I have seen a few iphone apps with color wheels but i am not sure how they were created for if the source code is available.
I was wondering if anyone has seen a color wheel in an ipad app or ideas on how to go about creating one. If that is not possible purchasing source code is an option for me.

Hi I am building a hybrid mobile app and wish to use this color for an alert. However, I cannot seem to get the color right along with the opacity. Does anyone know how to achieve this extremely subtle blur/transparency of this volume alert background? Thanks!
Is there a way to change the display from an iOS app to filter out the blue light?
There is a f.lux app, but it is only available through cydia, so I figured iOS might not give regular apps the power to do this?
If you mean globally, then no. That's the reason F.lux is only available through Cydia as you mentioned.
If you mean only for your own app then you could simply tint all graphical elements in a more yellow tint though some clever tricks.
I want to have a glossy button in my iPhone app (in the style of the black toolbar). However, as you all know, those are not included in the SDK.
So I wonder if anyone knows where to get ready to use button images.
I have of course googled for that, but I could not find any useful graphics. My requirements to button graphics are:
should match Apple's style used in the black toolbar / titlebar
should have resolution high enough for retina devices
should be available for commercial use (does not need to be free)
I have also taken a look at some programmatic solutions like Michael Heyeck's Shiny Red Buttons which are quite well done. However I would prefer to have a simple png file to use as a button background image.
You can try the link here - it might help .
I'm currently working on an UI to crop an image inside my app, and I'd like it to feel as native as possible. I looked to the iPad's built in Photos app for some ideas, and noticed that when you crop an image, instead of a blue "Done" button, it has a yellow tinted button that has "Crop" on it, like so:
Does anyone know how to replicate this? I recall that the UIKit framework had a bunch of artwork stored inside of it in some custom file format and an iOS app existed that was able to read this and save you the individual PNGs, but I do not remember what this app is called. Conveniently enough for me, the thing I remember is that this yellow button graphic was among those contained. Anyone got any ideas how I can replicate the button nevertheless?
(Although if anyone knows that utility, that'd be great.)

How can I implement a color picker for my app like this: http://cl.ly/8pqv
into my application?
And possibly compatible with iOS 3.0?
Or are there any librarie? I need the wheel with all colors..
I actually have a class called ANColorPicker. It provides a wheel interface with a brightness selector on the side. You can check it out on the ANColorPicker Github Repository. There are also a few forks of this project that have different features/capabilities in which you may be interested.
You might try this method. Basically, you would create your own image of a color wheel, then when the user touches part of the image, you find the color of the pixel at the touch point and make that the currently selected color. Otherwise, if you don't have to have a circular color picker, here is an example of a square color picker with source code.
I thought I would throw my color picker into the ring. I use it in my app, You Doodle and I spent a couple weeks making it and testing it in the app. It contains a sample project to show you how to get started with it and is open sourced under the MIT license. It supports any device (iOS 6+), any resolution and portrait and landscape. Favorites, recents, color by hue, color wheel and importing textures, as well as deleting and moving favorites to the front is supported.
I've tried to combine the good pieces of all the other color pickers and ensure that the MIT license allows a no hassle integration into any project.
