Day Two Bonfire

今天试试运用 UIImageView 来制作一个"营火动画"

首先运行以安装好的xCode,和第一天一样

选择: File->New Project.

从 "New Project" 窗口

选择: iPhone OS ->Applications-> View-Based Application
命名:我这里命名为"Bonfire"

(1)在xcode打开BonfireViewController.m文件

在-(void)viewDidLoad{ }里面添加代码，如下

-(void)viewDidLoad{

// 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 imageNamed:@"campFire01.gif"],
                                [UIImage imageNamed:@"campFire02.gif"],
                                [UIImage imageNamed:@"campFire03.gif"],
                                [UIImage imageNamed:@"campFire04.gif"],
                                [UIImage imageNamed:@"campFire05.gif"],
                                [UIImage imageNamed:@"campFire06.gif"],
                                [UIImage imageNamed:@"campFire07.gif"],
                                [UIImage imageNamed:@"campFire08.gif"],
                                [UIImage imageNamed:@"campFire09.gif"],
                                [UIImage imageNamed:@"campFire10.gif"],
                                [UIImage imageNamed:@"campFire11.gif"],
                                [UIImage imageNamed:@"campFire12.gif"],
                                [UIImage imageNamed:@"campFire13.gif"],
                                [UIImage imageNamed:@"campFire14.gif"],
                                [UIImage imageNamed:@"campFire15.gif"],
                                [UIImage imageNamed:@"campFire16.gif"],
                                [UIImage imageNamed:@"campFire17.gif"], nil];

    // all frames will execute in 1.75 seconds
    campFireView.animationDuration = 1.75;
    // repeat the annimation forever
    campFireView.animationRepeatCount = 0;
    // start animating
    [campFireView startAnimating];
    // add the animation view to the main window
    [self.view addSubview:campFireView];
}

(2)下载图片文件images.zip
把下载好的文件解压储存在与程序同一文件夹里

在xcode - Group & Files -在文件夹 Resource 上按鼠标右键Add->Existing files选择下载好的Defult.png图片;
同上在文件夹Resource上按鼠标右键 Add-> New Group, 命名为images;
在文件夹images 上按鼠标右键 Add->Existing files 选择下载好的在images里的所有图片。

最后在xCode选择 Build->Build and Go， save all 保存所有文件
