Hello i'm iOS fresher & don't have so much idea about creating complex UI, i want to create equalizer UI like spotify's equalizer UI. currently i had setup my equalizer using UISlider. What should i use to modify my UI like spotify'S EQ UI. It will be nice if you can help with Example code.
Thank you.
This is my EQ UI.
This is what i want to create. EQ UI of spotify.
The approach could be simple:
Make the color of your sliders gauges clear so they are transparent
Read the values of your sliders and draw lines between them
Create a polygon with the coordinates of your sliders values + the two points at the bottom and fill it with a color gradient
As your sliders are equally spaced you can deduce their x position knowing the width of the graph container, the y value is the slider current value + some correction with the slider button size.

Is it possible to configure a angular material slider like that one in the picture?
There's only a invert option. But this doesn't suit for me.
I am currently using XCode 8 and Swift 3 and I have been searching and haven't been able to find a way of being able to complete what I want to do - basically, I want to be able to have a progression box behind text which I am able to drag from the left to the right to be able to have a 0-100 slider. I have created a mock-up to be able to attempt to describe what I am attempting to achieve, the progression bars in the background should be able to be slideable which will update the progression number once it has let go.
Any help would be appreciated on this as I have been stumped for awhile now.
Here is the mock-up:
One method: use a UISlider "under" the labels. Might be able to get away with tint colors - if not, then transparent images for thumb and max track image, and just-a-little translucent image for min track image.
Hi I'm making a baseball app and I want from users to input strike zone on a grid like this:
How can I build the visual part so that I won't have too much trouble with implementation of a tap gesture recogniser. It'll be great if I can make this resizable so it will look great on many different devices.
With the touch gesture I need to handle so kind of recognizing position in two ways.
In which section the touch was detected.
What are the approximate coordinates inside this section.
This data will be saved on a cloud and can be later used to show the dot on this grid on other devices.
Is there a way to detect touch in a non rectangular shapes? Maybe with Bezier Paths.
Do you have a suggestion how ti appear on screen without using whole grid as a image. I'd rather divide it in Outer grid and the Inner grid somehow and than create all the pieces in each of this grids. 8 pieces in outer and 9 in inner grid.
You can start with UIBezierPath and its method containsPoint:, although this method "does not take into account the line width used to stroke the path." (link), it is also true for UIBezierPath.
Refer further to this article.
I would like UIButtons to arc around a center point.
The image below shows the end result I would like, where all of the grey elements are buttons. Optimally, I would like math that supports an arbitrary amount of buttons arced around the same center, and distribute space evenly.
Can this be done with standard elements? Do I need to create a single custom shape and use as a button? Or will I need a custom shape for each of the buttons below?
You can use CAShapeLayers, each having a path that's constructed out of concentric arcs, with a fillColor. You can achieve the gap by incrementing the angle by a delta amount for each sector.
Edit: Alternatively you can create just one path, and apply a rotation transform on copies of it around the center.
Checkout this Github - https://github.com/Planet1107/CustomShapedButtons/. I think it demonstrates exactly what you need.
I want to draw graph in iOS native app (Making app using auto layout and Xcode 6.1)..after googling I found core plot lib for drawing graph.
I am struggling with this library to do make pie,bar,donut and line chart as I want.
I used the examples which are in 'examples' folder of this library.
How do I make graph to adjust when app is rotating and takes auto
layout constraints?
For bar/line chart-I don't get idea to make graph compact or make
scroll when there is large data to show on x or y axis?
For any chart- How do I show legends(title or explanation for
graph)?
How do I show values on bar/pie/line itself(Value on each
pie slice / every bar/ every line point)?
Can I set X and Y axis start and end point?
Please help if anybody have an idea? Thanks in advance.
The Plot Gallery example app demonstrates all of these things. You'll need to use the latest code from GitHub (release 1.5.1 doesn't have some of the newer features like auto layout; 1.6 will be out soon, but isn't quite ready yet).
The iOS version of the Plot Gallery uses a storyboard and auto layout to control the UI.
Set allowsUserInteraction to YES on the plot space to enable pinch zoom and scrolling behavior. You can disable pinch gestures and keep the scrolling behavior with the allowPinchScaling property on the hosting view.
Many of the Plot Gallery demos have legends. Look for CPTLegend in the code. Ask a more specific question if you need more help with this.
These are known as "data labels" in Core Plot. Many of the Plot Gallery demos have them. You can set a formatter and text style on the plot to turn them on, or use a plot delegate to have more control over each label.
Set the xRange and/or yRange of the plot space associated with the axes to control the coordinate space of the plot area.
