Why my button in a UItableView didn't respond? - uitableview

Question

I've a UItableView with multiple section, In Each section, I've a View which contains a button, and in each of these sections one row is located but I've hided that row.
In short, my tableview is a collection of sections which in turns contains buttons on each section, when I click on the button it didn't respond but once I scroll ,my table from bottom to top the buttons are responded. What is the issue here?
Thanks!
Here is the code:
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
sheettable.scrollsToTop=YES;
UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 22)];
CGRect rect= CGRectMake(0, 0, 320,40);
UIBezierPath *maskPath;
maskPath = [UIBezierPath bezierPathWithRoundedRect:rect byRoundingCorners:(UIRectCornerAllCorners) cornerRadii:CGSizeMake(5.0, 5.0)];
CAShapeLayer *maskLayer = [[CAShapeLayer alloc] init];
maskLayer.frame =rect;
maskLayer.path = maskPath.CGPath;
headerView.layer.mask = maskLayer;
headerView.backgroundColor=[UIColor greenColor];
UITextField *label1 = [[UITextField alloc] init] ;
label1.delegate=self;
label1.frame = CGRectMake(5, 1, 200, 35);
label1.font = [UIFont boldSystemFontOfSize:16];
label1.text = [[result2 objectAtIndex:section] objectForKey:#"cat_desc"];
UIButton *btn=[[UIButton alloc]init];
btn.frame=CGRectMake(5, 1, 200, 35);
btn.tag=section;
btn.backgroundColor=[UIColor clearColor];
[headerView addSubview:label1];
[btn addTarget:self action:#selector(selectedsections) forControlEvents:UIControlEventTouchUpInside];
[headerView addSubview:btn];
cameracategory=section;
return headerView;
}
-(void)selectedsections
{
if(cameracategory==0)
{
NSLog(#"At Index");
}
if(cameracategory==1)
{
NSLog(#"At Index");
}
if(cameracategory==2)
{
NSLog(#"At Index");
}
if(cameracategory==3)
{
NSLog(#"At Index");
}
if(cameracategory==4)
{
NSLog(#"At Index");
}
}

I tested your code, it works, but I created the UITableView myself. You should check that. Also try to write more readable code :) it will be more easier in the future :)
You have some misaligned frames (subviews are bigger than parent).
- (void)sectionButtonAction:(UIButton *)sender {
NSLog(#"Section button tapped: %i", sender.tag);
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
CGRect tableRect = tableView.frame;
CGRect headerRect = CGRectZero;
headerRect.size.width = tableRect.size.width;
headerRect.size.height = 22;
CGRect bezierRect = CGRectZero;
bezierRect.size.width = tableRect.size.width;
bezierRect.size.height = 44;
CAShapeLayer *maskLayer = [CAShapeLayer layer];
[maskLayer setFrame:bezierRect];
[maskLayer setPath:[UIBezierPath bezierPathWithRoundedRect:bezierRect byRoundingCorners:UIRectCornerAllCorners cornerRadii:CGSizeMake(5, 5)].CGPath];
UIView *headerView = [[UIView alloc] initWithFrame:headerRect];
[headerView setBackgroundColor:[UIColor greenColor]];
[[headerView layer] setMask:maskLayer];
CGRect labelRect = CGRectZero;
labelRect.origin.x = 5;
labelRect.origin.y = 1;
labelRect.size.width = 200;
labelRect.size.height = 35;
UILabel *headerLabel = [[UILabel alloc] initWithFrame:labelRect];
[headerLabel setFont:[UIFont boldSystemFontOfSize:16]];
[headerLabel setText:#"asd"];
[headerView addSubview:headerLabel];
CGRect buttonRect = labelRect;
UIButton *headerButton = [UIButton buttonWithType:UIButtonTypeCustom];
[headerButton setFrame:buttonRect];
[headerButton setTag:section];
[headerButton addTarget:self action:#selector(sectionButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[headerView addSubview:headerButton];
return headerView;
}
