Hi, I need a little help, maybe you can help me.

How I can randomize two images?, I just want to display one, but random.

I hope I can help.

Thanks.

Sorry for my bad English

@ulbricho Use arc4random(), and get a random number between 0 and 1, and use image one if it is 0, or image 2 if it is 1.

@TheEagle1100 thanks for the response.i actually paused like crazy to get the code down.Would of been easier if you had xcode in full screen haha...And i figured out the missing code thats cut off the screen.But yeah you should do more xcode tut,maybe something like adding a timer to count down than after it reaches 0 it will go to the next scene..

@johnydee187 Yeah, I'll probably do some more tutorials at some point, but I'm really busy with school right now.
