@synthesize passwordCheck;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    self.navigationController.navigationBarHidden=YES;

    //忘记密码按钮
    BECheckBox *passCheckBox=[[BECheckBox alloc]initWithFrame:CGRectMake(61, 55, 80, 30)];
    [passCheckBox setTitle:@"记住密码" forState:UIControlStateNormal];
    [passCheckBox setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];

    passCheckBox.backgroundColor=[UIColor clearColor];
    self.passwordCheck=passCheckBox;
    [self.view addSubview:self.passwordCheck];

    if ([self.passwordCheck isChecked]) {
        NSLog(@"记住密码");
    }
    else {
        NSLog(@"取消记住密码");
