Fix some compiler warnings



A Cocoa-Touch system for getting a color scheme in function of an image, like iTunes 11 does. It is designed as a general purpose class set, in wich LEColorPicker is the interface for your client code.

LEColorPicker_Vortex LEColorPicker_Mona

Release note: Current release (1.0) run faster in devices than simulator.


  • Add the OpenGLES framework to your project.
  • Drag the 'LEColorPickerDemo/LEColorPicker' folder into your project, and you are done.


First, you have to create an instance of a LEColorPicker object. Then, LEColorPicker class provides an instance method that receives an UIImage as input and returns a LEColorScheme object. LEColorScheme will provide the three computed colors as properties.

#import "LEColorPicker.h"
LEColorPicker *colorPicker = [[LEColorPicker alloc] init];
LEColorScheme *colorScheme = [colorPicker colorSchemeFromImage:image];
aView.backgroundColor = [colorScheme backgroundColor];
titleTextField.textColor = [colorScheme primaryTextColor];
bodyTextField.textColor = [colorScheme secondaryTextColor];

About the sample images

All images are public domain. If you want to add your own testing images, drag the image to the Resources folder of the project, in Xcode. Don't use names with "Default" or will be filtered. Only PNG images are supported (for now) in the sample project.
