Question

I want to send JSON data in URL body from my IOS app to server.I searched many SO question but i can't find what i want. If anyone knows how to do with AFNetworking then please let me know.Thanks
This is my code snipped which send parameters
NSMutableDictionary *parameters = [[NSMutableDictionary alloc]init];
[parameters setValue:#"PY" forKey:#"AppSecret"];
[parameters setValue:#"IOS" forKey:#"login_provider"];
[parameters setValue:_txtemail.text forKey:#"email"];
[parameters setValue:_txtpassword.text forKey:#"password"];
[parameters setValue:#"1" forKey:#"ios_device_id"];
AFHTTPSessionManager *managertwo = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
managertwo.requestSerializer = [AFJSONRequestSerializer serializer];
[managertwo.requestSerializer setValue:#"application/json" forHTTPHeaderField:#"Content-Type"];
[managertwo POST:[NSString stringWithFormat:#"http://capemedics.co.za/Api/user_register/valid_user"] parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
NSLog(#"success! %#",responseObject);
NSLog(#"%#",parameters);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(#"error: %#", error);
}];
And i am getting error in it. I want to pass JSON data like this in URL Body
{"login_provider": "IOS","email": "%#","password": ”%#“,”ios_device_id": "1"}

Try This
NSString *strData = [[NSString alloc] initWithFormat:#"{\"login_provider\": \"IOS\",\"email\": \"%#\",\"password\": \"%#\",\"ios_device_id\": \"1\"}",self.txtEmail.text,self.txtPassword.text];
NSString *strURL = #"http://capemedics.co.za/Api/user_register/valid_user"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:strURL] cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10];
[request setHTTPMethod:#"POST"];
[request setValue: #"YOUR_KEY" forHTTPHeaderField: #"AppSecret"];
[request setValue: #"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody: [strData dataUsingEncoding:NSUTF8StringEncoding]];
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)
{
if (responseObject)
{
}
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error){
}];
[op start];

It worked before not sure
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL
cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:10];
[request setHTTPMethod:#"POST"];
[request setValue: #"application/json" forHTTPHeaderField:#"Content-Type"];
[request setHTTPBody: [body dataUsingEncoding:NSUTF8StringEncoding]]; /// body is your son string
AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(#"JSON responseObject: %# ",responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Error: %#", [error localizedDescription]);
}];
[op start];
