Following is the Objective-C code to post json data in iOS -


NSMutableDictionary *requestDictionary = [[NSMutableDictionaryalloc] init];
[requestDictionary setObject:@"Robert"forKey:@"firstName"];
[requestDictionary setObject:@"Abraham"forKey:@"lastName"];
[requestDictionary setObject:@"robertab1999@gmail.com"forKey:@"email"];
[requestDictionary setObject:@"pass1234"forKey:@"password"];
NSData *data = [NSJSONSerializationdataWithJSONObject:requestDictionary options:NSJSONWritingPrettyPrintederror:nil];
NSString *jsonStr = [[NSStringalloc] initWithData:data encoding:NSUTF8StringEncoding];
NSURL *url = [NSURLURLWithString:@"http://192.168.1.51:82/test/handleRequest.php"];
NSMutableURLRequest *request = [NSMutableURLRequestrequestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicytimeoutInterval:60.0];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json"forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json"forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSStringstringWithFormat:@"%lu",(unsignedlong)jsonStr.length] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: data];
NSHTTPURLResponse* response =[[NSHTTPURLResponsealloc]init];
NSError*error = [[NSErroralloc] init];
//synchronous filling of data from HTTP POST response NSData *responseData = [NSURLConnectionsendSynchronousRequest:request returningResponse:&response error:&error];
//convert data into string NSString*responseString = [[NSStringalloc] initWithBytes:[responseData bytes] length:[responseData length] encoding:NSUTF8StringEncoding];
NSLog(@"Response code %ld",(long)[response statusCode]);
NSLog(@"Response String %@",responseString);
