KarenPrefs

KarenPrefs is a library that provides various conveniences and enhancements for developers seeking to create preference bundles for their iOS tweaks.

I originally wrote KarenPrefs back in 2013 for use with my tweak mikoto, but only thought about open-sourcing it recently, since I've found it rather useful (especially for when I need to show/hide specifiers according to iOS version, something I use often in mikoto).

The various components of KarenPrefs

IMPORTANT NOTE — PLEASE READ

For features that list the warning "Requires KarenPrefs version [VERSION_HERE] or higher", please make sure to include Depends: net.angelxwind.karenprefs (>= VERSION_HERE) in your control file, or else a subset of your users on outdated KarenPrefs versions will experience preference pane crashes due to missing symbols!

KarenPrefsListController

Tested to work on iOS 14, 13, 12, 11, 10, 9, 8, 7, 6, and 5.

This is a PSListController subclass that basically carries the weight of KarenPrefs' functionality.

In it, I implemented full support for PreferenceLoader's CoreFoundationVersion filters, which is very useful for hiding/showing features according to iOS version.

That aside, I also added a few additional methods.

Here is a description of its basic methods:

1. -(NSString *) karenPrefsLoadFromPlist — Override this method and return the filename (without .plist extension) of your desired plist that you want to load specifiers from. Defaults to nil if not set. This is the only thing you really need to override if you only desire basic functionality (with use of PreferenceLoader filters, etc.) from KarenPrefs.

2. -(BOOL) shouldBypassCfprefsd — If this is overriden to return 1, KarenPrefs will read and write directly from your plist file, bypassing cfprefsd. Use this if you're loading your tweak's preferences directly from your plist on iOS 8+. If you use cfprefsd in your tweak, set this value to 0. Defaults to 1 if not set.

3. -(NSString *) karenPrefsNavbarIconLoadFromImage — Override this method and return the filename (without .png extension) of your desired PNG image that you want to display in the navigation bar. Defaults to nil if not set.

4. -(void) respring — When called, resprings the device intelligently (kills backboardd if running on iOS 6 and above, kills SpringBoard if running on iOS 5 and below).

Here is a description of its extra "convenience" methods (I use these for the "Credits" views in my tweaks' preferences):

1. -(NSString *) karenPrefsDonateURL — Override this method and return an URL that you want to open using -(void) openDonate.

2. -(void) openDonate — When called, opens the URL defined in -(NSString *) karenPrefsDonateURL in the web browser. Does nothing if -(NSString *) karenPrefsDonateURL is nil.

3. -(NSString *) karenPrefsSiteURL — Override this method and return an URL that you want to open using -(void) openSite.

4. -(void) openSite — When called, opens the URL defined in -(NSString *) karenPrefsSiteURL in the web browser. Does nothing if -(NSString *) karenPrefsSiteURL is nil.

5. -(NSString *) karenPrefsRepoURL — Override this method and return an Cydia/APT repo URL that you want to open using -(void) openRepo.

6. -(void) openRepo — When called, opens the Cydia/APT repo URL defined in -(NSString *) karenPrefsRepoURL in the Cydia. If Cydia is not installed (...for whatever reason), then it will display the repo URL in an UIAlertView. Does nothing if -(NSString *) karenPrefsRepoURL is nil.

7. -(NSString *) karenPrefsTwitterUsername — Override this method and return a Twitter username (without the @ username prefix) that you want to open using -(void) openTwitter.

8. -(void) openTwitter — When called, opens the Twitter username defined in -(NSString *) karenPrefsTwitterUsername in the official Twitter app. If the Twitter app is not installed, then it will open Twitter's web UI in the system's default browser instead. Does nothing if -(NSString *) karenPrefsTwitterUsername is nil.

9. -(NSString *) karenPrefsDeviantArtUsername — Requires KarenPrefs version 1.3 or higher. Override this method and return a deviantArt username that you want to open using -(void) openDeviantArt.

