So I have a function that does something, uses NSTimer to pause for a short time and repeat. During that loop, i want my NSView to update, is there any way to do this?

Thanks

Supposing that you are overriding the drawRect method to implement the drawing, you could simply pass the NSView instance the display message. Since all NSViews have this it can be used to force a redraw directly (it is usually invoked indirectly by setNeedsDisplay, or something).

Example:
[myNSView display];

You should be able to call this directly from the NSTimer but I am not sure. Another topic discussed this and there was talk that it could not find it since it is not defined in your specific subclass. In that case just make something that calls display.

Example:
-(void)thingThatDoesStuff
{
[self display];//if this is being defined in the same class as the NSView subclass you are using or...
[myNSView display];//if you are defining this NSTimer "target" in another class.
}

Hope that helps,
Jeff.

Be careful calling display from the Timer. Most of the time it will work correctly, but is possible that your application will hang because the window drawing code is not thread safe. There are two cases:

If the timer is in the main thread, then you could have an error if another method tried to display the same view. This is pretty easy to avoid.

If the timer is in a separate thread, you'll have lots of errors. You would have a problem, for example, if the timer fired just as the user clicked on a menu.

Calling setNeedsDisplay(inRect) is much safer.
