how to add values from nsstrings in iOS? - button

Question

I have 5 buttons. Each button has some value like 1,2,3,4,5 in a string named totalSeats_selected.
I want to save them into a nsstringthat shows result like this:
nsstring * result = [1,2,3,4,5];
These values are to used as request for a web service, so it must be in this format to send total number of seats?
So, how to save all these values in nsstring on button event?

Answer 1

Use like this.Suppose your string is in integer means use Method 1 .otherwise use Method 2(If your value assigned in NSString).
Method 1:
- (IBAction)Savebtnpressed:(id)sender {
NSMutableDictionary *datadict=[NSMutableDictionary dictionary];
[datadict setValue:[NSNumber numberWithInt:[first intValue]] forKey:#"1"];
[datadict setValue:[NSNumber numberWithInt:[second intValue]] forKey:#"2"];
[datadict setValue:[NSNumber numberWithInt:[third intValue]] forKey:#"3"];
[datadict setValue:[NSNumber numberWithInt:[fourth intValue]] forKey:#"4"];
[datadict setValue:[NSNumber numberWithInt:[fifth intValue]] forKey:#"5"];
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:datadict options:kNilOptions error:nil];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSURL *someURLSetBefore =[NSURL URLWithString:#" url "];
[request setURL:someURLSetBefore];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
// [request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
// [request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setHTTPBody:jsonData];
NSError *error;
NSURLResponse *response;
NSData *responseData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString * string1=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"%#",string1);
}
}
Method 2:
- (IBAction)Savebtnpressed:(id)sender {
NSMutableDictionary *datadict=[NSMutableDictionary dictionary];
[datadict setObject:[NSString stringWithFormat:#"%#",FIRST] forKey:#"1"];
[datadict setObject:[NSString stringWithFormat:#"%#",SECOND] forKey:#"2"];
[datadict setObject:[NSString stringWithFormat:#"%#",THIRD] forKey:#"3"];
[datadict setObject:[NSString stringWithFormat:#"%#",FOURTH] forKey:#"4"];
[datadict setObject:[NSString stringWithFormat:#"%#",FIFTH] forKey:#"5"];
NSData* jsonData = [NSJSONSerialization dataWithJSONObject:datadict options:kNilOptions error:nil];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
NSURL *someURLSetBefore =[NSURL URLWithString:#" url "];
[request setURL:someURLSetBefore];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"Content-Type"];
// [request setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
// [request setValue:#"application/json" forHTTPHeaderField:#"Accept"];
[request setHTTPBody:jsonData];
NSError *error;
NSURLResponse *response;
NSData *responseData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString * string1=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding];
NSLog(#"%#",string1);
}
}
