获取当前时间
void Start () {
string nowTime = DateTime.Now.ToString("yyyy-MM-dd HH: mm: ss");
string nowTime1 = DateTime.Now.ToString("yyyy-MM-dd-HH-mm-ss");
print(nowTime);
print(nowTime1);
}
public Image image;
public ScrollRect scrollRect;
void Awake() {
//不规则按钮点击
image.alphaHitTestMinimumThreshold = 0.1f;
//alpha阈值指定一个像素必须具有的最小alpha，以便事件被视为图像上的“命中”。
//当alpha小于赋值的值0.1的的时候，图片无法进行点击检测
实现点击不规则按钮功能时（image.alphaHitTestMinimumThreshold = 0.1f）需要将图片设置如下：（在Advanced 下勾选 Read/Write Enabled ）
//ScrollView 界面初始化
scrollRect.verticalNormalizedPosition = 1;
//垂直滚动位置，值介于0和1之间，0位于底部。
//scrollView 的垂直滚动，可用于初始化scrollView的垂直展示
