UIButton Label Resets When Clicked Inside A TableViewCell - ios

Question

I have a custom tableview cell, when I click the "quantity button" inside the cell, the value of the cell itself resets to the value defined the prototype cell on storyboard (which is "1"). So imagine I click the button under the image of the first cell, the label of the button changes from "5" to "1". I commented out all the code when button is pressed, so assume nothing ishapening there. Why is this?
My Custom Cell (.h)
#interface BLCartItemCell : UITableViewCell
#property (weak, nonatomic) IBOutlet UIImageView *imgView;
#property (weak, nonatomic) IBOutlet UILabel *title;
#property (weak, nonatomic) IBOutlet UIButton *quantityBtn;
#property (weak, nonatomic) IBOutlet UIButton *removeBtn;
#property (weak, nonatomic) IBOutlet UILabel *price;
#end
My Custom Cell (.m)
#implementation BLCartItemCell
#end
In my view controller:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
// Section 0: Cart cells
static NSString *cartCellIdentifier = #"cartCell";
BLCartItemCell *cell = [tableView dequeueReusableCellWithIdentifier:cartCellIdentifier];
if (cell == nil) {
cell = [[BLCartItemCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cartCell"];
// [cell.removeBtn addTarget:self action:#selector(removeBtnPressed:) forControlEvents:UIControlEventTouchUpInside];
// [cell.quantityBtn addTarget:self action:#selector(quantityBtnPressed:) forControlEvents:UIControlEventTouchUpInside];
}
// Grab the cart item from cart and set the cell properties
BLCartItem *cartItem = [self.cart.items objectAtIndex:indexPath.row];
cell.title.text = cartItem.title;
cell.quantityBtn.titleLabel.text = [NSString stringWithFormat:#"%i", cartItem.quantity];
cell.price.text = [NSString stringWithFormat:#"$ %.2f", [cartItem totalPrice]];
NSData *image_data = [[NSData alloc] initWithContentsOfURL:cartItem.image];
cell.imgView.image = [UIImage imageWithData:image_data];
// Buttons will keep track of cell index
cell.quantityBtn.tag = indexPath.row;
cell.removeBtn.tag = indexPath.row;
return cell;
I removed the IBActions associated with the button, problem still happens.

I think it has problem when you set buttonTitle like that
cell.quantityBtn.titleLabel.text = [NSString stringWithFormat:#"%i", cartItem.quantity];
try :
[cell.quantityBtn setTitle: [NSString stringWithFormat:#"%i", cartItem.quantity] forState: UIControlStateNormal]];
