iOS need help to insert a button to UIView.

Iam working on GMGridView and do some customization. Given :
1. I have a gridView containing gridViewCell
2. I have button called checkBox
My Goal is to add checkBox for every gridViewCell
Below what I have so far

- (GMGridViewCell *)GMGridView: (GMGridView *)gridView cellForItemAtIndex: (NSInteger)index
{  
    CGSize size = [self sizeForItemsInGMGridView:gridView];
    
    GMGridViewCell *cell = [gridView dequeueReusableCell];
    
    if (!cell) 
    {
        cell = [[GMGridViewCell alloc] init];
        // create an UIView
        UIView      *view       =   [[UIView alloc] initWithFrame:CGRectMake(0, 0, size.width, size.height)];
 
        // do some customization for my view
        view.backgroundColor = [UIColor purpleColor];
        view.layer.masksToBounds = NO;
        view.layer.cornerRadius = 8;
        view.layer.shadowColor = [UIColor grayColor].CGColor;
        view.layer.shadowOffset = CGSizeMake(5, 5);
        view.layer.shadowPath = [UIBezierPath bezierPathWithRect:view.bounds].CGPath;
        view.layer.shadowRadius = 8;

        // create a button called checkBox
        UIButton    *checkBox   =   [[UIButton alloc] initWithFrame:CGRectMake(70, 20, 150, 25)];
        [checkBox   setTitleColor:[UIColor purpleColor] forState:UIControlStateNormal];
        [checkBox   setImage:[UIImage imageNamed:@"checkbox_not_ticked"] forState: (UIControlStateNormal)];
            // add checkbox to my view
[B]        [view addSubView: checkBox]  [/B]
        cell.contentView = view;

    }

after running it, no checkbox is shown on each cell. I cant see the bug.. Please help if you were experiencing before
I did attach an picture so you can take a look about it
( Again : my goal is to display checkbox on each purple cell)

[B]        [view addSubView: checkBox]  [/B]

Well, it looks like you've already highlighted the line that is the problem. Objective-C is case sensitive. You should make sure you don't ignore compiler errors, which that line should be giving you one.

Thanks for pointing it out. I have just made a change to

[view addSubview:checkBox];

It did not work either.. Until I figured it out the problem lies on the line below

[[cell.contentView subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];

The line was already there after I added a checkBox to my view
Can you explain because I did not add any subview to my superview which is my cell....

Was already there? What does that mean? Are you saying Xcode is adding lines of code to your project without your permission?
