我不知道如何制作动画,也不知道如何将其放入 Xcode。有人可以给我一些背景信息吗?

NSArray *animationArray = [NSArray arrayWithObjects:[UIImage imageNamed@"firstImage",[UIImage imageNamed@"secondImage",nil];  //add as many as you want

现在您需要一个 imageview 来将动画设置为:

self.myImageView.animationImages =animationArray;
self.myImageView.animationDuration = 3;
self.myImageView.animationRepeatCount = -1; //keeps going infinitely

[self.myImageView startAnimating];

我猜你想要做的是创建一个动画图像,而不是动画视图转换......这里是关于为 iOS 创建动画的两种方法的一些背景知识。

第一个选项:创建一个图像数组(UIImage),然后使用 startAnimating 方法。像这样的东西:

imageView.image = yourLastImage;  
// Do this first so that after the animation is complete the image view till show your last image.

NSArray * imageArray  = [[NSArray alloc] initWithObjects:
[UIImage imageNamed:@"image1.png"],  
[UIImage imageNamed:@"image2.png"],
[UIImage imageNamed:@"image3.png"],                         
[UIImage imageNamed:@"image4.png"],
nil]; 

// Note: here you may instead want to use something like [UIImage imageWithContentsOfFile:[self localImagePath:NO]] instead depending upon your targeted iOS version.



UIImageView * animatedImageView = [[UIImageView alloc] initWithFrame:
        CGRectMake(100, 125, 150, 130)];
    animatedImageView.animationImages = imageArray;
    animatedImageView.animationDuration = 1.1;
        myAnimation.animationRepeatCount = 1;
    animatedImageView.contentMode = UIViewContentModeBottomLeft;

    [self.view addSubview:animatedImageView];
    [animatedImageView startAnimating];

第二个选项:(适用于 iOS 4 及更高版本)您可以使用基于块的方法。这是 StackOverflow 上的参考文章的链接。

iPhone OS 4.0 中有哪些基于块的动画方法?

此外,您可能想查看 Apple 提供的与 Core Animation 相关的文档:
