Array of NSButton

Question

I wonder if I can do something like

IBOutlet NSButton * aButton[100];

It turns out that aButton cannot be seen in the interface builder.

My app has lots of buttons and I want to see if there are way I can use looping to iterate the state of all buttons.

Answer 1

No, you can't use an array as an outlet. Some options:

• create a NSButton subclass that does what you want to do
• walk the view hierarchy at runtime to find the buttons

OTOH, if your UI has 100 buttons, you've probably got bigger problems...

Answer 2

IB doesn't handle arrays. You can add them using a loop in your code instead.

Answer 3

You may find an NSMatrix of NSButtonCells easier to work with, and unlike a C array of NSButtons, you can create one in IB.
