int main(int argc, const char * argv[]) {
    @autoreleasepool {
        int i = 10;
        switch (i) {
            case 1:
                NSLog(@"i=1");
                break;
            case 2:
                NSLog(@"i=2");
                break;
            default:
                NSLog(@"i!=1 && i!=2");
                break;
        }
    }
