Iphone Application terminate due to uncaught exception 'NSInvalidArgumentException'

I have an application in which i use this code for save data in local prefences.

-(IBAction)radio_button:(id)sender{
switch ( ((UIButton*)sender).tag ){
        NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    case 0:
    {
        [button0 setBackgroundImage:[UIImage imageNamed:@"checkBox_Checked.png"] forState:UIControlStateNormal];
        button0.selected=TRUE;   
        [defaults setInteger: 0 forKey:@"tag_button0"];
        [defaults synchronize];
        NSLog(@"Data saved");



        break;
    }
    case 1:
    {
        [button1 setBackgroundImage:[UIImage imageNamed:@"checkBox_Checked.png"] forState:UIControlStateNormal];
        button1.selected=TRUE;            
        [defaults setInteger:1 forKey:@"tag_button1"];
        [defaults synchronize];
        NSLog(@"Data saved");


        break;
    }
    case 2:
    {
        [button2 setBackgroundImage:[UIImage imageNamed:@"checkBox_Checked.png"] forState:UIControlStateNormal];

        button2.selected=TRUE;            
        [defaults setInteger:2 forKey:@"tag_button2"];
        [defaults synchronize];
        NSLog(@"Data saved");

        break;
    } 
}

} When i run the application then i get error message which i shown below.

            btn3.selected=TRUE;            
            [defaults setInteger:2 forKey:@"tag_button2"];
            [defaults synchronize];

You are declaring your defaults variable inside of the switch. Move it to outside the switch

NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
switch ( ((UIButton*)sender).tag ){
