Answer 1

I think you need to remove this code in your method buttonTouchUpInside
_label =[[UILabel alloc]initWithFrame:CGRectMake(x,y, 200.0f, 30.0f)];
_label.tag = index;
[self.view addSubview:_label];
because you are adding new label at same frame
And write this method like this way
- (IBAction)buttonTouchUpInside:(id)sender{
y = y - 40;
UIButton *button = (UIButton*)sender;
NSInteger index = button.tag;
[[sender viewWithTag:index] removeFromSuperview];
_label = (UILabel *)[self.view viewWithTag:index];
[_label removeFromSuperview];
_label = (UILabel *)[self.view viewWithTag:index + 1];
_label.frame = CGRectMake(x,y, 200.0f, 30.0f);
_label.tag = index;
_button = (UIButton *)[self.view viewWithTag:index+1];
_button.frame = CGRectMake(220.0f,y, 30.0f, 30.0f);
_button.tag = index;
_button.backgroundColor =[UIColor blueColor];
}
No need this statement
[self.view addSubview:_label];
[self.view addSubview:_button];
once you added in your view
