Displaying UITableView in proper format - ipad

Question

I have the following code to fetch the data from URL, store it in arrays, and display it inside the table.
I had some issue related to fetching and that is solved on SO Click here
Now the issue is data is displayed in the table in a manner which is not the ideal one.
When I run the below code, I get this output. That shaded grey portion is my main concern.
When I try to insert any element say button in that grey shaded area through design view, it gets overlapped by table.
If I change
aTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen]applicationFrame] style:UITableViewStyleGrouped];
with
aTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen]applicationFrame] style:UITableViewStylePlained];
I get the table output without the grey shadow but it's way too simple.
Note that I'm creating table programmatically.

THANKS IN ADVANCE

Answer 1

If your problem is to remove the lightgrey area from your groupedtableview, then you can remove the shaded grey area by adding this to your code:
if ([myTable respondsToSelector:#selector(backgroundView)]) {
myTable.backgroundView = nil;
}
It's an issue that only iPad has with groupedTableViewStyle.

Answer 2

At first of all why you are writing this line two times?? [super viewDidLoad]; in tableview
Secondly i think you are displaying your fetch data into an webview which is into the table view.i do not understanding that if you are making your table pro grammatically then how could you display webview using IBOutlet into the tablevie?!!
I think you can try this[webView setOpaque:NO]; May be it will solve the problem..
