Question

Previously, I generate the programme using code, and I have a super class that have a background image all the time. But now I change my coding to using XIB, how can I insert a view after the Nib is loaded? But I don’t want all my XIB have a view. Thanks.

awakeFromNib is the right method to use. You don’t want to cover up views by just adding the subview. Insert the subview instead.

- (void)awakeFromNib
{
    UIView *targetView;
    UIView *viewToInsert = [self pointerToViewToInsert];

    for (UIView *aSubview in self.view.subviews){
         if ([aSubview isEqual:self.someView]){
             targetView = aSubview;
             break;
         }
    }
    if (targetView){
        int targetIndex = [self.view.subviews indexOfObject:targetView];
        [self.view insertSubview:viewToInsert atIndex:targetIndex];
}
