Delete button on UIWebView - ios

Question

Im getting touch location coordinates from UIWebView and displays the button with coordinates. It's working with coordinates match. So, i need to increase the button. I didn't use Array for button. When i delete particular button from UIWebView it delete all the button. Shall i use NSMutableArray?. Here x & y is the touch point coordinates in float value
if(x && y){
NSLog(#"x is %f",x);
NSLog(#"y is %f",y);
button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button1 addTarget:self
action:#selector(click1:)
forControlEvents:UIControlEventTouchDown];
[button1 setTitle:#"click" forState:UIControlStateNormal];
button1.frame = CGRectMake(x, y, 30.0, 20.0);
// [btnArray addObject:button1];
button1.tag = gTag;
gTag++;
[wbCont.scrollView addSubview:button1];
}
Delete the button:
-(void)recycle:(id)sender{
for(int i=1;i<gTag;i++){
[[wbCont.scrollView viewWithTag:i] removeFromSuperview];
}

-(void)click1:(id)sender{
UIButton *mainBtn = (UIButton *)sender;
int mainTag = mainBtn.tag;
txtview = [[UITextView alloc]initWithFrame:CGRectMake(0,0,320,568)];
txtview.font = [UIFont fontWithName:#"Helvetica" size:12];
txtview.font = [UIFont boldSystemFontOfSize:12];
txtview.backgroundColor = [UIColor whiteColor];
txtview.scrollEnabled = YES;
txtview.pagingEnabled = YES;
txtview.editable = YES;
txtview.tag = mainTag*1000;
for(int i=0; i<[textArray count];i++){
txtview.text=[textArray objectAtIndex:i];
}
[self.view addSubview:txtview];
button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self action:#selector(done:) forControlEvents:UIControlEventTouchDown];
[button setTitle:#"Done" forState:UIControlStateNormal];
button.frame = CGRectMake(240.0, 20.0, 60.0, 40.0);
[txtview addSubview:button];
recyclebtn=[UIButton buttonWithType:UIButtonTypeCustom];
recyclebtn.tag = mainBtn.tag;
[recyclebtn addTarget:self action:#selector(recycle:) forControlEvents:UIControlEventTouchDown];
[recyclebtn setImage:[UIImage imageNamed:#"recycle.png"] forState:UIControlStateNormal];
recyclebtn.frame=CGRectMake(0, 10, 30, 30);
[txtview addSubview:recyclebtn];
}
-(void)recycle:(id)sender {
UIButton *btnTemp = (UIButton *)sender;
[[wbCont.scrollView viewWithTag:btnTemp.tag] removeFromSuperview];
int txtTag = btnTemp.tag*1000;
[[self.view viewWithTag: txtTag] removeFromSuperview];
