Question

I have added a UIScrollVIew using IB. Then using the following code i add a few buttons to this UIScrollView.

for (int index=0; index<3;index++)
{
    UIButton* button=[UIButton buttonWithType:UIButtonTypeRoundedRect];

    [button setTitle:buttonTitle forState:UIControlStateNormal];
    [button setFrame:CGRectMake(18,200,300,45)];
    [button setTag:100+index];
    [button addTarget:self action:@selector(butclick:) forControlEvents:UIControlEventTouchUpInside];
    [self.scrollView addSubview:button];
}

Now i need a way to remove these buttons which i added from the ScrollView.

note: There are other buttons, images, labels attached to the UIScrollView. And those should not be removed. It’s only the buttons that i added programatically should get removed from the UIScrollView.

Answer 1

Put a tag on those buttons, then you can take them again using:

for (int index=0; index<3;index++)
{
    UIButton *myButton = (UIButton *)[self.scrollView viewWithTag:100+i];
    [myButton removeFromSuperView];
}

Or save those buttons in an array, and then you can do the same.

And if you just want to hide them, you can do:

myButton.hidden = YES;