10. -(void) openDeviantArt — Requires KarenPrefs version 1.3 or higher. When called, opens the deviantArt username defined in -(NSString *) karenPrefsDeviantArtUsername in the official deviantArt app. If the deviantArt app is not installed, then it will open deviantArt's web UI in the system's default browser instead. Does nothing if -(NSString *) karenPrefsDeviantArtUsername is nil.

11. -(NSString *) karenPrefsGitHubUsername — Requires KarenPrefs version 1.3 or higher. Override this method and return a GitHub username that you want to open using -(void) openGitHub.

12. -(void) openGitHub — Requires KarenPrefs version 1.3 or higher. When called, opens the GitHub username defined in -(NSString *) karenPrefsGitHubUsername in the system's default browser. Does nothing if -(NSString *) karenPrefsGitHubUsername is nil.

13. -(NSString *) karenPrefsPixivID — Requires KarenPrefs version 1.3 or higher. Override this method and return a Pixiv ID that you want to open using -(void) openPixiv.

14. -(void) openPixiv — When called, opens the Pixiv ID defined in -(NSString *) karenPrefsPixivID in the system's default browser. Does nothing if -(NSString *) karenPrefsPixivID is nil.

15. -(NSString *) karenPrefsTumblrUsername — Requires KarenPrefs version 1.3 or higher. Override this method and return a Tumblr username that you want to open using -(void) openTumblr.

16. -(void) openTumblr — Requires KarenPrefs version 1.3 or higher. When called, opens the Tumblr username defined in -(NSString *) karenPrefsTumblrUsername in the official Tumblr app. If the Tumblr app is not installed, then it will open Tumblr's web UI in the system's default browser instead. Does nothing if -(NSString *) karenPrefsTumblrUsername is nil.

17. -(UIColor *) karenPrefsCustomTintColor — Requires KarenPrefs version 1.2 or higher. Override this method and return an UIColor to change the tint color of your preference pane. Defaults to nil if not set.

KarenPrefsBannerCell

Tested to work on iOS 14, 13, 12, 11, 10, 9, 8, 7, 6, and 5.

This is a PSTableCell subclass that sets an image as its own background.

Override -(NSString *) karenPrefsBannerLoadFromImage in your subclass's implementation to specify the filename of the PNG image (without the extension!) in your preference bundle that will be used as a banner.

In order to support the entire range of displays, you must have the following variations present in your bundle:

• Non-Retina Display (iPhone 3GS, etc.): exampleBanner.png

• Retina Display (iPhone 4, 5, etc.): [email protected]

• 4.7-inch Retina HD (iPhone 6, etc.): [email protected]

• 5.5-inch Retina HD (iPhone 6 Plus, etc.): [email protected]

• Super Retina HD Display (iPhone X): [email protected]

The height can be modified via your specifier plist by adding the height key/value pair in your property list. (Example: <key>height</key><integer>205</integer>)

This is a KarenPrefsCustomTextColorButtonCell subclass that changes the text color to black.

Useful if you want a PSButtonCell on iOS 7 and above with black text instead of the default blue.

---

KarenPrefsRedTextButtonCell

Tested to work on iOS 14, 13, 12, 11, 10, 9, 8, 7, 6, and 5.

KarenPrefsBounceBackSwitchCell

Tested to work on iOS 14, 13, 12, 11, 10, 9, 8, 7, and 6. Requires KarenPrefs version 1.2 or higher.

Note that while this does not work on iOS 5, if the preference pane you are using this in also supports iOS 5, you must add -F$(SYSROOT)/System/Library/PrivateFrameworks -weak_framework Preferences to your TweakName_LDFLAGS Makefile variable to avoid a crash.

This is a PSSwitchTableCell subclass that is in a perpetual "on" state. When tapped, the switch will animate itself "bouncing back" to the on state.

In order for this to function properly, you must override -(NSString *) karenPrefsBounceBackObserverName with the name of an NSNotificationCenter observer. The way this works is that when the observer is called, the switch will be set to the "on" state.

Useful for communicating to users that there are options that cannot be disabled and are always enabled.
