(If you too like to live dangerously) this will get rid of the following error message when running on the iOS Simulator: `Cannot find executable for CFBundle <CertUIFramework.axbundle>`

STFU_UIAccessibilityLoader.m

// When the `accessibility inspector' is enabled on the iOS Simulator the private `UIAccessibility'
// framework is loaded. In turn it will try to load a list of bundles amongst which is one that has
// only resources, no executable. This leads to `CFBundleLoadExecutableAndReturnError' logging this
// offending error message.
//
// This code omits the `SDK_ROOT/System/Library/AccessibilityBundles/CertUIFramework.axbundle'
// bundle from ever being attempted to load.

I included this file in my project,but i got a error: can't find this file.I still puzzled about how to use and make this file.

@RoyWangChina , I met the same problem, but has been resolved, is to directly add STFU_UIAccessibilityLoader.m files to the project can be

hi~ i met this problem in xcode6.3, my app run in ios8 is perfect, but in ios7 it would crash!! can u help me? thanks~
