Objective-C: String reverting

Hi!


Here's a very simple piece of code  to revert/twist/turn a string:

#import <UIKit/UIKit.h>

@interface StringTurnerViewController : UIViewController{

    

    IBOutlet UIButton* BUTTON;

    IBOutlet UITextField* INSERT_TEXT_FIELD;

    IBOutlet UITextField* RESULT_TEXT_FIELD;

    

}

-(IBAction)revertTheString:(id)sender;

-(int)countStringLenght:(NSString *)string;

@end

#import "StringTurnerViewController.h"

@implementation StringTurnerViewController

-(IBAction)revertTheString:(id)sender{

            

    NSString* STRING_TO_TRANSFORM = INSERT_TEXT_FIELD.text;

    NSString* STRING_WHO_WILL_RECEIVE_CHAR_BY_CHAR;

    NSMutableString* STRING_TO_DISPLAY = [NSMutableString string];

    NSMutableString* MUTABLE_STRING_TO_TRANSFORM = [NSMutableString stringWithString:STRING_TO_TRANSFORM];

    int STRING_SIZE;

    

    STRING_SIZE = [self countStringLenght:STRING_TO_TRANSFORM];

    int x;

    for (x=0; x<=[STRING_TO_TRANSFORM length]; x++){

        STRING_SIZE--;

        if(x <= [STRING_TO_TRANSFORM length]-1){

            STRING_WHO_WILL_RECEIVE_CHAR_BY_CHAR = [MUTABLE_STRING_TO_TRANSFORM substringWithRange:NSMakeRange(STRING_SIZE, 1)];

            [STRING_TO_DISPLAY appendString:STRING_WHO_WILL_RECEIVE_CHAR_BY_CHAR];

        }

    }

    

    RESULT_TEXT_FIELD.text = STRING_TO_DISPLAY;

    

}

-(int)countStringLenght:(NSString *)string{

    

    int stringLength = 0;    

    for(int i=0; i<=[string length]; i++){

        stringLength = i;

    }

    return  stringLength;

}

...

@end

Have a good day, pals.
