How to use the category

How to use the category, could you please give me an example?

[ipinka]

Just like this

#import "NSNumber+AvoidMTLModelCrash.h"
int main(int argc, char * argv[])
{
    @autoreleasepool {
       [NSNumber avoidMTLModelCrash];
       return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

Thanks for your suggestion!

It's ugly to do that in main. Why not just add it to the category's +(void)load.
