Question

I have multiple UIViews, UIButtons etc. and would like to execute some specific code for each when i first use them.

For example for my UIButton *title, when i call title.frame for the first time, i would like first to call a setter that will verify that my button isn’t nill and if it is then alloc and init my button, set my title to @”TITLE” etc.

How can i do this ?

I am guessing you are talking about lazy initialization but that will require you to use the accessor method self.title.frame instead of title.frame. You can implement the getter method like this.

- (UIButton *)title {
    if ( !title ) {
        // Allocate the button
        // Set the button title
    }
    return title;
}
