Toggle the button Image

After i implemented a code for give an check image for a button but i want to give check image for no of buttons.

note: if i click on one button check image can be displayed and the same time i click on another button check image displayed on that particular button and previous button comes normal position.

i implement the code for single button here like this.

-(void) setChecked:(BOOL) check 


{


_checked = check;


if( _checked )


{
    UIImage* img = [UIImage imageNamed:@"btn_check_on.png"];

[self setImage:img forState:UIControlStateNormal];

   }
    else

{

    UIImage* img = [UIImage imageNamed:@"bread_Wheat_rectangle.png"];


    [self setImage:img forState:UIControlStateNormal];


}


}

The above code is executed successfully but how to use this code for no of buttons.

After long practicing this problem we can use switch cases it can be done very easily

switch (currenttagvalue) {
    case 1:
        [level1 setImage:[UIImage imageNamed:@"one_time_selected.png"] forState:UIControlStateNormal];  
        [level2 setImage:[UIImage imageNamed:@"ic_launcher.png"] forState:UIControlStateNormal];
        [level3 setImage:[UIImage imageNamed:@"bread_sourdough_rectangle.png"] forState:UIControlStateNormal];

        }

in this level is "IBOutlet UIButton level1;"

And then i implement so more buttons

This is how I have implemented it for one button. You can use it for more buttons too.

-(IBAction)ButtonAction
{

    if (Flag==0) 
    {
        Flag=1;
        [myButton setImage:[UIImage imageNamed:@"checkbox-filled.png"] forState:UIControlStateNormal];  

    }
    else
    {
        [myButton setImage:[UIImage imageNamed:@"checkbox.png"] forState:UIControlStateNormal];
       Flag=0;

    }
}

Note : If you want only one button to get checked Just set all other buttons image as checkbox.png and the selected one's checkbox-filled.png.

EDIT

You can make a class for checkbox and then use it. Here is the code...

CheckButton.h

#import <Foundation/Foundation.h>


@interface CheckButton : UIButton {
    BOOL        _checked;
    int chkButtonClickVal;
}

@property (nonatomic, setter=setChecked:) BOOL checked;

-(void) setChecked:(BOOL) check;
-(int)chkButtonClickVal;
@end

CheckButton.m 

#import "CheckButton.h"


@implementation CheckButton
@synthesize checked = _checked;

-(id) init
{
    if( self=[super init] )
    {
        chkButtonClickVal=0;
        self.checked = NO;
        [self addTarget:self action:@selector(OnCheck:) forControlEvents:UIControlEventTouchUpInside];
    }
    return self;
}

-(void) awakeFromNib
{
    self.checked = NO;
    [self addTarget:self action:@selector(OnCheck:) forControlEvents:UIControlEventTouchUpInside];
}

-(void) dealloc
{
    chkButtonClickVal=0;
    [super dealloc];
}

-(void) setChecked:(BOOL) check 
{
    _checked = check;
    if( _checked )
    {
        UIImage* img = [UIImage imageNamed:@"checkbox-checked.png"];
        [self setImage:img forState:UIControlStateNormal];
        chkButtonClickVal=1;

    }
    else
    {
        UIImage* img = [UIImage imageNamed:@"checkbox.png"];
        [self setImage:img forState:UIControlStateNormal];
        chkButtonClickVal=2;
    }
    //NSLog(@"%d",chkButtonClickVal);
}

-(int)chkButtonClickVal
{
    return chkButtonClickVal;   
}

-(void) OnCheck:(id) sender
{
    self.checked = !_checked;
}

@end

I have done it in same way. Try you'll be able to achieve it. Good Luck :)
