Adding checkbox to IOS 6 AlertView

Question

I want to add checkbox view to my UIAlertView. I have made the view in which the button will be placed on :

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 250, 50)];
[buttonCheck setImage:[UIImage imageNamed:@"btn_check_off_holo_light.png"] forState:UIControlStateNormal];

[buttonCheck addTarget:self action:@selector(agreementCheck) forControlEvents:UIControlEventTouchUpInside];

[view addSubview:buttonCheck];

Then I call the UIAlertview

UIAlertView *alertSeat = [[UIAlertView alloc] initWithTitle:[language stringForKey:@"WARNING_SEAT_TITLE"] message:[NSString stringWithFormat:@"%@\n%@\n\n%@", [language stringForKey:@"WARNING_SEAT_SELECTION"], [language  stringForKey:@"WARNING_SEAT_SELECTION2"], [language stringForKey:@"WARNING_SEAT_CONTENT_MESSAGE"]] delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];

[alertSeat setValue:view forKey:@"accessoryView"];
[alertSeat show];

This works well on IOS above 7.0 and above, but gives me following error on IOS 6.1 and below :

*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key accessoryView.'

Have tried searching in Google, but can't find solution. Any help would be appreciated. Thanks

The iOS version before 6 is not the same with the 7. you can see this page custom alter view

the best solution is use the lib named custom alter
