Ios 循环图像的动画不显示

我从网上下载了动画篝火。我的图像序列是“*.png”，无法正常工作。它一直循环到最后。它不显示图像。为什么我不能为这段代码设置动画？我做错了什么

        UIImageView* campFireView = [[UIImageView alloc] initWithFrame:screenx.frame];
        int j;
        int i;

        for (j = 1, i = 0; i < 28; i =1)
        {
            NSLog( @"%i.png", i);
            campFireView.animationImages = [NSArray arrayWithObjects:
                                            [UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]], nil];
        }
        // all frames will execute in 1.75 seconds
        campFireView.animationDuration = .15;
        // repeat the annimation forever
        campFireView.animationRepeatCount = 1;
        // start animatinganimationRepeatCount:1];

        [campFireView startAnimating];

        // add the animation view to the main window 
        [self.view addSubview:campFireView]; 
        [campFireView release]; 

UIImageView*campFireView=[[UIImageView alloc]initWithFrame:screenx.frame]；
int j；
int i；
对于（j=1，i=0；i<28；i=1）
{
NSLog（@“%i.png”，i）；
campFireView.animationImages=[NSArray arrayWithObjects:
[UIImage ImageName:[NSString stringWithFormat:@“%i.png”，i]]，nil]；
}
//所有帧将在1.75秒内执行
campFireView.animationDuration=.15；
//永远重复这个纪念日
campFireView.animationRepeatCount=1；
//开始动画AnimationRepeatCount:1]；
[campFireView startAnimating]；
//将动画视图添加到主窗口
[self.view addSubview:campFireView]；
[campFireView发布]；

每次打电话时：

        UIImageView* campFireView = [[UIImageView alloc] initWithFrame:screenx.frame];
        int j;
        int i;

        for (j = 1, i = 0; i < 28; i =1)
        {
            NSLog( @"%i.png", i);
            campFireView.animationImages = [NSArray arrayWithObjects:
                                            [UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]], nil];
        }
        // all frames will execute in 1.75 seconds
        campFireView.animationDuration = .15;
        // repeat the annimation forever
        campFireView.animationRepeatCount = 1;
        // start animatinganimationRepeatCount:1];

        [campFireView startAnimating];

        // add the animation view to the main window 
        [self.view addSubview:campFireView]; 
        [campFireView release]; 

        campFireView.animationImages = [NSArray arrayWithObjects:
                                        [UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]], nil];

您正在将

animationImages

设置为一项数组。您可能想做的是：

        UIImageView* campFireView = [[UIImageView alloc] initWithFrame:screenx.frame];
        int j;
        int i;

        for (j = 1, i = 0; i < 28; i =1)
        {
            NSLog( @"%i.png", i);
            campFireView.animationImages = [NSArray arrayWithObjects:
                                            [UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]], nil];
        }
        // all frames will execute in 1.75 seconds
        campFireView.animationDuration = .15;
        // repeat the annimation forever
        campFireView.animationRepeatCount = 1;
        // start animatinganimationRepeatCount:1];

        [campFireView startAnimating];

        // add the animation view to the main window 
        [self.view addSubview:campFireView]; 
        [campFireView release]; 

    NSMutableArray *animationImages = [NSMutableArray array];

    for (i = 0; i < 28; i++)
    {
        [animationImages addObject:[UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]]];
    }

    campfireView.animationImages = animationImages;

NSMutableArray*animationImages=[NSMutableArray]；
对于（i=0；i<28；i++）
{
[animationImages添加对象：[UIImage ImageName:[NSString stringWithFormat:@“%i.png”，i]]；
}
campfireView.animationImages=animationImages；

另外-我不知道你的

for

循环发生了什么，但我修复了它。

当你循环时，然后每次为animationImages提供一个图像

        UIImageView* campFireView = [[UIImageView alloc] initWithFrame:screenx.frame];
        int j;
        int i;

        for (j = 1, i = 0; i < 28; i =1)
        {
            NSLog( @"%i.png", i);
            campFireView.animationImages = [NSArray arrayWithObjects:
                                            [UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]], nil];
        }
        // all frames will execute in 1.75 seconds
        campFireView.animationDuration = .15;
        // repeat the annimation forever
        campFireView.animationRepeatCount = 1;
        // start animatinganimationRepeatCount:1];

        [campFireView startAnimating];

        // add the animation view to the main window 
        [self.view addSubview:campFireView]; 
        [campFireView release]; 

NSMutableArray *arrImgs = [NSMutableArray array];

for (i = 0; i < 28; i++)
    {
        [arrImgs addObject:[UIImage imageNamed:[NSString stringWithFormat:@"%i.png",i]]];
    }

campfireView.animationImages  = [NSArray arrayWithArray:arrImgs];

NSMutableArray*arrImgs=[NSMutableArray]；
对于（i=0；i<28；i++）
{
[arrImgs addObject:[UIImage ImageName:[NSString stringWithFormat:@“%i.png”，i]]；
}
campfireView.animationImages=[NSArray arrayWithArray:arrImgs]；

[animationImages添加对象：[UIImage ImageName:[NSString stringWithFormat:@“%i.png”，i]]；代码在XCODE 4上显示为SIGABRT。5@user1692698嗯，你的

循环被破坏得很厉害，所以无论如何只执行了一次，所以更正了我的答案。

imageNamed

是否为

i

的某个值返回一个nil图像？@user1692698是否解决了这个问题？为什么不使用

%d.png

格式化程序而不是

%i.png

？在

循环的

标题中，变量
i
和
j
的奇怪组合是什么？
