Randomizing

[wardyfloyd]

I have a button that randomizes its position when I load the app, but I need it to randomize every time I click it. right now I use this code as the x and y coordinates, and it works fine for randomizing when i first open the app.

int x1 = arc4random() % 230;
int y1 = arc4random() % 426;

also, this is the code for a timer i have for the button to pop up again.

-(void)buttonPressed1UIButton*)button {

[button setHidden:YES];
[NSTimer scheduledTimerWithTimeInterval:2
target:self selector:@selector(showButton1
userInfo:[NSDictionary dictionaryWithObjectsAndKeys:button, @"button", nil]
repeats:NO];

}

- (void)showButton1NSTimer*)timer {
[[[timer userInfo] objectForKey:@"button"] setHidden:NO];

}

How can I make the button randomize?

UIButton inherits from UIView, which means it has a "center" property. So you can just set that.

button.center = CGPointMake( arc4random() % 230, arc4random() % 426 );

No, you misunderstood my problem. When I open my app, the buttons are in a random position, but I need them to randomize every time i click the specific buttons, not just when the application opens.

Have you tried using smasher's suggestion in your buttonPressed1: method?

Thanks, I'm new to objective c. this is a real help. while we are on this subject, if i wanted a button to be hidden when i clicked it, but i wanted it to start hidden for a certain amount of time, how would i do that?

There should be a viewDidLoad method for your view controller. You may want to set the initial setting along with a timer there. I hope this is what you were asking for.

Good luck!

edit: Alternatively, you might have to place the code in your appDelegate's applicationDidFinishLaunching method... you'll find out.
