Adding buttons to a UITableView cell - ios

Question

I am trying to add buttons to my UITableView cells, using code like below:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
UIButton *button = self.buttons[0];
[cell addSubview:button];
return cell;
}
The button isn't showing though. Is it possible to add buttons to a cell like this or do I have to make a custom UITableViewCell class?
When the button was made for the array the frame was set like below:
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 70, 70)]

Answer 1

The usage for adding elements have changed somewhen. Use
[cell.contentView addSubview:button];
and don't forget to proof before if a button is already added :P
enum
{
kButtonForA = 3333 // example
};
for every button set
button.tag = kButtonForA;
and use them
UIButton* btn = (UIButton *)[cell.contentView viewWithTag:kButtonForA];
if(!button)
btn = self.buttons[i];
UPDATE
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if(!self.buttons || [self.buttons count] == 0)
return 0;
return ...;
}
and after you init your array, use
[tableView reloadData];
just one possible way, but a fast one

try this in your - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if ([cell.contentView viewWithTag:100] == nil) {
button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(130,25, 40.0, 40.0);
[button setTitle:#"+" forState:UIControlStateNormal];
[button addTarget:self action:#selector(aMethod:)
forControlEvents:UIControlEventTouchUpInside];
button.tag=100;
[cell.contentView addSubview:button];
}
then perform action
-(void)aMethod:(id)sender {
NSInteger tag=[[sender superview] tag];
//NSInteger value=[[self.qtt objectAtIndex:tag] integerValue]+1;
//[self.qtt replaceObjectAtIndex:tag withObject:[#(value) stringValue]];
//[self.mytableview reloadData];
}
