Add new place to Google Places - iphone

Question

I am new to IOS. I have to add new places to Google Places. I have referred this link https://developers.google.com/places/documentation/actions to add a place on button click, but I'm confused about passing parameters for this.
My coding lines are like this to fetch:
NSString *lat =#"-33.8669710";
NSString *longt =#"151.1957362";
gKey = #"my api key";
NSString *placeString = [NSString stringWithFormat:#"https://maps.googleapis.com/maps/api/place/add/json?sensor=false&key=%#HTTP/1.1Host:maps.googleapis.com {\"location\":{\"lat\":%#,\"lng\":%#},\"accuracy\": 50,\"name\":\"Gimmy Pet Store!\",\"types\":[\"pet_store\"],\"language\":\"en-AU\"}",gKey,lat,longt];
placeString = [placeString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSLog(#"Main Place Url: %#",placeString);
NSURL *placeURL = [NSURL URLWithString:placeString];
NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:placeURL];
[request setHTTPMethod:#"POST"];
NSURLConnection *placesConn =[[NSURLConnection alloc] initWithRequest:request delegate:self];

I have made following changes to my code & finally it is executed successfully...
//for setting Parameters to post the url.just change tag values to below line...
NSString *str1 = [NSString stringWithFormat:#"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?><PlaceAddRequest><location><lat>your latitude</lat><lng>your longitude</lng></location><accuracy>50</accuracy><name>place name</name><type>supported type</type><language>en-US</language></PlaceAddRequest>"];
NSLog(#"str1=====%#",str1);
NSString *str2 = [str1 stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSData *requestdata = [NSData dataWithBytes:[str2 UTF8String] length:[str2 length]];
NSString *postLength = [NSString stringWithFormat:#"%d", [requestdata length]];
//requesting main url to add new place to google places
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:#"https://maps.googleapis.com/maps/api/place/add/xml?sensor=false&key=your api key"]];
[request setValue:postLength forHTTPHeaderField:#"Content-Length"];
[request setValue:#"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[NSData dataWithBytes:[str1 UTF8String] length:[str1 length]]];
//NSURLConnection *placesConn =[[NSURLConnection alloc] initWithRequest:request delegate:self];
NSData *returndata = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnstr = [[[NSString alloc] initWithData:returndata encoding:NSUTF8StringEncoding] autorelease];
NSLog(#"returnstr: %#",returnstr);
& then i have decoded return response which i get i status as OK......:)
Any one can use above code...if any help require you can surely ask....:)
