如何使用UISlider以及如何在特定值上设置滑块? [英] how to use the UISlider and how to set the slider on a particular values?

问题描述

我第一次使用UIslider. 首先，我想知道如果值的范围是0到10，如何对滑块正值进行门控:

i am using an UIslider first time. first i want to know how to gat value of slider positon if the range of value is 0 to 10:

第二秒，我希望将滑块设置为5个不同的值. 像1，2，3，4，5

second i want my slider just set at 5 different values . like 1, 2, 3, 4, 5

滑块不应在标签值之间设置

slider should not set between the labeled value

I followed this tutorial for mine and it was very helpful there are variables you can set in the code such as max number and how much the slider increases each time. Link: http://www.xprogress.com/post-35-uislider-tutorial-example-how-to-use-slider-in-iphone-sdk-xcode/
