I am creating an application that need to have a progress window in which i want to dynamically insert a subview for each item being processed, like Finder's copy files panel window. And also remove it dynamically when processing is done.
I want to use the same NSViewController view for all sub views, and I'm using an NSStackView to manage the views.
But, to make the sub views stay in memory I have to keep a strong reference to them, and the only way I know of is to create a property for each sub view i need to display. Like this:
@propery (strong) NSViewController *myViewController1;
@propery (strong) NSViewController *myViewController2;
@propery (strong) NSViewController *myViewController3;
@propery (strong) NSViewController *myViewController4;
....
I would like to know if there is a better, more dynamic way of doing this? Or do I have to create x number of properties for sub views to know i have enough instances to allocate, because I can't tell how many process views the user will need when running the application and exporting items.
I would therefore like to dynamically allocate each subview AND create a strong reference to it. Is that possible? Or is there another way of doing what I want?
Please let me know if I'm being unclear, I'll gladly explain more to get help with this problem.
You can store the references to the view controllers in an NSArray. Arrays keep strong references to the objects which they contain.
