macOS NSTimer help...

[ledd]

So I have an application that I have developed in a NSDocument. I want to be able to have it do an update on a timer which I think understand how to implement.

The only problem is I am not familiar with where the NSTimer function would be continuously called every lets say 1 second?

I have a MyDocument.m file which contains my UpdateUI function which is what I would want the NSTimer to call.

And then I also have my main.h file which simply has

#import <Cocoa/Cocoa.h>

int main(int argc, char *argv[])
{
    return NSApplicationMain(argc, (const char **) argv);
}

Thanks.

I apologize for the unnecessary thread I figured it out.

Awesomely enough for those who don't know you can just start the timer from any function call. I don't really know why I thought this would not work. I guess I thought there was maybe a standard that should be upheld to where you should make the NSTimer.

I've run into another minor issue that I am struggling with.
So I have a button that I want to change the text of when it is clicked....

So I have...
NSButton* calculate;

So I figured I could do...
[calculate setTitle: @"New Title"];

But this didn't appear to work. Did I do something wrong?
Thanks.

How is the button created? Is it an IBOutlet connected in Interface Builder?

 

[ledd]

Yah its an IBOutlet NSButton and then the calculate functions is an IBAction that is connected to the NSButton

Could you post a bit more code? What does your complete -calculate: method look like?

 

[ledd]

Ok... lets see if I can appropriately map this out

I have a button in my window... In the InterfaceBuilder I have declared an IBOutlet for the button called stopStartBtn in the Inspector
In my .h I have

IBOutlet NSButton* stopStartBtn

and a method

- (IBAction)startStopCounter:(id) sender;

The startStopCounter method is as follows

- (IBAction)startStopCounter:(id)sender
{	
	if(timer == nil){
		[self startTimer];
		[startStopBtn setTitle: @"Pause"];
	}
	else{
		[self stopTimer];
		[startStopBtn setTitle: @"Start"];
	}
}

The functions startTimer and stopTimer work great but the setTitle change does not create a change...

Hope this outlines the issue better. Thanks.

I got it it. It was a bad connection with the .nib file.

Thanks.
