Presented simple and nice solution for radio buttons, based on the UIButton.

Add buttons on view of controller

5
6
7
8
9

for (int i = 0; i < 5; i++) {
UIButton *but = [UIButton buttonWithType:UIButtonTypeCustom];
[but setImage:[UIImage imageNamed:@"checkbox.png"] forState:UIControlStateNormal];
[but setImage:[UIImage imageNamed:@"checkedbox.png"] forState:UIControlStateSelected];
[but setFrame:CGRectMake(0, 0, 17, 17)];
[but setCenter:CGPointMake( 50, i*40+20 )];
[but addTarget:self action:@selector(checkboxButton:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:but];
}

Action for buttons:

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

if ([but isKindOfClass:[UIButton class]] && ![but isEqual:button]) {
[but setSelected:NO];
}
}
if (!button.selected) {
button.selected = !button.selected;
}
}

you can will get UI from here
