.mainScreen().bounds.size.width - 50, 40)

} else {

newsView.frame = CGRectMake(10, 22, UIScreen.mainScreen().bounds.size.width - 50, UIScreen.mainScreen().bounds.size.height - 20)

}
