//Button Click
BBAuthorViewController *BBAuthor =[[UIStoryboard storyboardWithName:#"Main" bundle:nil]instantiateViewControllerWithIdentifier:#"BBAuthor"];
BBAuthor.authorDetail=_adDetailsObj.authorDetail;
[self.navigationController pushViewController:BBAuthor animated:YES];
//Json
+(NSDictionary *)sendPostRequest:(NSDictionary *)params toUrl:(NSString *)urlString
{
NSMutableString *paramString =
[NSMutableString stringWithString:#""];
NSArray *keys = [params allKeys];
for (NSString *key in keys) {
[paramString appendFormat:#"%#=%#&",key,
[params valueForKey:key]];
}
NSString *postString = #"";
if ([paramString length] > 0)
postString = [paramString substringToIndex:
[paramString length]-1];
NSMutableURLRequest *request =[NSMutableURLRequest
requestWithURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
[request setHTTPBody:[postString
dataUsingEncoding:NSUTF8StringEncoding]];
NSURLResponse *res;
NSError *error;
NSData *resp = [NSURLConnection sendSynchronousRequest:request
returningResponse:&res error:
&error];
NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)res;
int statusCode;
statusCode = [httpResponse statusCode];
NSDictionary *jsonArray = [NSJSONSerialization JSONObjectWithData:resp options:NSJSONReadingMutableContainers error:&error];

str = [BBServerJson sendPostRequest:json toUrl:url];
//Tableview
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

return str.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

cell=[tableView dequeueReusableCellWithIdentifier:#"cell"];
NSArray *array = [str objectForKey:#"results"];
NSDictionary *dic= [array objectAtIndex:indexPath.row];
cell.textLabel.text = [dic objectForKey:#"author_name"];
return cell;

I think you are returning wrong row count in numberOfRowsInSection: method.
Change the return statement to,
return [[str objectForKey:#"results"] count];
