Presence of UITextField and Pixate Freestyle Crashes on iOS 9

Question

All of my view controllers that contain UITextField objects crash with the following on iOS 9 in the Simulator:

-[UITextField preventStyling]: unrecognized selector sent to instance 0x7fa8b96d6330

Failed to set (styleClass) user defined inspected property on (UITextField): -[UITextField preventStyling]: unrecognized selector sent to instance 0x7fa8b96d6330

Anyone else running into this with Pixate Freestyle? Any ideas? I logged an issue on the GitHub repo, but it doesn't appear anyone is monitoring those: https://github.com/Pixate/pixate-freestyle-ios/issues/186

Answer 1

This is a Copy & paste of my solution: https://github.com/Pixate/pixate-freestyle-ios/issues/192

Hi folks,

Like other people, i had several problems with PixateFreestyle framework when i upgraded to Xcode to 7 and Mac OS X El capitan.

After some days researching, i decided to compile my own version of PixateFreestyle framework in order to avoid this problems.

You have my version here: https://www.dropbox.com/s/9cz035h67y9x7fd/PixateFreestyle.framework.zip?dl=0

If you add this framework to your project, when you execute Simulator or create an archive with bitcode enabled all will works like a charm.

If you want to build your own PixateFreestyle framework from source code, follow this steps:

• Download the project from github
• Fix the callSuper1v issue: #186
• Build a universal framework with a custom script
• Add bitcode support in build process [optional]
• Add resulting framework to your project

Regards.

I have also run into this problem and my solution, far from perfect, is working :D From this post, I have been able to fix three problems: The preventStyling, playsNicelyWithGestures and _isInteractiveTextSelectionDisabled selector errors. Moreover, I had to add one more function: requiresKeyEvents. With this, problem solved :D

Thank you :)

While Pixate is no longer supported, a new framework named StylingKit is. StylingKit uses all of Pixate's code in the background so all of your methods should still work and it will not run into any iOS 9 issues.

The exception to this rule is any Pixate static methods like [PixateFreestyle updateStylesForAllViews]. In this case, you can create accessor methods in the StylingKit.m and StylingKit.h files to use the hidden PixateFreestyle functions.

For example if your project relies on updating CSS themes through [PixateFreestyle updateStylesForAllViews], you can create a new method declaration in StylingKit.h like:

    @interface StylingKit : NSObject

        -(void)PixateUpdateStylesForAllViews;
        -(void)OtherHiddenPixateMethod;

Then implement those methods in the StylingKit.m file.

    @implementation StylingKit

        -(void)PixateUpdate
        {
            [PixateFreestyle updateStylesForAllViews];
        }

        -(void)OtherHiddenPixateMethod
        {
            //Your PixateFreeStyle code here
        }

Finally you can call these methods from your project with

    [[StylingKit sharedKit] PixateUpdate];
    [[StylingKit sharedKit] OtherHiddenPixateMethod];
