Google Developer Day / Objective-C: String Handling

Hi!

Here's the code i used for the Google Developer Day 2011, i wasn't able to come up with the 4th task, but it came to me a few hours later at home, so as soon as i code it, i'll update the post.

No way i can paint special words.
Sorry.

CODE:


#import <Foundation/Foundation.h>

@interface MyClass : UIViewController {
    
    IBOutlet UIButton* hitItButton;
    IBOutlet UITextField* TEXT;
    
    int VEZES_QUE_ENTROU;
    int VEZES_QUE_SAIU_SEM_SUCESSO;
    
    NSMutableString* POSITION_1;
    NSMutableString* POSITION_2;
    NSMutableString* POSITION_3;
    NSMutableString* POSITION_4;
    NSMutableString* POSITION_5;
    NSMutableString* POSITION_6;
    NSMutableString* POSITION_7;
    NSMutableString* POSITION_8;
    NSMutableString* POSITION_9;
    NSMutableString* POSITION_10;
    NSMutableString* POSITION_11;
    NSMutableString* POSITION_12;
    NSMutableString* POSITION_13;

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.
