- (void)viewDidLoad {
[super viewDidLoad];
//UIImageView
//1.开辟空间并且初始化
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageWithContentsOfFile:@"/Users/lanou/Desktop/iOS-课堂学习/UI05_UIImageView、UIGestureRecognizer/UI05_UIImageView、UIGestureRecognizer/sea.png"]];
//2.设置 属性frame
imageView.frame = CGRectMake(50, 50, 300, 100);
//UIImageView 的用户交互默认是关闭的,需要我们打开
imageView.userInteractionEnabled = YES;//打开用户交互
//3.添加
[self.view addSubview:imageView];
//4.释放
[imageView release];

// 给UIImageView  添加图片序列数组
// 1. 创建imageView
UIImageView *imageView2 = [[UIImageView alloc] initWithFrame:(CGRectMake(80, 300, 200, 200))];

//2.设置
//(1)设置图片序列属性 animationImages
NSMutableArray *picArray = [NSMutableArray array];

for (int i = 1; i <= 22 ; i++) {
//图片名
NSString *imageName = [NSString stringWithFormat:@"Zombie%d.tiff", i];
//图片image
UIImage *image = [UIImage imageNamed:imageName];
//把图片对象添加到数组中
[picArray addObject:image];

}
//(2)给imageView 的动画图片序列赋值
imageView2.animationImages = picArray;
//(3)设置动画属性,持续时间,重复次数等
imageView2.animationDuration = 2;//2秒
imageView2.animationRepeatCount = 0;//设置为0,一直重复播放
//(4)开始动画
[imageView2 startAnimating];

//3.添加
[self.view addSubview:imageView2];
//4.释放
[imageView2 release];

//知识点三:手势识别器 UIGestureRecognizer
//(1)Tap
//1.创建手势识别器
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction:)];
//2.设置属性
tap.numberOfTapsRequired = 1;//单机,轻拍一次
tap.numberOfTouchesRequired = 1;//一个手指头
//3.把手势识别器添加到视图上
//    [imageView addGestureRecognizer:tap];
//4.释放
[tap release];

//(2)longPress
//1.创建
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressAction:)];
//2.设置
longPress.minimumPressDuration = 2;//需要长按时间2秒
//3.添加
//    [imageView addGestureRecognizer:longPress];
//4.释放
[longPress release];
//5.方法实现

//(3)pan平移手势
//1.创建
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panAction:)];
//2.设置
//3.添加
[imageView addGestureRecognizer:pan];
//4.释放
[pan release];
//5.方法实现,视图跟随手指移动

//(4)swipe 轻扫手势 离散手势 非持续性,没有changed状态
//1.创建
UISwipeGestureRecognizer *swipe = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeAction:)];
//2.设置
//注意:轻扫手势不需要设置轻扫方向,屏幕边缘轻扫需要设置轻扫方向
//3.添加
[imageView addGestureRecognizer:swipe];
//4.释放
[swipe  release];
//5.方法实现

//(5)screenEdgePan 屏幕边缘轻扫
UIScreenEdgePanGestureRecognizer *screenEdge = [[UIScreenEdgePanGestureRecognizer alloc] initWithTarget:self action:@selector(screenEdgeAction:)];
//设置边缘轻扫属性(设置边缘轻扫方向)
screenEdge.edges = UIRectEdgeRight;//左侧才会检测到
//添加
[self.view addGestureRecognizer:screenEdge];
[screenEdge release];

//(6)rotation 旋转
UIRotationGestureRecognizer *rotation = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotationAction:)];
[imageView addGestureRecognizer:rotation];
[rotation release];

//(7)pinch 捏合手势识别器
UIPinchGestureRecognizer *pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchAction:)];
[imageView addGestureRecognizer:pinch];
[pinch release];

// Do any additional setup after loading the view.

#pragma mark- pan(pan手势)
- (void)panAction:(UIPanGestureRecognizer *)pan{
//1.获取手势识别器所在的位置
UIView *imageView = pan.view;
//2.获取视图的变换点
CGPoint transPoint = [pan translationInView:imageView];
//3.改变视图的transform,对视图进行交换
//(1) 在每次进行的交换,都是基于视图的原始状态进行的变换 make开头的方法
//    imageView.transform = CGAffineTransformMakeTranslation(transPoint.x, transPoint.y);
//(2)基于上一次状态的进行的变换
imageView.transform = CGAffineTransformTranslate(imageView.transform, transPoint.x, transPoint.y);
