selector for multiple uibuttons in uitableviewcell - ios

Question

I'm adding the same selector for multiple UIButtons which are part of a UITableViewCell and it works only for the first one. Am I missing something?
Here's my code:
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
NSDictionary *d = [tableData objectAtIndex:indexPath.row];
NSArray *answers = [d objectForKey:#"answers"];//array of { id = 35; text = "\U03c4\U03a\U03c0\U03bf\U03c4\U03b1"; }
UILabel *startDate = (UILabel *)[cell viewWithTag:100];
long long startDateEpoch = [[d objectForKey:#"startDate"] longLongValue];
NSDate *sDate = [NSDate dateWithTimeIntervalSince1970:startDateEpoch/1000];
NSDateFormatter *startDateFormatter = [[NSDateFormatter alloc] init];
[startDateFormatter setDateFormat:#"dd/MM/yyyy"];
startDate.text = [startDateFormatter stringFromDate:sDate];
((UILabel *)[cell viewWithTag:101]).text = [d objectForKey:#"subject"];
NSArray *tags = [d objectForKey:#"tags"];
((UILabel *)[cell viewWithTag:102]).text = [tags componentsJoinedByString:#" "];
NSString *imageURL = [d objectForKey:#"media"];
UIImageView *iv = (UIImageView *)[cell viewWithTag:103];
iv.contentMode = UIViewContentModeScaleAspectFit;
[iv sd_setImageWithURL:[NSURL URLWithString:imageURL]
placeholderImage:[UIImage imageNamed:#"placeholder.png"]];
UIView *buttonsContainer = (UIView *)[cell viewWithTag:104];
for(UIView *vv in buttonsContainer.subviews){
[vv removeFromSuperview];
}
int index = 0;
NSLog(#"buttonsContainer children: %d", buttonsContainer.subviews.count);
for(NSDictionary *answer in answers){
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, index * 40 + (index+1)*5, [UIScreen mainScreen].bounds.size.width, 40)];
v.backgroundColor = [UIColor whiteColor];
CGRect labelFrame = v.frame;
labelFrame.origin.y = 0;
UILabel *l = [[UILabel alloc] initWithFrame:labelFrame];
l.text = (NSString *)[answer objectForKey:#"text"];
l.textAlignment = NSTextAlignmentCenter;
UIView *bottomLine = [[UIView alloc] initWithFrame:CGRectMake(0, v.frame.size.height - 1, v.frame.size.width, 1)];
bottomLine.backgroundColor = [UIColor colorWithRed:238.0/255.0 green:205.0/255.0 blue:103.0/255.0 alpha:1.0];
UIButton *b = [[UIButton alloc] initWithFrame:v.frame];
[b addTarget:self action:#selector(answered:) forControlEvents:UIControlEventTouchUpInside];
[v addSubview:l];
[v addSubview:bottomLine];
[v addSubview:b];
[buttonsContainer addSubview:v];
index++;
}
}
So for example if 4 buttons are added, the selector is called only when I click on the first one. When I click on the other three nothing happens.
EDIT:
adding the answered: code:
- (void)answered:(UIButton *)sender
{
NSLog(#"#answered");
}

ok, I found it. Many cudos to TomSwift since his point gave me the idea to place borders on all the views in order to debug their frames size and origin.
Notice that I give to my buttons the same frame as their superviews, which is wrong since they should not have the same origin. The buttons' origin should be 0,0 since they have the same frame size as their superviews.
lessons learn for noobs like me:
When a button does not work, place borders in order to make sure their frame is within the superview's bounds.
Do not assign the same frame on a view and its subview. It will place it outside of the superview's bounds which in 92% of the cases brings undesirable behaviour.
