Clearing TableView contents

Question

Can any one help me by providing code for how to clear all the table view cell contents. The tableview when a button is pressed gets reloaded but does not get cleared

Thanks Rakesh

Solution 1

For clearing a tableView, you just remove all objects from the array that is populating your table and you reload the tableView after that.

[myArray removeAllObjects];
[self.tableView reloadData];

Solution 2

Set a bool tableIsEmpty and set the number of rows in the tableview to either 0 (table is empty) or the arrays count according to this BOOl in

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;

Of cousre you have to set tableIsEmpty = YES, when the button is pressed and to NO again when theres data loaded. Then call

[self.tableView reloadData];

Not tested but should work shouldnt it?

Solution 3

You can just add one variable as flag before reloading the table.

makeEmpty = YES;
[tableview reloadData];
makeEmpty = NO;

Then in the tableview delegate method

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {
  if(makeEmpty)
      return 0;
 }
