Q:

My Application Crashes While Reloading table data

My Application Crashes when it reloads UITableView data in ViewDidAppear . It works fine till the number of entries in table is less than 20 but once it goes above that it Crashes where Ever and whenever i call 
    [tableview reloadData];

A:

It's almost certainly a discrepancy between the value returned from the UITableViewDataSource method:
tableView:numberOfRowsInSection:
and the call to:
tableView:cellForRowAtIndexPath:
Where tableView:numberOfRowsInSection: is returning more rows than tableView:cellForRowAtIndexPath: can provide.
However you don't provide enough information to help further.
