iphone火焰演示了动画效果，31天工程中的第二天。-For day 2 I picked something that has been popular in the App Store? 揂nimations?.　The first App I did was iFlame which was a simple video of a flame I shot myself.　At the time I had not seen a flame or lighter in the App Store and thought it would be cool to have a flame to hold up at a concert.　My first challenge was getting my flame video to repeat without a pause.　 Then, I soon saw Crazy Lighter and wondered how they got it working with an infinite loop.　I cannot say this is 搕he? way that Crazy Lighter works but this will do for us.　Instead of using a video you can use a UIImageView with a sequence of images and just loop them.　The key section of code is below.



　　　 // create the view that will execute our animation

　　 UIImageView* campFireView = [[UIImageView alloc] initWithFrame:self.view.frame]

　　

　　 // load all the frames of our animation

　　 campFireView.animationImages = [NSArray arrayWithObjects:　

　　　　　　　　　　　　　　　　 [UIImage imageName
