getting data in connectionDidFinishLoading,but ubable to use those data in cellForRowAtIndexPath method - iphone

Question

I am developing an iphone application. In this i have to generate user profile form dynamically according to field information coming from the server.
So, if there are 5 fields in response i want ton create 5 labels from those data to display in cell of uitableview.
Not that i am getting the name of fields for user profile, not the values of profile.
I want to generate form dynamically from those data.
I'm able to get those data in NSMutableArray but in cellForRowAtIndexPath method its showing null.
How can i solve this?
My code snippet is as follow.
-(void) connectionDidFinishLoading:(NSURLConnection *)connection {
if (connection)
{
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
//You've got all the data now
//Do something with your response string
// NSLog(#"Response:%#",responseString);
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSDictionary *object = [parser objectWithString:responseString error:nil];
NSString *pec_count = [object valueForKey:#"peculiarity_count"];
NSDictionary *pecs = [object valueForKey:#"peculiarities"];
NSMutableArray *array = [[NSMutableArray alloc] initWithObjects:nil];
[array addObject:#""];
for (int j= 1; j <= [pec_count integerValue] ; j++) {
NSString *val = [NSString stringWithFormat:#"%#%d",#"pec_",j];
NSString *pec_i = [pecs valueForKey:val];
NSString *modifiedString = [pec_i stringByReplacingOccurrencesOfString:#"_" withString:#" "];
NSString *capitalisedSentence = [modifiedString stringByReplacingCharactersInRange:NSMakeRange(0,1)
withString:[[modifiedString substringToIndex:1] capitalizedString]];
[array insertObject:capitalisedSentence atIndex:j];
}
self.peculiarity = array;
[self.table reloadData];
}
for (int j=0 ; j < [self.peculiarity count] ; j++) {
NSLog(#"info:%#", [self.peculiarity objectAtIndex: j]);
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UIButton *racebtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
racebtn.frame = CGRectMake(240, 7, 10, 15);
[racebtn setBackgroundImage:[UIImage imageNamed:#"select.png"] forState:UIControlStateNormal];
[racebtn addTarget:self action:#selector(selectRace:)forControlEvents:UIControlEventTouchUpInside];
NSLog(#"cell=%#",[self.peculiarity objectAtIndex:3]);
}
Any help will be appreciated.
Thank you.

Answer 1

in connectionDidFinishLoading: method replace the following line:
self.peculiarity = array; with,
self.peculiarity = [[NSMutableArray alloc] initWithArray:array];
and in cellForRowAtIndexPath method add the following line of code:
cell.textLabel.text = [self.peculiarity objectAtIndex:indexPath.row];
hope this will help you.

Note: If you did not allocated self.peculiarity NSMutableArray then alloc that array like bellow..
if (self.peculiarity == nil)
self.peculiarity = [[NSMutableArray alloc] init];
and then assign that array to this array like bellow..
self.peculiarity = array;
after in cellForRowAtIndexPath: method just set that value or name to the textLabel Of the UITableViewCell like bellow..
cell.textLabel.text = [self.peculiarity objectAtIndex:indexPath.row];
see whole example with that method..
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
UIButton *racebtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
racebtn.frame = CGRectMake(240, 7, 10, 15);
[racebtn setBackgroundImage:[UIImage imageNamed:#"select.png"] forState:UIControlStateNormal];
[racebtn addTarget:self action:#selector(selectRace:)forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:racebtn];
cell.textLabel.text = [self.peculiarity objectAtIndex:indexPath.row];
}
return cell;
}

I already have checked all above solutions before, Then finally i got solution for this. The problem was that my cell was getting loaded before arrival of data. So i used synchronous request to the server.
Code is below for this :
NSString *path = [[NSBundle mainBundle] objectForInfoDictionaryKey:#"path"];
NSString *address = [NSString stringWithFormat:#"%#%#%#%#", path,#"users/",#"peculiarity/",self.tablename];
NSURL *URL = [NSURL URLWithString:address];
NSLog(#"%#",address);
[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[URL host]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL cachePolicy:NSURLCacheStorageAllowedInMemoryOnly
timeoutInterval:60.0];
[request setHTTPMethod:#"GET"];
NSURLResponse *response = nil;
NSError *error = nil;
NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
if (data) {
NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"data:%#",responseString);
SBJsonParser *parser = [[SBJsonParser alloc] init];
NSDictionary *object = [parser objectWithString:responseString error:nil];
pecs = [object valueForKey:#"pec_values"];
for (int j =0; j < [pecs count] ; j++) {
NSLog(#"values:%#",[pecs objectAtIndex:j]);
}
self.peculiarity = array;
}
else {
// Handle error by looking at response and/or error values
NSLog(#"%#",error);
}
