iOS : How to correctly send put request to server - ios

Question

I have a put request that I am trying to achieve. The problem I am having is it isn't sending the correct raw body over to the server form/post parameter. What I am expecting is a raw body that is {"questions":[{"type":"control_head"}]}, instead I am getting questions[][type]=control_head any tips or suggestions are appreciated.
NSString *jsonString = #"{\"questions\":[{\"type\":\"control_head\"}]}";
[self createForms:jsonString];
- (void) createForms : (NSString *) form
{
[self executePutRequest:#"user/forms" params:form];
}
- (void) executePutRequest : (NSString *) url params : (NSString *) params
{
NSString *urlStr = [NSString stringWithFormat:#"http://requestb.in/13oujhot"];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSData *data = [params dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
NSMutableDictionary *userinfo = [[NSMutableDictionary alloc] init];
[manager PUT:urlStr parameters:json success:^(AFHTTPRequestOperation *operation, id responseObject) {
[operation setUserInfo:userinfo];
SBJsonParser *jsonparser = [SBJsonParser new];
id result = [jsonparser objectWithString:[operation responseString]];
if ( self.delegate != nil && [self.delegate respondsToSelector:finishSelector] ) {
[self.delegate performSelector:finishSelector withObject:result];
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
[operation setUserInfo:userinfo];
if ( self.delegate != nil && [self.delegate respondsToSelector:failSelector] ) {
[self.delegate performSelector:failSelector withObject:[operation error]];
}
}];
}

Copied From here
Updated again for AFNetworking 2.0 - see bottom
For AFNetworking 1.0:
NSURL *url = [NSURL URLWithString:#"https://mysite.com/"];
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
height, #"user[height]",
weight, #"user[weight]",
nil];
[httpClient postPath:#"/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSString *responseStr = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding];
NSLog(#"Request Successful, response '%#'", responseStr);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"[HTTPClient Error]: %#", error.localizedDescription);
}];
For AFNetworking 2.0 (and also using the new NSDictionary syntax):
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
NSDictionary *params = #{#"user[height]": height,
#"user[weight]": weight};
[manager POST:#"https://mysite.com/myobject" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON: %#", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", error);
}];

NSString *str_URL = [NSString stringWithFormat:#"YOUR URL"]];
NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:
Your Value,KEY_Name,
nil];
AFHTTPRequestOperationManager *Manager = [AFHTTPRequestOperationManager manager];
[Manager PUT:str_URL parameters:parameters
success: ^(AFHTTPRequestOperation *operation, id responseObject)
{
NSLog(#"%#", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error)
{
NSLog(#"%#", error.description);
}];
