- (void)viewDidLoad {
UIButton *checkbox = [UIButton buttonWithType:UIButtonTypeCustom];
CGRect checkboxRect = CGRectMake(135,150,36,36);
[checkbox setFrame:checkboxRect];
[checkbox setImage:[UIImage imageNamed:@"checkbox_off.png"] forState:UIControlStateNormal];
[checkbox setImage:[UIImage imageNamed:@"checkbox_on.png"] forState:UIControlStateSelected];
[checkbox addTarget:self action:@selector(checkboxClick:) forControlEvents:UIControlEventTouchUpInside];

}
那两个off和on的png图片自己做吧,放到resources目录里。你试试看。
