Question

I am disabling and enabling a view using the following code….

[self.view setUserInteractionEnabled:NO];
[self.view setUserInteractionEnabled:YES];

If I do like this, all it subviews also got affected… All are disabled, how do I do only for particular view? Is it possible?

Answer 1

It’s exactly the same, assuming your other view is either a member or you can iterate through self.view‘s array of subviews, like so:

MyViewController.h

UIView* otherView;

MyViewController.m

otherView.userInteractionEnabled = NO; // or YES, as you desire.

OR:

for (int i = 0; i < [[self.view subviews] count]; i++)
{
    UIView* view = [[self.view subviews] objectAtIndex: i];

    // now either check the tag property of view or however else you know
    // it's the one you want, and then change the userInteractionEnabled property.
}
