I wanted to make an status indicator bar in Cocoa that I could switch between green, yellow, and red. Here’s how to do it with the NSIndicator control.
First add the control in Interface Builder and configure it as so:
Now you can use a call like the one below to change its color:
[statusIndicator setIntValue: 1]
Here is each value you can use and the corresponding status bar:
| 0 |  |
| 1 |  |
| 2 |  |
| 3 |  |
