在我的表格视图单元格中，我需要在单个单元格中显示我的数组元素的内容，如果我插入任何新内容，则不会覆盖以前的内容。以前的内容和我的新内容应该按顺序显示。这里是我的代码
- (void)viewDidLoad
{
[super viewDidLoad];
NSMutableArray *arrMain=[NSMutableArray arrayWithObjects: cnfqty, cnftitle, cnfrate, nil];
finarray=[[NSMutableArray alloc]init];
[finarray addObjectsFromArray:arrMain];
NSLog(@"%@",finarray);
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 150.0;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return ( [finarray count] / 3 );
}
- (UITableViewCell *) getCellContentView:(NSString *)cellIdentifier {
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
UILabel *tempLabel;
//UIImage *tempImage;
/* Create UI elements - Customize as you want your text to appear */
CGRect myFirstLabel = CGRectMake (65, 10, 200, 15);
CGRect mySecondLabel = CGRectMake (65, 25, 200, 15);
CGRect myThirdLabel = CGRectMake (65, 40, 200, 15);
// CGRect myImage = CGRectMake (10, 10, 50, 50);
//Initialize first label
tempLabel = [[UILabel alloc] initWithFrame: myFirstLabel];
tempLabel.tag = 1;
tempLabel.font = [UIFont boldSystemFontOfSize:12];
tempLabel.textColor = [UIColor lightGrayColor];
[cell.contentView addSubview: tempLabel];
//Initialize second label
tempLabel = [[UILabel alloc] initWithFrame: mySecondLabel];
tempLabel.tag = 2;
tempLabel.font = [UIFont boldSystemFontOfSize:12];
tempLabel.textColor = [UIColor lightGrayColor];
[cell.contentView addSubview: tempLabel];
//Initialize third label
tempLabel = [[UILabel alloc] initWithFrame: myThirdLabel];
tempLabel.tag = 3;
tempLabel.font = [UIFont boldSystemFontOfSize:12];
tempLabel.textColor = [UIColor lightGrayColor];
[cell.contentView addSubview: tempLabel];
//Initialize your picture
//imgTemp = [[UIImageView alloc] initWithFrame: myImage];
//imgTemp.tag = 4;
//[cell.contentView addSubview: tempImage];
return cell;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"aCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [self getCellContentView: CellIdentifier];
}
//This will create the actual UI elements
UILabel *tempLabel1 = (UILabel *)[cell viewWithTag: 1];
UILabel *tempLabel2 = (UILabel *)[cell viewWithTag: 2];
UILabel *tempLabel3 = (UILabel *)[cell viewWithTag: 3];
//UIImageView *tempImage = (UIImageView *)[cell viewWithTag: 4];
// Populate the labels
NSString *firstText = [NSString stringWithString: [finarray objectAtIndex: 3*(indexPath.row)]];
NSString *secondText = [NSString stringWithString: [finarray objectAtIndex: 3*(indexPath.row) + 1]];
NSString *thirdText = [NSString stringWithString: [finarray objectAtIndex: 3*(indexPath.row) + 2]];
// Populate the picture
//UIImage *picture = [[UIImage alloc] initWithData:theObjectToPutInCell.picture];
tempLabel1.text = firstText;
tempLabel2.text = secondText;
tempLabel3.text = thirdText;
// tempImage.image = picture;
return cell;
}
}

我的代码面临的问题是每个字符串都显示在每个单元格中，如果我插入任何新字符串，以前的内容就会消失，只显示新内容。
为了清楚地了解这个问题，我正在尝试为在线购物实现“添加到购物车”服务。根据概念，必须从各种产品中添加项目，它会保存产品信息，并且必须在表格视图中显示详细信息.但我不明白..
请指导..提前谢谢..
我的输出就像第一张图片
但我需要将显示为在 Android 中完成的第二张图像..
