iOS : Query regarding dynamically created array - ios

Question

I get four parameters from a web service (web service 2 in my flow) - slno, order, flag, name. I don't know how many times these parameters are going to be received. Out of these four paramters, I send 'name' to a label as it contains questions to be asked.
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"some url"]];
NSLog(#"Web service 2 url is = %#", url);
NSString *json = [NSString stringWithContentsOfURL:url encoding:NSASCIIStringEncoding error:&error];
NSLog(#"Json data = %# \n error = %#", json, error);
if(!error)
{
NSData *jsonData = [json dataUsingEncoding:NSASCIIStringEncoding];
NSArray *myJsonArray = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:Nil];
//NSArray *arrayLabel = [[NSArray alloc] initWithObjects:label1, label2, label3, label4, label5, label6, nil];
//NSMutableArray *tempArray = [NSMutableArray arrayWithCapacity:myJsonArray.count];
i = 0;
for(NSDictionary *myJsonDictionary in myJsonArray)
{
//UILabel *label = (UILabel *)[arrayLabel objectAtIndex:i++];
//[label setText:myJsonDictionary[#"Name"]];
NSString *name = myJsonDictionary[#"Name"];
NSLog(#"Question from ws2 is %#", name);
projectIdGobal = myJsonDictionary[#"ProjectID"];
NSLog(#"Project id from ws2 is %#", projectIdGobal);
slno = myJsonDictionary[#"SLNO"];
NSLog(#"slno from ws2 is %#", slno);
NSString *idWS2 = myJsonDictionary[#"ID"];
NSLog(#"id from ws2 is %#", idWS2);
order = myJsonDictionary[#"Order"];
NSLog(#"order from ws2 is %#", order);
flag = myJsonDictionary[#"Flag"];
NSLog(#"flag from ws2 is %#", flag);
[self putLabelsInScrollView:name];
i++;
}
NSLog(#"Number of cycles in for-each = %d", i);
[activity stopAnimating];
}
- (void) putLabelsInScrollView:(NSString *)labelText
{
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, yPosition_label, 261, 30)];
[label setFont:[UIFont fontWithName:#"Helvetica Neue" size:12.0f]];
label.numberOfLines = 2;
[label setText:labelText];
[self.scroll addSubview:label];
yPosition_label += 90;
UITextField *text = [[UITextField alloc] initWithFrame:CGRectMake(10, yPosition_text, 261, 30)];
text.borderStyle = UITextBorderStyleRoundedRect;
text.textColor = [UIColor blackColor];
text.font = [UIFont systemFontOfSize:12.0];
text.backgroundColor = [UIColor clearColor];
text.keyboardType = UIKeyboardTypeDefault;
text.delegate = self;
[self.scroll addSubview:text];
yPosition_text += 90;
yPosition_result = yPosition_label + yPosition_text;
[self.scroll setContentSize:CGSizeMake(self.scroll.frame.size.width, yPosition_result)];
[self.view addSubview:self.scroll];
}
Now I created a dynamically created text fields and stored the answers entered by the user in the array as follows.
- (IBAction)save:(id)sender {
NSMutableArray *mutableTextArray = [[NSMutableArray alloc] init];
for(UITextField *field in self.scroll.subviews)
{
if([field isKindOfClass:[UITextField class]])
{
if([[field text] length] > 0)
{
[mutableTextArray addObject:field.text];
//NSLog(#"Save button 1 : %#", mutableTextArray);
//NSString *str = [str stringByAppendingString:[mutableTextArray objectAtIndex:0]];
//[self fetchStrings:mutableTextArray];
}
}
}
NSLog(#"Save button 2 : %#", mutableTextArray);
[self fetchStrings:mutableTextArray];
}
Now while posting the answer to another web service (web service 3 in my flow), I must pass slno, order, flag i get from web service 2 and the 'answer' that the user enters in the dynamically created field to the 'answer' key. How shall I get these 4 parameters [slno, order, flag (from web service 2) and answer (from dynamic text field)] to post to web service 3?
- (void) fetchStrings:(NSArray *)textArray
{
NSLog(#"Array string = %#", textArray); //I get the array that the user enters in the dynamically created text field here
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
NSUserDefaults *getDefaults = [NSUserDefaults standardUserDefaults];
NSString *uidObject = [getDefaults objectForKey:#"UIDKEY"];
NSString *str = [NSString stringWithFormat:#"{\"ProjID\": \"%#\",\"Uid\": \"%#\",\"EmailID\": \"%#\",", projectIdGobal, uidObject, emailFromLogin];
str = [str stringByAppendingString:#"\"ProjectInviterFQAnswers\": ["];
**for (SaveAsking *saveAsk in textArray) {
str = [str stringByAppendingString:[NSString stringWithFormat:#"{\"slno\":\"%#\",\"Answer\": \"%#\",\"order\": \"%#\", \"flag\": \"%#\"},", saveAsk.slno, saveAsk.answer, saveAsk.order, saveAsk.flag]]; // I want to save the parameters here
}**
// SaveAsking is a nsobject class where I have used a self created delegate for slno answer order and flag
str = [str stringByAppendingString:#"]}"];
NSLog(#"String is === %#", str);
NSURL *url = [NSURL URLWithString:#"some url"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *requestData = [str dataUsingEncoding:NSUTF8StringEncoding];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[request setValue:[NSString stringWithFormat:#"%d", [requestData length]] forHTTPHeaderField:#"Content-Length"];
[request setHTTPBody: requestData];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[connection start];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error){
if(error || !data)
{
NSLog(#"JSON Data not posted!");
[activity stopAnimating];
UIAlertView *alertMessage = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Data not saved" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertMessage show];
}
else
{
[activity startAnimating];
NSLog(#"JSON data posted! :)");
NSError *error = Nil;
NSJSONSerialization *jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
NSLog(#"Response is %#", jsonObject);
}
}];
}
Please do correct my flow if you understood what am i trying to achieve. Number for iterations in left box == number of iterations in right box and the result is in the middle box which needs to be posted to web service.

Try keeping a dictionary of the requests, where the key would be the dynamically created UITextField, and the value would be another dictionary with the values that you need to send.
So , when you create the textField, after adding it to the subview, create a dictionary with your values (sino, order, flag), and set that dictionary to the textfield.
When you are ready to send the data, you'll have a direct connection between the textField and the values for your webservice3.
