UIImageView 动画

---

1、播放图片集

    @property (nonatomic, strong) UIImageView *playImageView;

    self.playImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
    [self.view addSubview:self.playImageView];

    // 创建图片集
    NSMutableArray *imageArray = [NSMutableArray arrayWithCapacity:0];

    for (int i = 1; i < 30; i++) {
        // 添加图片
        [imageArray addObject:[UIImage imageNamed:[NSString stringWithFormat:@"%d.jpg", i]]];
    }

    // 播放图片集
    self.playImageView.animationImages = imageArray;    // 设置播放的图片集（需将图片添加到数组 imageArray 中）
    self.playImageView.animationDuration = 29;          // 设置播放整个图片集的时间
    self.playImageView.animationRepeatCount = 0;        // 设置循环播放次数，默认为 0 一直循环

    [self.playImageView startAnimating];                // 开始播放

    // [self.playImageView stopAnimating];              // 停止播放动画

• 2.1 库导入

  	#import <AudioToolbox/AudioToolbox.h>
  

• 2.2 创建

      @property (nonatomic, strong) UIImageView *playImageView;
  
      // 创建播放视图
      self.playImageView = [[UIImageView alloc] initWithFrame:self.view.bounds];
      self.playImageView.image = [UIImage imageNamed:@"background.jpg"];

      NSArray *buttonImageNameArray = @[@"fart.png", @"cymbal.png", @"drink.png", @"eat.png", @"pie.png", @"scratch.png"];
  
      for (int i = 0; i < 11; i++) {

- ## 2.4 播放动画
	``` Objective-C

- ## 2.5 播放声音
	``` Objective-C
