Help! iOS

I am writing an app but am stuck.

if (Ball.center.y < 307) { [self PlacePlatform]; }

PlacePlatform makes the platform in the game regenerate in a random place across the x axis. But as the ball falls and gets past 307 on the y axis, the platform keeps on regenerating over and over again as the code tells it. I only want this to happen once? Help will be very much appreciated as i am only new to iOS.

Sure. Shoot me a dropbox link or something.

Without seeing the rest of your code, this is likely happening because the ball continues to be beneath the y threshold for every run of the game loop.

A quickie solution would be to set a class variable to track if the platform has been created. Up in the class implementation add something like BOOL _platformLoaded = NO

Then 

if (Ball.center.y < 307) { 
   [self PlacePlatform]; 
   _platformLoaded = YES;
}

Then elsewhere you test if the y point is greater than or equal to 307 and reset the _platformLoaded = NO. Perhaps in the else clause?

Again, this is just shooting from the hip without looking at your code.
