Question

In my application I use performSelector to call methods. I have three different methods in my application, I want that randomly I assign one of these three methods to perform selector. Here is my code.

[self performSelector:@selector()];

Here is my three methods..

-(void)Act1
{
}

-(void)Act2
{
}

-(void)Act3
{
}

Now I want to assign each time one method randomly to selector. Can any one guide me how I can do this.

This should do it:

int rand = (arc4random() % 3) + 1;
[self performSelector:NSSelectorFromString([NSString stringWithFormat:@"Act%d",rand])];
