Default Help with ViewDidLoad..

Hi

I am trying to run an action 10 seconds after the screen appears. At the moment I have this

Quote:
- (void)viewDidLoad
{

[super viewDidLoad];

(sleep(5));

levelSix *modal = [[levelSix alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:modal animated:NO];


}
However this is being called before the view actually appears on the screen (At the end of the screen before)

I hope somebody could spare a minute or two to help me out.


Thanks a lot

Of course it does. That's why you have viewWillAppear and viewDidAppear

I've tried both of these, and the same thing happened.

It's waiting 5 seconds BEFORE the screen loads on all;

ViewDidLoad
ViewDidAppear
and
ViewWillAppear

Any other ideas?

I just saw your code... sleep()? No, no, no. No. Use an NSTimer and in viewDidAppear method.

As Baja says, sleep is really bad news in Cocoa. It causes the whole app to freeze up.

use code like this:

Code:
- (void) showMyView;
{
//create and install the view that you want to show up after a delay
}

- (void) viewDidAppear
{
   [self performSelector: @selector(showMyView) 
     withObject: nil 
     afterDelay: 5.0];
}
The method peformSelector:withObject:afterDelay: sets up a method to be called after a delay. In this case, it will call a second method, showMyView. Move your code that creates and installs the view into that method.
