UIButton *Radiobutton = [UIButton buttonWithType:UIButtonTypeCustom];

 [Radiobutton setImage:[UIImage imageNamed:@"checkbox.png"] forState:UIControlStateNormal];

 [Radiobutton setImage:[UIImage imageNamed:@"checkedbox.png"] forState:UIControlStateSelected];

 [Radiobutton setFrame:CGRectMake(0, 0, 17, 17)];

 [Radiobutton addTarget:self action:@selector(checkboxButton:) forControlEvents:UIControlEventTouchUpInside];
     [self.view addSubview:Radiobutton];

and Action should be alike ----------------------------

- (IBAction)checkboxButton:(UIButton *)button{

     for (UIButton *Radiobutton in [self.view subviews]) {
          if ([Radiobutton isKindOfClass:[UIButton class]] && ![Radiobutton isEqual:button]) {
               [Radiobutton setSelected:NO];
          }
     }
     if (!button.selected) {
          button.selected = !button.selected;
     }
}

Cool!Thanks for this code! But I want that to preserve the selected radiobutton,that when i again open that view ,the radiobutton which i had selected should remain selected.

Thanks in advance!
