Unable to reload the UItableview - ios

Question

I had some data in my UITableView with four labels (Project,tasks, subtasks and hours), I changed my data from the backend (going to database and changed the data). I changed number of hours from 12 to 10. But I was only seeing the old data (12 hours instead of 10 hours) in my UITableView. Can any one suggest what is the reason behind that. I tried to clean, restart the computer which doesn't load the correct data that is in database. Other thing I can add is I was retrieving the data with the help of web service. and converting the data from JSONSerialization format to NSArray. When I ping my web service in browser URL, it gives me the correct data. Here is the below code :
- (void)viewDidLoad
{
[super viewDidLoad];
[self loadprojects];
}
NSString *strwebsite = [[NSUserDefaults standardUserDefaults] valueForKey:#"website"];
NSString *websitemethods = #"Timesheet.svc/GetTimesheet";
NSString *projecturltemp = [strwebsite stringByAppendingString:websitemethods];
NSString *str = [[NSUserDefaults standardUserDefaults] valueForKey:#"UserLoginIdSession"];
NSString *usrid = str;
NSString * projecturl =[NSString stringWithFormat:#"%#/%#/%#",projecturltemp,usrid,eventDate];
NSURL *url = [NSURL URLWithString:projecturl];
[self.tableView reloadData];
NSLog(#"url : %#", url);
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:#"%lu", (unsigned long)[postData length]];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:url];
[request setHTTPMethod:#"POST"];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"application/projectpicker" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/jsonArray" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody:postData];
NSError *error = [[NSError alloc] init];
NSHTTPURLResponse *response = nil;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
//NSLog(#"urlData : %#",urlData);
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReturnCacheDataElseLoad
timeoutInterval:30];
// Make synchronous request
urlData = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse:&response
error:&error];
if ([response statusCode] >= 200 && [response statusCode] < 300)
{
NSString *responseDatatest = [NSJSONSerialization JSONObjectWithData:urlData
options:NSJSONReadingAllowFragments error:&error];
NSLog(#"responseDatatest : %#",responseDatatest);
NSArray *entries = [NSJSONSerialization JSONObjectWithData:[responseDatatest dataUsingEncoding:NSUTF8StringEncoding]
options:0 error:&error];
NSLog(#"Entries : %#", entries);
if(!entries)
{
NSLog(#"Error : %#", error);
}
else{
for (NSDictionary *entry in entries) {
projectNames = [entries valueForKey:#"NM_PROJECT"];
taskNames = [entries valueForKey:#"TASk_NAME"];
subtaskNames = [entries valueForKey:#"SUBTASK_NAME"];
timesheetid = [entries valueForKey:#"ID_TIMESHEET_DTLS"];
projId = [entries valueForKey:#"ID_PROJECT"];
taskId = [entries valueForKey:#"ID_TASK"];
subtaskId = [entries valueForKey:#"ID_SUB_TASK"];
totalhours = [entries valueForKey:#"No_Hours"];
approve = [entries valueForKey:#"FL_APPROVE"];
leaves = [entries valueForKey:#"NM_LEAVE"];
}
}
} else {
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
// Return the number of sections.
return 1;
}
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [projectNames count];
}
-(UITableViewCell*) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identitifier = #"Cell";
TableViewCell * cell = [tableView
dequeueReusableCellWithIdentifier:identitifier
forIndexPath:indexPath];
if ([[[timesheetid objectAtIndex:indexPath.row] stringValue] isEqualToString:#"0"])
{
cell.lblProjects.text = [NSString stringWithFormat:#"%#",#"No Projects Filled"];
cell.lblTasks.text = [NSString stringWithFormat:#"%#",#"No Tasks Filled"];
cell.lblSubTasks.text = [NSString stringWithFormat:#"%#",#"No SubTasks Filled"];
cell.lblHours.text = [NSString stringWithFormat:#"%#",#"0 Hours Filled"];
cell.accessoryType = UITableViewCellAccessoryNone;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
else if ([[leaves objectAtIndex:indexPath.row] isEqualToString:#"0"])
{

cell.lblTasks.text = [taskNames objectAtIndex:indexPath.row];
cell.lblSubTasks.text = [subtaskNames objectAtIndex:indexPath.row];
cell.lblHours.text = [[totalhours objectAtIndex:indexPath.row] stringValue];
//NSLog(#"cell :%#",cell.lblHours.text);
}
else
{
cell.lblProjects.text = [leaves objectAtIndex:indexPath.row];
cell.lblTasks.text = [NSString stringWithFormat:#"%#",#"No Projects/Tasks on this Date"];
cell.lblSubTasks.text = [NSString stringWithFormat:#"%#",#"No Sub Tasks on this Date"];
cell.lblHours.text = [[totalhours objectAtIndex:indexPath.row] stringValue];
}
cell.editingAccessoryType = UITableViewCellAccessoryDetailDisclosureButton;
NSNumber *myProjectArrayString = [timesheetid objectAtIndex:indexPath.row];
cell.hdbrowcount = [NSString stringWithFormat:#"%#",myProjectArrayString];
return cell;
}

Answer 1

I don't see this line
[self.tableview reloadData];

Answer 2

use postnotification whenever change data.
[[NSNotificationCenter defaultCenter] postNotificationName:#"refresh" object:self];
