Question

- (int)indexOfView:(id)view {
    for(int i = 0; i < self.subviews.count; ++i) {
        UIView *v = [self.subviews objectAtIndex:i];
        if(v == view) return i;
    }

    return -1;
}

This always returns -1. I suspect the problem is with v == view. Is that incorrect?

Answer 1

If it always returns -1, then it’s not in there.

But you should throw away a few lines of code:

[self.subviews indexOfObject:view]

NSArray and its methods are your friend. The indexOfObject: method will return NSNotFound in stead of -1.

If it’s a subclass of one of the contained views, then it won’t show up. Particularly if you’re dealing with an NSTableViewCell.
