Question

Usually When i want a object to be accesed by many different event calls i just declare it in the h file.

However im making a app where i need to allow the user to create UILabels and drag and drop them where they want. So i have the code to make the labels and a alertview where they change the text.

-(IBAction)AddText{
UITextField *TextView;
TextView = [[UITextView alloc] initWithFrame:CGRectMake(40.0, 40.0, 40, 40)];
[self.view addSubview:TextView];

Which works however i need the user to be able to create many textviews which each have a unique name and a way i can reference them later such as TextView.text, doing it this way always creates a object named TextView and i can only reference it from his event, otherwise its undeclared.

Im really stuck at how i would go about doing this if anyone could help it would be great!,

Thanks

You could think about adding the newly created label to a NSMutableArray or, better, to a NSMutableDictionary. This latter solution gives you the possibility of creating a dictionary in which each label can be referred to using a string key. If you put such a dictionary in your .h file you’ll be fine, I think.
