Question

This is what I want to do:
I want a timer, to fire a method and then, in the end of this method, be toggled off, and turn on an other timer on another method, and then entering a loop.

So what are the codes used to toggle between on and off the timer on a method?

In Delphi I use:

timer.enable:=True; // timer.enable:=False;

Are there a similar way to do it on objective-c?
I’m using Xcode 4.4
Thanks!

To turn the timer off, call invalidate on your timer like so:

[yourTimer invalidate]

And then to start a new one:

NSTimer *newTimer;

                     newTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 //Every how many seconds
                                                                target:self
                                                              selector:@selector(methodToCall)
                                                              userInfo:nil
                                                               repeats:YES];
