EXC_BAD_ACCESS when swizzling AVAudioSession setCategory:withOptions:error:

[josipbernat]

Hi,

I'm trying to swizzle AVAudioSession's - (BOOL)setCategory:(NSString )category withOptions: (AVAudioSessionCategoryOptions)options error:(NSError *)outError method. Problem is that each time someone try to set category I get EXC_BAD_ACCESS. I assume problem is with this NSError ** but I'm unclear how to modify implementation then. Do you have some suggestion?

This is what I try to do:

[AVAudioSession swizzleInstanceMethod:@selector(setCategory:withOptions:error:)
                      withReplacement:JGMethodReplacementProviderBlock {

                          //return a replacement block
                          return JGMethodReplacement(BOOL, AVAudioSession *, NSString *category, AVAudioSessionCategoryOptions options, NSError **error) {

                              // We want to use AVAudioSessionCategoryPlayback always.
                              BOOL orig = JGOriginalImplementation(BOOL, AVAudioSessionCategoryPlayback, options, error);

                              //return the modified value
                              return orig;
                          };
}];

Yes, NSError ** is probably the culprit, where exactly is the exception thrown?

It's just EXC_BAD_ACCESS unfortunately.
