如何获取数组中的嵌套json数据并显示在表视图中？
问题描述：
我JSON这样 {
“状态”： “成功”， “代码”： “200”， “menudetails”：{
“menu_id”： “1001”， “菜单名称”：”多彩塔利”， “价格”： “$ 200.00”， “面包”：{
“最大”： “1”， “10”： “Akki rotti”， “11”： “SEL烤肉” } ， “rice”：{
“max”：“1”， “14”：“Jeera rice”， “15”：“Biryani”， “16”：“Fried饭” }， “Vegitable”：{
“最大”： “2”， “20”： “梅莱科夫塔”， “21”： “夏希芝士”， “22”： “PALAK芝士” ， “23”： “芝士做piaza” } }， “消息”： “Tranasction列表”， “说明”： “Tranasction列表” } 我尝试调用此API如何获取数组中的嵌套json数据并显示在表视图中？
- （void）callApi {
[SVProgressHUD showWithStatus:nil maskType:SVProgressHUDMaskTypeGradient];
NSMutableDictionary *finaljson = [NSMutableDictionary dictionary];
NSMutableDictionary *postParams = [NSMutableDictionary dictionary];
[postParams setObject:[NSNumber numberWithInt:kresto_id] forKey:@"resto_id"];
AppDelegate*apDelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate];
[postParams setObject:apDelegate.subCategoryID forKey:@"menu_id"];
NSMutableArray * arrjson = [NSMutableArray array];
[arrjson addObject:postParams];
[finaljson setObject:arrjson forKey:@"Data"];
//NSLog(@"Each time Signup postParam is = %@",finaljson);
NSError *error = nil;
NSData *postData = [NSJSONSerialization dataWithJSONObject:finaljson
options:kNilOptions
error:&error];
NSURL *url_request = [NSURL URLWithString:[NSString stringWithFormat:@"%@%@",kBaseURL,kThaliDetail]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url_request
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
// HEADER...STARTS HERE .
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:self delegateQueue:nil];
NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData * data, NSURLResponse * response, NSError * error) {
if (error == nil) { // success....
NSError *jsonError;
id response = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&jsonError];
// get object after successful retrieving data !!!!
dispatch_async(dispatch_get_main_queue(), ^{
[SVProgressHUD dismiss];
NSLog(@"output for Bussiness owner Login:%@",response);
NSString* strStatus = [NSString stringWithFormat:@"%@",[response valueForKey:@"status"]];
if ([strStatus isEqualToString:@"Success"])
{
array = [ response valueForKey:@"menudetails"];
// Ingrediant = [ response valueForKey:@"menulist"];
int currentCount = (int)array.count;
NSLog(@"Scroll view coun = %d", currentCount);
//tblView.separatorStyle = UITableViewCellSeparatorStyleSingleLine;
[tblView reloadData];
}
else
{
}
});
}else {
// fail....
[SVProgressHUD dismiss];
NSLog(@"Error: %@",error);
dispatch_async(dispatch_get_main_queue(), ^{
//No network connectivity - This App requires an internet connection. Please enable the same to proceed
});
}
}];
[postDataTask resume];
}
和表视图代码
- （UITableViewCell的*）的tableView：（UITableView的*）的tableView的cellForRowAtIndexPath：（NSIndexPath *）indexPath {
RestoCommonViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"cellSubCategory"];
[cell.lblSubcategoryName sizeToFit];
[cell.IngdntDiscription sizeToFit];
cell.lblSubcategoryName.text = [NSString stringWithFormat:@"%@",[[arayResponce objectAtIndex:indexPath.row] valueForKey:@"Vegitable"]];
cell.lblSubcategoryName.frame=CGRectMake(cell.lblSubcategoryName.frame.origin.x, cell.lblSubcategoryName.frame.origin.y, cell.lblSubcategoryName.frame.size.width,cell.lblSubcategoryName.frame.size.height);
cell.IngdntDiscription.text = [NSString stringWithFormat:@"%@",[[arayResponce objectAtIndex:indexPath.row] valueForKey:@"description"]];
cell.IngdntDiscription.frame=CGRectMake(20, 20, 20, 20);
cell.IngdntDiscription.frame=CGRectMake(cell.IngdntDiscription.frame.origin.x, cell.lblSubcategoryName.frame.origin.y+cell.lblSubcategoryName.frame.size.height, cell.IngdntDiscription.frame.size.width,cell.IngdntDiscription.frame.size.height);
cell.lblSubCategoryPrice.text = [NSString stringWithFormat:@"%@",[[arayResponce objectAtIndex:indexPath.row] valueForKey:@"price"]];
cell.btnIngredients.tag = indexPath.row;
return cell;
答
我不知道你的基地根据你的输出响应
我创建了示例project.I形式相同的输出，你从response.I得到相同的响应在我的dictionary.From我做以下的事情。

之前您在使用密钥得到的响应值输出，请邮寄或粘贴Online JSON Viewer text and view your response
您回应我检查你的回应在网上json查看器和我得到树结构化的数据。
首先我复制并粘贴回复文本
然后我查看回复。
如果您在项目中使用上述代码，会得到什么结果？ – user3182143
