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

NSMutableDictionary *requestDictionary = [[NSMutableDictionary alloc]
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 = [NSJSONSerialization dataWithJSONObject:requestDictionary
options:NSJSONWritingPrettyPrinted
error:nil];
NSString *jsonStr = [[NSString alloc]
initWithData:data encoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:@"http://192.168.1.51:82/test/handleRequest.php"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:60.0];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json"
forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json"
forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%lu",(unsigned long)jsonStr.length]
forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: data];
NSHTTPURLResponse* response =[[NSHTTPURLResponse alloc]init];
NSError*error = [[NSError alloc] init];
//synchronous
filling of data from HTTP POST response NSData
*responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response
error:&error];
//convert
data into string NSString*responseString = [[NSString alloc] initWithBytes:[responseData
bytes]
length:[responseData length]
encoding:NSUTF8StringEncoding];
NSLog(@"Response code %ld",(long)[response statusCode]);
NSLog(@"Response String %@",responseString);
