Color Picker Library For iOS

libcolorpicker

The new libcolorpicker:

The new libcolorpicker PFColorAlert is focused on being lightweight, portable, and easy to use.

How to implement:

• Search and install the latest libcolorpicker from Cydia.

• Copy /usr/lib/libcolorpicker.dylib from your iOS device to your $THEOS/lib folder.

• Add TWEAKNAME_LIBRARIES = colorpicker to your Tweak's Makefile if needed

• Add TWEAKNAMEPREFS_LIBRARIES = colorpicker to your Pref's Makefile if needed

• Download libcolorpicker.h from the root of this git and place in $THEOS/include folder.

Adding libcolorpicker into your tweak prefs bundle (Simple)

This simple method is for devs that don't need much customization.

add a new dictionary in your preference's specifier plist like this (also see example below)

** Preferences Plist Specifier Format **

		<dict>
			<key>cell</key>
			<string>PSLinkCell</string>
			<key>cellClass</key>
			<string>PFSimpleLiteColorCell</string>
			<key>libcolorpicker</key>
			<dict>
				<key>defaults</key>
				<string>YOUR PREFS PLIST IDENTIFIER</string>
				<key>key</key>
				<string>SAVE KEY</string>
				<key>fallback</key>
				<string>FALLBACK HEX COLOR</string>
				<key>PostNotification</key>
				<string>NOTIFICATION TO POST (OPTIONAL)</string>
				<key>alpha</key>
				<true/> <!-- <true/> or <false/> Show alpha slider -->
			</dict>
			<key>label</key>
			<string>COLOR TEXT LABEL</string>
		</dict>

** Example Preferences Plist**

		<dict>
			<key>cell</key>
			<string>PSLinkCell</string>
			<key>cellClass</key>
			<string>PFSimpleLiteColorCell</string>
			<key>libcolorpicker</key>
			<dict>
				<key>defaults</key>
				<string>com.baileyseymour.someawesometweak</string>
				<key>key</key>
				<string>favoriteColor</string>
				<key>fallback</key>
				<string>#ff0000</string>
				<key>alpha</key>
				<false/>
			</dict>
			<key>label</key>
			<string>Favorite Color 1</string>
		</dict>

Advanced

Showing the alert (Advanced):

this way can be used inside any application like a UIAlertView and is fully customizable.

NSString *readFromKey = @"someCoolKey"; //  (You want to load from prefs probably)
NSString *fallbackHex = @"#ff0000";  // (You want to load from prefs probably)

UIColor *startColor = LCPParseColorString(readFromKey, fallbackHex); // this color will be used at startup
PFColorAlert *alert = [PFColorAlert colorAlertWithStartColor:startColor showAlpha:YES];

// show alert and set completion callback
[alert displayWithCompletion:
	^void (UIColor *pickedColor) {
		// save pickedColor or do something with it
		NSString *hexString = [UIColor hexFromColor:pickedColor];
		hexString = [hexString stringByAppendingFormat:@":%f", pickedColor.alpha];
		// you probably want to save hexString to your prefs
		// maybe post a notification here if you need to
	}];

Reading saved color later on (From Tweak):

NSDictionary *prefsDict = ... // assuming this holds your prefs
NSString *coolColorHex = [prefsDict objectForKey:@"someCoolKey"]; // assuming that the key has a value saved like #FFFFFF:0.75423

UIColor *coolColor = LCPParseColorString(coolColorHex, @"#ff0000"); // fallback to red (#ff0000)
// do something with coolColor

The old libcolorpicker:

libcolorpicker is a iOS library that provides an easy to implement Color Picker. Here are some of it's main features:

• iPhone & iPad Compatible
• HSB touch color picker
• Option to Use HSB or RGB sliders
• Option for color transparency/opacity/alpha
• No images or "extra components" just the library
• Post settings changed notifications on save (Optional)
• Enter a hex color or copy one to your clipboard
• Made for iOS 7 & 8, Compatible with iOS 6
• Saves colors instantly to your preferences plist
• iPhone 3.5 inch & 4inch screen compatibility
• Open Source

How to add libcolorpicker into your tweak:

First add a this into your Tweaks Preferences specifier plist and modify to your liking:

		<dict>
			<key>cell</key>
			<string>PSLinkCell</string>
			<key>cellClass</key>
			<string>PFColorCell</string>
			<key>label</key>
			<string>A Color</string>
			<key>color_defaults</key>
			<string>com.yourcompany.tweak</string>
			<key>color_key</key>
			<string>aColor</string>
			<key>title</key>
			<string>A Color</string>
			<key>color_fallback</key>
			<string>#10b6ec</string>
			<key>usesRGB</key>
			<false/>
			<key>usesAlpha</key>
			<true/>
			<key>color_postNotification</key>
			<string>com.yourcompany.tweak.settingschanged</string>
		</dict>

Using Version on BigBoss (Recommended)

• Search and install libcolorpicker from Cydia.

• Copy /usr/lib/libcolorpicker.dylib from your iOS device to your $THEOS/lib folder.

• Add TWEAKNAME_LIBRARIES = colorpicker to your Tweak's Makefile

• Add TWEAKNAMEPREFS_LIBRARIES = colorpicker to your Pref's Makefile

• Next Add the following to to your Preference Bundle's PSListController @implementation

    - (void)viewWillAppear:(BOOL)animated
    {
    	[self clearCache];
    	[self reload];
    	[super viewWillAppear:animated];
    }
  

---

PLEASE DO NOT DO THIS :P It will result in loading different versions of libcolorpicker.

Using Custom Build

Next, Place the libcolorpicker.dylib in TweakPreferencesFolder/lib/

Next, Add the following to your Preference Bundle's Makefile:

$(shell install_name_tool -id /usr/lib/libcolorpicker_PUTTWEAKNAMEHERE.dylib lib/libcolorpicker.dylib)

TWEAKNAMEPREFERENCES_LDFLAGS = -Llib -lcolorpicker

include $(THEOS_MAKE_PATH)/bundle.mk

internal-stage::
$(ECHO_NOTHING)mkdir -p $(THEOS_STAGING_DIR)/Library/PreferenceLoader/Preferences$(ECHO_END)
$(ECHO_NOTHING)mkdir -p $(THEOS_STAGING_DIR)/usr/lib/$(ECHO_END)
$(ECHO_NOTHING)cp lib/libcolorpicker.dylib $(THEOS_STAGING_DIR)/usr/lib/libcolorpicker_PUTTWEAKNAMEHERE.dylib$(ECHO_END)

Next, Add the following to to your Preference Bundle's PSListController @implementation:

- (void)viewWillAppear:(BOOL)animated
{
	[self clearCache];
	[self reload];  
	[super viewWillAppear:animated];
}

Getting the color from the plist:

To get the color from your tweak you can use the UIColor *colorFromDefaultsWithKey(NSString *defaults, NSString *key, NSString *fallback) function found in libcolorpicker.mm

First you need to define the function in your header (.h) file: UIColor *colorFromDefaultsWithKey(NSString *defaults, NSString *key, NSString *fallback);

An example on how to use it would be: UIColor *someColor = colorFromDefaultsWithKey(@"com.example.tweak", @"someColor", @"#ffffff");

This would fallback to white (#ffffff) if the color is nil;
