我使用此代码比较两个NSNumber对象,但它从未传递if条件.

listItems = [appDelegate.productStatus componentsSeparatedByString:@","];


for (int i=0;i<[appDelegate.productArray count]; i++)
{

    for (int j=0; j<[listItems count]; j++) 
    {
        number=[NSNumber numberWithInt:[[listItems objectAtIndex:j] intValue]];
        NSLog(@"number %@",number);
        productObject=[appDelegate.productArray objectAtIndex:i];           
        NSLog(@"%@,%@",productObject.pid,number);
        if (productObject.pid == number) 
        {
            NSLog(@"BUY it!!!");
            [purchasArray addObject:productObject];
        }

    }
}

怎么了？

在我的应用程序中,我有一个imageView和一个UILabel.对于ImageView,我已经为它分配了asynch Image并且它工作正常,但是当我滚动表时,第一行和最后一行的标签重叠.

这是我的代码:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    productObject=[appDelegate.productArray objectAtIndex:indexPath.row];
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    UILabel *nameLabel;
    if (cell == nil) 
    {

        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero     reuseIdentifier:CellIdentifier] autorelease];
        cell.selectionStyle = UITableViewCellSelectionStyleBlue;

    }   

    else 
    {

        AsyncImageView* oldImage = (AsyncImageView*)[cell.contentView viewWithTag:999];
        [oldImage removeFromSuperview];
    }

    CGRect nameLabelRect = CGRectMake(70,80,150,15);
    nameLabel = [[UILabel alloc] initWithFrame:nameLabelRect];    
    nameLabel.text = [NSString stringWithFormat:@"%@",productObject.productname];
    nameLabel.textAlignment = UITextAlignmentCenter;
    nameLabel.lineBreakMode = UILineBreakModeCharacterWrap;
    nameLabel.font = [UIFont boldSystemFontOfSize:15];
    nameLabel.backgroundColor = [UIColor clearColor];
    [cell.contentView addSubview: nameLabel]; …
