经典标尺 样式

TTScrollRulerView *rulerClassic = [[TTScrollRulerView alloc] initWithFrame:CGRectMake(50, 50+100*0, cy_ScreenW-100, 100)];
[self.view addSubview:rulerClassic];
rulerClassic.rulerDelegate = self;
//在执行此方法前，可先设定参数：最小值，最大值，横向，纵向等等  ------若不设定，则按照默认值绘制
[rulerClassic classicRuler];

自定义标尺 样式

TTScrollRulerView *rulerCustom = [[TTScrollRulerView alloc] initWithFrame:CGRectMake(50, 50+100*1, cy_ScreenW-100, 100)];
[self.view addSubview:rulerCustom];
rulerCustom.rulerDelegate = self;
//在执行此方法前，可先设定参数：最小值，最大值，横向，纵向等等   ------若不设定，则按照默认值绘制
[rulerCustom customRulerWithLineColor:customColorMake(0, 0, 0) NumColor:[UIColor redColor] scrollEnable:YES];

横向滚动，刻度位于上方

TTScrollRulerView *rulerHUP = [[TTScrollRulerView alloc] initWithFrame:CGRectMake(50, 50+100*2, cy_ScreenW-100, 100)];
[self.view addSubview:rulerHUP];
rulerHUP.rulerDelegate = self;
//设置滚动方向，默认横向滚动
rulerHUP.rulerDirection = RulerDirectionHorizontal;
//设置刻度位置，默认在上方
rulerHUP.rulerFace = RulerFace_up_left;
[rulerHUP classicRuler];

横向滚动，刻度位于下方

TTScrollRulerView *rulerHDOWN = [[TTScrollRulerView alloc] initWithFrame:CGRectMake(50, 50+100*3, cy_ScreenW-100, 100)];
[self.view addSubview:rulerHDOWN];
rulerHDOWN.rulerDelegate = self;
//设置滚动方向，默认横向滚动
rulerHDOWN.rulerDirection = RulerDirectionHorizontal;
//设置刻度位置，下方
rulerHDOWN.rulerFace = RulerFace_down_right;
[rulerHDOWN classicRuler];

纵向滚动，刻度位于左边

TTScrollRulerView *rulerVUP = [[TTScrollRulerView alloc] initWithFrame:CGRectMake(50, 50+100*4, 100, 250)];
[self.view addSubview:rulerVUP];
rulerVUP.rulerDelegate = self;
//设置滚动方向，默认横向滚动
rulerVUP.rulerDirection = RulerDirectionVertical;
//设置刻度位置，下方
rulerVUP.rulerFace = RulerFace_up_left;
[rulerVUP classicRuler];

纵向滚动，刻度位于右边

TTScrollRulerView *rulerVDOWN = [[TTScrollRulerView alloc] initWithFrame:CGRectMake(50+100, 50+100*4, 100, 250)];
[self.view addSubview:rulerVDOWN];
rulerVDOWN.rulerDelegate = self;
//设置滚动方向，默认横向滚动
rulerVDOWN.rulerDirection = RulerDirectionVertical;
//设置刻度位置，下方
rulerVDOWN.rulerFace = RulerFace_down_right;
[rulerVDOWN classicRuler];

参数改变后，重新绘制标尺

rulerVDOWN.lockMin = 50;
[rulerVDOWN reDrawerRuler];

让标尺滚动到某一个数值

[rulerVDOWN scrollToValue:50 animation:NO];

完全自定义标尺

/**
 *  自定义标尺
 *  注意事项：
 *  1、标尺视图的frame需要足够标尺显示出来，自己摸索
 *  2、最小值、最大值、单位刻度值，最好一起设定，只设定部分会和默认值产生冲突
 *  3、默认值的意思是标尺创建之后，刻度所在的位置，若不设定，会默认在最小值的位置
 *  4、自定义指针的frame是相对于标尺视图的

 *  如果遇到其它问题，无法解决，请联系QQ：943051580
