how to reload table view when I'm in a class? - ios

Question

I have a table view on InquiryViewController that I want to be reloaded when I click the update status button. The update status button is a JSON that gets the status of a message.
Here's the code:
-(BOOL)getMessageStatus : (NSMutableArray *)emails : (UIAlertView *)alert : (UIProgressView *)progress : (InquiryLogViewController *)controller
{
_emailsInApi = [[NSArray alloc]init];
_emailsInApi = [[DBManager getSharedInstance]arrayOfEmails];
NSMutableArray *newArrayEmail = [[NSMutableArray alloc]init];
NSString *arrayEmail =#"";
for(int i = 0; i<[_emailsInApi count]; i++){
arrayEmail = [_emailsInApi objectAtIndex:i];
[newArrayEmail addObject:arrayEmail];
}
NSURL *url = [NSURL URLWithString:#"http://www.url.com/API/2.0/message.php"];
NSDictionary *params =#{#"api_key":#"APIKEYIOS",#"action":#"get-message-status",#"email":newArrayEmail};
NSLog(#"params: %#",params);
NSData *paramsData = [NSJSONSerialization dataWithJSONObject:params
options:NSJSONWritingPrettyPrinted
error:nil];
NSString *paramsString = [[NSString alloc]initWithData:paramsData encoding:NSUTF8StringEncoding];
paramsString = [paramsString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
paramsString = [paramsString stringByReplacingOccurrencesOfString:#"%5C" withString:#""];
NSString *post = [NSString stringWithFormat:#"params=%#", paramsString];
NSData *sendData = [post dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:sendData];
NSURLSessionDataTask *task = [[NSURLSession sharedSession] dataTaskWithRequest:request
completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
{
if (!error)
{
NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"response...... = %#", responseString );
//get data frm response
self.responseData = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
self.responseArray = [self.responseData objectForKey:#"data"];
for(NSDictionary *items in self.responseArray)
{
Inquiry *inq = [[Inquiry alloc]init];
inq.email = [items objectForKey:#"to_email"];
inq.status = [items objectForKey:#"status_id"];
[emails addObject:inq];
}
float newProg = (float)1 - (float)[emails count] / (float)5;
dispatch_async(dispatch_get_main_queue(), ^{
[progress setProgress:newProg animated:YES];
});
dispatch_async(dispatch_get_main_queue(), ^{
[[DBManager getSharedInstance]updateInquirylog:emails];
});
dispatch_async(dispatch_get_main_queue(), ^{
controller.arrayOfEmails = [[DBManager getSharedInstance]loadInquiries];
[controller.tableViews reloadData];
});
dispatch_async(dispatch_get_main_queue(), ^{
[alert dismissWithClickedButtonIndex:0 animated:YES];
});
}
else
{
self.alert = [[UIAlertView alloc] initWithTitle:nil message:error.localizedDescription delegate:self cancelButtonTitle:#"OK" otherButtonTitles: nil];
self.responseData = nil;
[alert show];
}
}];
[task resume];
return YES;
}
My problem here is in: [controller.tableViews reloadData];
It doesn't reload my table. Why? Help me please. Thank you
EDIT: This json is in a class
Ok I'm sorry. I forgot to include my table view method.
Here it is:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellID =#"Cell";
tableCellOfInquiryLog *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (tableView == self.searchDisplayController.searchResultsTableView){
if(cell == nil)
{
NSArray *topLevelObjects = [[NSBundle mainBundle]loadNibNamed:#"searchCell" owner:self options:nil];
cell = [topLevelObjects objectAtIndex:0];
}
Inquiry *inquiry = [searchResult objectAtIndex:indexPath.row];
cell.sInquiry_id.text =[NSString stringWithFormat:#"%d",inquiry.ID];
cell.sName.text = inquiry.name;
cell.sItem.text = inquiry.item_name;
cell.sDate.text = inquiry.dDate;
cell.status.layer.cornerRadius = 10;
if ([inquiry.status isEqual: #"1"]) {
cell.status.backgroundColor = [UIColor greenColor];
}
else if ([inquiry.status isEqual: #"2"]) {
cell.status.backgroundColor = [UIColor orangeColor];
}
else if ([inquiry.status isEqual: #"3"]) {
cell.status.backgroundColor = [UIColor redColor];
}
return cell;
}
else
{
if(cell == nil)
{
cell = [[tableCellOfInquiryLog alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
Inquiry *inquiry = [arrayOfInquiries objectAtIndex:indexPath.row];
cell.inquiry_id.text =[NSString stringWithFormat:#"%d",inquiry.ID];
cell.name.text = inquiry.name;
cell.item.text = inquiry.item_name;
cell.date.text = inquiry.dDate;
cell.status.layer.cornerRadius = 10;
if ([inquiry.status isEqual: #"1"]) {
cell.status.backgroundColor = [UIColor greenColor];
}
else if ([inquiry.status isEqual: #"2"]) {
cell.status.backgroundColor = [UIColor orangeColor];
}
else if ([inquiry.status isEqual: #"3"]) {
cell.status.backgroundColor = [UIColor redColor];
}
return cell;
}
return nil;
}

Answer 1

create a instance of your tableview and the add the given code in which ever method u want to add to [self.nameoftableview reloaddata]

Answer 2

if (indexPath.section ==1) {
cell = [tableView dequeueReusableCellWithIdentifier:section1identifier];
cell = nil;//here i have made it nil
if (!cell)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:section1identifier];
data *newObj = [callingObj.itemslist objectAtIndex:indexPath.row];
UITextView *titlelabel = [[UITextView alloc]initWithFrame:CGRectMake(cell.frame.origin.x+5, cell.frame.origin.y-2, 320, 38)];
titlelabel.textColor = [UIColor redColor];
titlelabel.font= [UIFont fontWithName:#"Times New Roman" size:FONT_SIZE];
titlelabel.text = newObj.title;
titlelabel.scrollEnabled = NO;
titlelabel.editable = NO;
[cell.contentView addSubview:titlelabel];
desView = [[UITextView alloc]initWithFrame:CGRectMake(cell.frame.origin.x,cell.frame.origin.y+25 , 320, i + 160)];
desView.text = newObj.description;
desView.editable = NO;
desView.hidden = NO;
[cell.contentView addSubview:desView];
if (check == NO) {
desView.hidden = YES;
}
}
}
return cell;
