CircularSlider | A powerful Circular Slider | iOS library

I think a better approach is to first figure out what direction the user moved. This can be done by checking which direction has the closest distance between the new and the old position. Care must be taken to check for passing the border. Then it is a simple matter of adjusting the delta depending on direction.

My solution code assumes the the slider starts at zero, which I would recommend you to use instead of 1, since calculations are easier. If you really want to start at 1 it can be adjusted. I also have defined the maximum value as a constant SLIDER_MAX_VALUE, which you could change to a variable instead. Finally, I changed self.number to a CGFloat, so do the cast when using the number instead. This is important, otherwise you get rounding errors when sliding. If you really want an integer, use two variables, and assign the integer variable from the float.

You instantiate a new button every time you access btnNext. So after adding one instance as a subview you use other instances for creating the constraints. Since those other subviews are no subviews of self the app crashes.

Make it a lazy var to instantiate it only once:

You can add button in center of circularSlider.

assuming you want to set the color var as input value and assuming its the only element with class data

you can simply set it like this (shortened your code)

That is because $('#slider') is undefined at the time of the call. Either wrap your entire script in a document.ready callback or move your

LE: Also, this: slide : function(value) should be this: slide: function(ui, value).

Here is what I do when I add a new pod, in addition to what you did already.

• Open the workspace file, go to the project settings page:

• Scroll down and you'll see this:

• Click on the + button and add all the frameworks you wish.

• Command + B to build the project.

• Now import the modules
