Objective c 如果没有崩溃消息，我的表视图将崩溃

这是我的代码，请验证它，朋友：

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    NSInteger count=[[arrParsingProduct valueForKey:@"description"] count];
    return count;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSInteger count=[[arrParsingProduct valueForKey:@"description"]count];

    return count;

}

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


    productSub=[tableView dequeueReusableCellWithIdentifier:@"cell1"];

    NSLog(@"entering");
    productSub.lblSubProduct.text=[NSString stringWithFormat:@"%@",[[arrParsingProduct objectAtIndex:indexPath.row] valueForKey:@"description"]];


    return productSub;

}

-(UIView*)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    NSString *str=[NSString stringWithFormat:LocalImage@"%@",[[arrParsingProduct objectAtIndex:section] valueForKey:@"image"]];
    self.imgHeader.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:str]]];
    self.lblHeaderproduct.text=[NSString stringWithFormat:@"%@",[[arrParsingProduct objectAtIndex:section] valueForKey:@"name"]];
    self.lblHeaderCost.text=[NSString stringWithFormat:@"%@",[[arrParsingProduct objectAtIndex:section]valueForKey:@"price"]];
    [self.btnHeader addTarget:self action:@selector(touchup:) forControlEvents:UIControlEventTouchUpInside];
    return self.view;
}

没有崩溃消息。我试图用断点来找出问题所在。我感到困惑。请任何人告诉我可能是什么问题？

在viewforheaderin部分，您正在返回self.view；这不是创建UIView对象并返回该对象的正确方法

UIStoryboard *objStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    ViewController *objVC = [objStoryboard instantiateViewControllerWithIdentifier:@"headerView_identifier"];
return objVC.view;

数组[arrParsingProduct]中的“description”包含哪个值？它包含字符串值@meghsdhameliya我看不到productSub的类型（UItableViewCell*productSub），另一个问题是dequeueReusableCellWithIdentifier，您应该使用DequeueReusableCellWithIdentifier来扩展字典值的数组组是否存在…@meghsdhameliya这是表视图单元格类@MohamadFarhand
