        /// By simply calling the original method the nil argument is handled. :shrug: :ok:
        ///
        /// (yes, we will call the original method and not ourselves even though it looks like it,
        /// because the methods have been swapped.)

Should I import "NSString+Swizzle.h" into AppDelegate.m and run load() function or it works without import anything.
If should import, please show me how to import it into AppDelegate.m
Please answer me @623637646, I stuck at this for the whole day, Thanks.

Hi @kyunkakata , No need to import it. Just add those files to your project. The + (void)load will be called automatically.

Thank you @623637646

@kyunkakata Thanks your code :)
Can I use your code in my commercial app?
Please let me know how I can use the code for commercial distribution.

That was @623637646 's code.

hi @seyoung-hyun . Feel free to use it. do remember to test before release to live.

@kyunkakata Sorry for confusing you.
@623637646 Thanks your reply :)

hi @kyle-ilantzis.
I wonder if I use your code at this gist in my commercial app, too.
Please let me know how I can use the code for commercial distribution.
Thanks :)
