Question

I am having trouble telling my table view which NSURLRequest it should target. I can get a basic table view to load with a single query, but am trying to make it pull the json string from a different URL if certain segmented controls are active.

These first three lines of code work by themselves

NSString *urlA1 = [NSString stringWithFormat:@"http://www.website.com/json_books.php?
item_id=%@",itemId];

NSURL *urlA2 = [NSURL URLWithString:urlA1];

NSURLRequest *requestA = [NSURLRequest requestWithURL:urlA2];
[[NSURLConnection alloc] initWithRequest:requestA delegate:self];

However, if I include the following three lines after the first three, the tableview loads the json from the first NSURLRequest, then immediately flickers and shows content from the string below:

NSString *urlB1 = [NSString stringWithFormat:@"http://www.website.com/json_movies.php?
item_id=%@",itemId];

NSURL *urlB2 = [NSURL URLWithString:urlB1];

NSURLRequest *requestB = [NSURLRequest requestWithURL:urlB2];
[[NSURLConnection alloc] initWithRequest:requestB delegate:self];

I am pulling the result into the table view with these lines of code:

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse 
*)response
{
    data = [[NSMutableData alloc] init];
}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)theData
{
    [data appendData:theData];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

    items = [NSJSONSerialization JSONObjectWithData:data options:nil error:nil];
    [mainTableView reloadData];
}

Does anyone know why I am unable to specify which NSURLRequest I would like the tableview to target? Thank you!

Do you Want to Show Data from Both The URL ?

if yes then You have to take NSMUtableArray and initialize the Array in ViewDidload before Firing the Request. And You have to Add the Objects into the Array from Each URL.

Example:

[DataArray addObject:@"Yourdata"];

[Yourtable reloadData];

If You need to Separate the data as per Segmented Control then Save Your data in Separate Array.

MyfirstArray= @"Data from URL 1";

MySecondArray= @"Data from URL 2";


-(IBAction)SegmentChange:(Id)sender
{
if(segmented.selectedSegmentIndex==0)

{
items=MyfirstArray;

[mytable reloadData];

}

else

{
items=MysecondtArray;

[mytable reloadData];
}

}

Also You can take Switch statement.
