Event not triggered for UIButton in UIView in UITableViewCell - objective-c

Question

In my UITableViewCell I have an UIImageView with a UIButton.
Here my code
My problem is that each time I try to click on the UIButton the UITableViewCell is triggered by the TouchUpInside event and not the UIBUtton.
Can you please help me?

Answer 1

This is my code.. here I use a UIButton inside the UITableViewCell and it works perfectly for me.. Hope this will help you..
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = #"ChildList";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
itsChildContactsTableView = tableView;
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
}
// we need a view to place our labels on.
UIView *aTableCellContentView = [[UIView alloc] initWithFrame:CGRectZero];
CGRect contentRect = aTableCellContentView.bounds;
CGFloat boundsX = contentRect.origin.x;
CGRect frame;
frame = CGRectMake(boundsX + 10, 8, 200, 20);
UIButton *aCallButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aCallButton setImage:[UIImage imageNamed:#"call.png"] forState:UIControlStateNormal];
[aCallButton addTarget:self action:#selector(dialNumber:) forControlEvents:UIControlEventTouchUpInside];
[aCallButton setTag:[indexPath row]];
frame = CGRectMake(210, 14, 35, 35);
aCallButton.frame = frame;
UIButton *aEmailButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aEmailButton setImage:[UIImage imageNamed:#"mail.png"] forState:UIControlStateNormal];
[aEmailButton addTarget:self action:#selector(eMailContact:) forControlEvents:UIControlEventTouchUpInside];
[aEmailButton setTag:[indexPath row]];
frame = CGRectMake(250, 14, 35, 35);
aEmailButton.frame = frame;
aTableCellContentView.backgroundColor = [UIColor whiteColor];
[cell.contentView addSubview:aCallButton];
[cell.contentView addSubview:aEmailButton];
[cell.contentView addSubview:aTableCellContentView];
[aTableCellContentView release];
return cell;
}

if your UITableViewCell has a customer height(not the default 44.0f)。 if so, you should set the code like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellID = #"cellID";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
cell.contentView.frame = CGRectMake(0, 0, tableView.width, [self tableView:tableView heightForRowAtIndexPath:indexPath]);
// add a UIButton that you create
}
return cell;
}
the reason for this problem is the cell.contentView.size is default (320.f, 44.0f), if your button is over the rect, then the button could not accept the event, so you should set the cell.contentView.frame yourself, like i do the code。
Good Luck。
