iOS, alertView for specific element in custom cell - ios

Question

i have a custom cell for a table, is working fine,
Im showing a list of products in the cells, when the user touches a button "delete", i show an alert view to confirm deletion,
but I need to show the name of the product in the alert view: "are you sure you want to delete XXX?"
here the code for my custom cell
Please note the call to the alert view in deleteCartButtonPressed
#import "ShoppingCartProductsCell.h"
#import "Product.h"
#implementation ShoppingCartProductsCell
#synthesize categoryNameLabel = _categoryNameLabel;
#synthesize productNameLabel = _productNameLabel;
#synthesize quantityPicker = _quantityPicker;
#synthesize deleteCartButton = _deleteCartButton;
#synthesize product = _product;
- (void) dealloc {
[_deleteCartButton release];
[_categoryNameLabel release];
[_productNameLabel release];
[_quantityPicker release];
[super dealloc];
}
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
//self = [super initWithFrame:frame];
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
[self initQuantityPicker];
[self initLabels]; //y picker!
[self initButtons];
}
return self;
}
- (void) initQuantityPicker {
CGRect contentRect = self.contentView.bounds;
CGFloat boundsX = contentRect.origin.x;
self.quantityPicker = [[[BDFDropDownList alloc] initWithFrame:CGRectMake(boundsX+220, 8, 61, 28) popupWidth:90]autorelease];
self.quantityPicker.delegate = self;
for (int i = 1; i<=20; i++) {
[self.quantityPicker addOptionWithName:[NSString stringWithFormat:#"%d",i] value:[NSNumber numberWithInt:i]];
}
[self.contentView addSubview:self.quantityPicker];
}
- (void) initLabels {
self.productNameLabel = [[[UILabel alloc]init] autorelease];
self.productNameLabel.textAlignment = UITextAlignmentLeft;
self.productNameLabel.backgroundColor = [UIColor clearColor];
self.productNameLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:15];
self.productNameLabel.textColor = [UIColor colorWithRed:102/255.0f green:102/255.0f blue:102/255.0f alpha:1];
[self.contentView addSubview:self.productNameLabel];
}
- (void) initButtons {
self.deleteCartButton = [UIButton buttonWithType:UIButtonTypeCustom];
[self.deleteCartButton addTarget:self action:#selector(deleteCartButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[self.deleteCartButton setImage:[UIImage imageNamed:#"deleteCartButton.png"] forState:UIControlStateNormal];
[self.contentView addSubview:self.deleteCartButton]; //Calculations For stage 2
}
- (void)layoutSubviews {
[super layoutSubviews];
CGRect contentRect = self.contentView.bounds;
CGFloat boundsX = contentRect.origin.x;
CGRect frame;
frame= CGRectMake(boundsX+10 ,10, 200, 20);
self.productNameLabel.frame = frame;
frame= CGRectMake(boundsX+330 ,8, 30, 29); //310
self.deleteCartButton.frame = frame;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
// Configure the view for the selected state
}
- (void) setProduct:(Product*)product {
[self setProduct:product withQuantity:0];
}
- (void) setProduct:(Product*)product withQuantity:(NSInteger)quantity {
[_product release];
_product = product;
[_product retain];
self.productNameLabel.text = product.SKU;
self.quantityPicker.delegate = nil;
[self.quantityPicker setSelectedIndex:quantity-1]; //testa
self.quantityPicker.delegate = self;
}
- (void) deleteCartButtonPressed:(id) sender {
NSLog(#"Delete ");
UIAlertView *deleteAlert = [[UIAlertView alloc]initWithTitle:#"Attention" message:#"Are you sure you want to delete this record?" delegate:nil cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
[deleteAlert show];
[deleteAlert release];
}
#end
Thanks a lot!

string literals are your friend.
- (void) deleteCartButtonPressed:(id) sender {
NSLog(#"Delete ");
UIAlertView *deleteAlert = [[UIAlertView alloc]initWithTitle:#"Attention" message:[NSString stringWithFormat:#"Are you sure you want to delete %#?", [myTableDatasource objectAtIndex:idx]], delegate:nil cancelButtonTitle:#"Cancel" otherButtonTitles:#"Ok", nil];
[deleteAlert show];
[deleteAlert release];
}
It's probably best to move this out of your cell subclass and into your datasource and delegate so as to facilitate cleaner code.
