In short you can delete selected Row with clicking UIbutton like bellow:-

-(IBAction)Acceptrequest:(id)sender
{
UIButton *btn =(UIButton*)sender;

[myarray removeObjectsAtIndexes:btn.tag];
[tableView deleteRowsAtIndexPaths:myarray withRowAnimation:UITableViewRowAnimationAutomatic];

[tableVIew reloadData];
}

getting this error /Users/mobitsolutions/Desktop/adnan/BedSpace/RequestViewController.m:64:6: No visible @interface for 'NSArray' declares the selector 'removeObjectsAtIndexes:' on this line [myarray removeObjectsAtIndexes:btn.tag];

myarray = [NSMutableArray array]

I suggest you to go to iOS documentation and read more about use of arrays. The flow is simple: you add to array A the index paths you want to delete, then in tableview you remove those rows. In array B (datasource) you remove the index.

You need to implement this method:

[tableView deleteRowsAtIndexPaths:arrayOfIndexPathsToDelete withRowAnimation:UITableViewRowAnimationAutomatic];

It has to be NSMutableArray instead of NSArray
