UITableViewCell 存储在其他数组中

【中文标题】UITableViewCell 存储在其他数组中

【问题描述】：

我有一个数组（arrData）和 UITableViewCell 重新加载 arrData。 arrData 存储在 Web 服务对象数组中。 UITableViewCell 中一个二标签一图片，标签和图片通过arrData 加载数据。所以所有标签和图像都重新加载在同一个数组中，但我想为每个标签和图像重新加载不同的数组。

视图控制器

#import "ViewController.h"
#import "MemberTableViewCell.h"
#import "member_details.h"

@interface ViewController ()
 
NSArray *arrData;
 

@end

@implementation ViewController

 - (void)viewDidLoad 
[super viewDidLoad];

[self.tabel_view setAllowsMultipleSelection:YES];

NSURLRequest *req=[[NSURLRequest alloc]initWithURL:[NSURL URLWithString:@"http://edutimeapp.com/toshow/chamber-of-commerc/ws/fetch_member.php"]];
response =[[NSMutableData alloc]init];
[NSURLConnection connectionWithRequest:req delegate:self];

 

 -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
 
[response appendData:data];
NSLog(@"error receving data %@",response);


   -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
   

  
 -(void)connectionDidFinishLoading:(NSURLConnection *)connection
    

     NSError *error;

    NSLog(@"Error in receiving data %@",error);
    NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves  error:&error];
  NSLog(@"response data %@",json);
  
   NSArray *status = json[@"status"];
   arrData = status;
   [self.tabel_view reloadData];
    


- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
  
  NSArray<NSIndexPath *> *selectedRows = [tableView indexPathsForSelectedRows];
if (selectedRows && [selectedRows containsObject:indexPath]) 
    
    return 127.0; // Expanded height


return 50.0; // Normal height
 


 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
 
return 1;
 
 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 
return [arrData count];
 



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


MemberTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ht"];
if (cell==nil)

    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"Cell" owner:self options:nil];
    cell = [nib objectAtIndex:0];




cell.name.text= [[arrData objectAtIndex:indexPath.row] valueForKey:@"business_category_name"];
cell.title.text= [[[[arrData objectAtIndex:indexPath.row] valueForKey:@"business_details"] objectAtIndex:0] valueForKey:@"name"];
cell.email.text=[[[[arrData objectAtIndex:indexPath.row] valueForKey:@"business_details"] objectAtIndex:0] valueForKey:@"email"];

cell.image_view.image  = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[[[[arrData objectAtIndex:indexPath.row]valueForKey:@"business_details"]objectAtIndex:0] valueForKey:@"img_url"]]]];

return  cell;

 

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

[self updateTableView];


- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath

[self updateTableView];


- (void)updateTableView

[self.tabel_view beginUpdates];
[self.tabel_view endUpdates];
 
@end

【问题讨论】：

你的问题不清楚，提供arrData中包含的数据。同时让我们知道您是在使用 xib 的原型单元还是自定义单元？

@BharatModi 带有情节提要的自定义单元格，我将编辑我的问题。

@BharatModi 我将更新我的问题，请再次检查。谢谢

那你为什么要从笔尖加载单元格呢？如果您使用的是原型单元格，那么您的 cellForRowAtIndexPath 应该如下所示， cellIdentifier = @"cellReviews";单元格 = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];您是否记录了 arrData，提供相同的内容。

【参考方案1】：

试试这个代码

#import "ViewController.h"
@interface ViewController ()

IBOutlet UITableView *tbl;
NSMutableData *response;
NSMutableArray *Arrdata;
NSMutableArray *ArrySubData;

@end
@implementation ViewController
- (void)viewDidLoad

Arrdata=[[NSMutableArray alloc]init];
ArrySubData=[[NSMutableArray alloc]init];
[tbl setAllowsMultipleSelection:YES];
NSURLRequest *req=[[NSURLRequest alloc]initWithURL:[NSURL URLWithString:@"http://edutimeapp.com/toshow/chamber-of-commerc/ws/fetch_member.php"]];
response =[[NSMutableData alloc]init];
[NSURLConnection connectionWithRequest:req delegate:self];

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data

[response appendData:data];
NSLog(@"error receving data %@",response);
 
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
 
 
-(void)connectionDidFinishLoading:(NSURLConnection *)connection

NSError *error;

NSLog(@"Error in receiving data %@",error);
NSMutableDictionary *json = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves  error:&error];
NSLog(@"response data %@",json);
    NSArray *status = json[@"status"];
Arrdata = status;
NSLog(@"%@",Arrdata);
[tbl reloadData];
 
 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 
 ArrySubData=[[Arrdata objectAtIndex:section] objectForKey:@"business_details"];
return ArrySubData.count;

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section 

return [NSString stringWithFormat:@"  %@",[[Arrdata objectAtIndex:section] objectForKey:@"business_category_name"]];

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section

return 25;

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section 


UILabel *myLabel = [[UILabel alloc] init];

myLabel.text = [self tableView:tableView titleForHeaderInSection:section];
UIView *headerView = [[UIView alloc] init];
[headerView addSubview:myLabel];
return headerView;
 
 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 
 static NSString *CellIdentifier = @"Cell";
 UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
 if (cell == nil)
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

UILabel *lblPhone = (UILabel *) [cell viewWithTag:104];

ArrySubData=[[Arrdata objectAtIndex:indexPath.section] objectForKey:@"business_details"];
NSString *strName=[NSString stringWithFormat:@"%@",[[ArrySubData objectAtIndex:indexPath.row] objectForKey:@"name"]];
NSString *stremail=[NSString stringWithFormat:@"%@",[[ArrySubData objectAtIndex:indexPath.row] objectForKey:@"email"]];
NSString *strphone=[NSString stringWithFormat:@"%@",[[ArrySubData objectAtIndex:indexPath.row] objectForKey:@"phone"]];
NSString *strimage=[NSString stringWithFormat:@"%@",[[ArrySubData objectAtIndex:indexPath.row] objectForKey:@"image"]];

lblName.text=strName;
lblEmail.text=stremail;
lblPhone.text=strphone;
ImgBrands.image  = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:strimage]]];
return  cell;


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

[self updateTableView];

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath

[self updateTableView];

- (void)updateTableView

[tbl beginUpdates];
[tbl endUpdates];

【讨论】：

您可以在部分显示business_category_name，在单元格中显示地址、手机、电子邮件和图片
