Tableview with Section ( Data Divided in Sections )
1) Set Your Storyboard Like This :
2) Write This Code in ViewController :
ViewController.h :
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@property(strong,nonatomic)IBOutlet UITableView *tblBudget;
@property (strong,nonatomic) NSMutableArray *arrItem;
@end
ViewController.m :
#import "ViewController.h"
#import "TableViewCell.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize arrItem,tblBudget ;
- (void)viewDidLoad {
[super viewDidLoad];
self.arrItem = [[NSMutableArray alloc]initWithCapacity:0];
[self fetchListOfBudget];
}
# pragma mark - Fetch Data from API -
-(void)fetchListOfBudget
{
NSMutableData *postData = [[NSMutableData alloc] initWithData:[[NSString stringWithFormat:@"tag=%@",@"list_budget"] dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[[NSString stringWithFormat:@"&event_id=100"] dataUsingEncoding:NSUTF8StringEncoding]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://.....Your_URL"]
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:10.0];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:postData];
NSURLSession *session = [NSURLSession sharedSession];
NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^{
});
if (error) {
NSLog(@"%@", error);
}
else
{
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
NSLog(@"%@", httpResponse);
NSError* error;
NSDictionary* responseDict = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&error];
NSLog(@"responseDict: %@", responseDict);
if(!error)
{
if([responseDict[@"error"] intValue] == 0)
{
dispatch_async(dispatch_get_main_queue(), ^{
id object = responseDict[@"data"];
if (![object isKindOfClass:[NSMutableArray class]]) {
[tblBudget reloadData];
return;
}
NSMutableArray *arrAllItem = [[NSMutableArray alloc]initWithArray:responseDict[@"data"]];
if (arrAllItem.count>0)
{
NSMutableArray *arrCategory = [arrAllItem valueForKeyPath:@"category_id"];
NSMutableArray *unique = [NSMutableArray array];
for (id obj in arrCategory) {
if (![unique containsObject:obj]) {
[unique addObject:obj];
}
}
arrCategory = [[NSMutableArray alloc] initWithArray:unique];
for (int i = 0 ; i< arrCategory.count; i++)
{
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(category_id == %@)",arrCategory[i]];
NSArray *filteredArray = [arrAllItem filteredArrayUsingPredicate:predicate];
if (filteredArray.count > 0)
{
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithCapacity:0];
[dict setObject:arrCategory[i] forKey:@"category_id"];
[dict setObject:filteredArray[0][@"category"] forKey:@"category_name"];
[dict setObject:filteredArray forKey:@"item_list"];
[self.arrItem addObject:dict];
NSLog(@"%@",dict);
}
}
[tblBudget reloadData];
}
});
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
// [CommonFunctions showAlertMessage:[responseDict valueForKey:@"error_msg"]];
});
}
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"Error in pass json");
});
}
}
}];
[dataTask resume];
}
#pragma mark - Table view methods -

{
return self.arrItem.count;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
if (cell == nil)
{

}

}
@end
3) Write This Code in UITableViewCell :
UITableViewCell.h :
#import <UIKit/UIKit.h>
@interface TableViewCell : UITableViewCell
@property IBOutlet UILabel *lblItemName;
@property IBOutlet UILabel *lblCost;
@property IBOutlet UILabel *lblPaid;
@end
**** Your API return this type of Data , Here Example is given below
data = (
{
"actual_amount" = 90;
category = Band;
"category_id" = 1;
"created_by" = 3;
"created_date" = "2016-08-11 02:22:28";
"del_flag" = 0;
due = 40;
"estimated_amount" = 190;
"event_id" = 100;
id = 552;
item = Catering;
notes = "Enter Notes";
paid = 50;
prc = 90;
status = 1;
"updated_by" = 3;
"updated_date" = "2016-08-12 06:52:41";
},
{
"actual_amount" = 0;
category = "Event Venue";
"category_id" = 5;
"created_by" = 3;
"created_date" = "2016-08-11 02:22:28";
"del_flag" = 0;
due = 0;
"estimated_amount" = 60;
"event_id" = 100;
id = 556;
item = Venue;
notes = "";
paid = 0;
prc = 60;
status = 1;
"updated_by" = 0;
"updated_date" = "0000-00-00 00:00:00";
},
**** OUTPUT
