return [self->isa stringFromAsciiBytes: [NSData dataFromBase64String: self]];

/NSString+Kolyvan.m:349:19: Direct access to Objective-C's isa is deprecated in favor of object_getClass()

Can you send my e-mail this full source or upload at dropbox? I need this app. But I can't build this app because this source has an error.

#if __OBJC2__
    return [[self class] stringFromAsciiBytes: [NSData dataFromBase64String: self]];
#else
    return [self->isa stringFromAsciiBytes: [NSData dataFromBase64String: self]];
