OC-UIImage动画&UIImageView动画&UIView动画NSTimer动画

1.UIKit 层面的动画

预备：动画 — 帧动画

1.1UIImage

1.2UIImageView

预备：动画 — 补间动画

1.3UIView

系统为UIView提供的专门用于控制视图实现动画的方法，这些方式以类方法出现的，方法名开头为animate….

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {//    [UIView animateWithDuration:2 animations:^{//        //设置动画的最终状态//        self.imageView.alpha = 1;//        CGPoint center = self.imageView.center;//        center.y += 300;//        self.imageView.center = center;//    }];//    [UIView animateWithDuration:2 animations:^{//        self.imageView.alpha = 1;//    } completion:^(BOOL finished) {//        //动画执行完 执行 该代码块//        NSLog(@"动画执行完");//    }];    /*     Duration 动画持续时间     delay  等待时间     options 动画选项  （动画匀速 变速 重复）     animations 动画结束后什么样子 （最终状态）     completion 动画结束后做什么    */     [UIView animateWithDuration:2 delay:3 options:UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse animations:^{         CGPoint center = self.imageView.center;         center.y += 300;         self.imageView.center = center;     } completion:nil];}- (void)viewDidLoad {    [super viewDidLoad];    //设置 动画的初始状态//    self.imageView.alpha = 0;}

转场动画：

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {    self.imageIndex++;    if (self.imageIndex > 43) return;    NSString *imageName = [NSString stringWithFormat:@"a%ld",self.imageIndex];    //添加转场动画    [UIView transitionWithView:self.imageView duration:1 options:UIViewAnimationOptionTransitionCurlUp animations:^{        self.imageView.image = [UIImage imageNamed:imageName];    } completion:nil];}

- (void)viewDidLoad {    [super viewDidLoad];    //ship-anim 图片名称 但是索引0 不要    //duration 动画持续时间    UIImage *image = [UIImage animatedImageNamed:@"ship-anim" duration:1];    self.imageView.image = image;    [self runAnimationWithImageView:self.npcImageView imageFileName:@"yinJiaoDaWang" imageCount:32 speed:1/20.0];//    [self runAnimationWithImageView:self.npcImageView2 imageFileName:@"shaoNv3_" imageCount:40 speed:1/15.0];  /******** UIImageView动画 *********************************/    NSMutableArray *allImages = [NSMutableArray array];    for (NSInteger i = 0; i < 32; i++) {        //拼接图片的名称        NSString *fileName = [NSString stringWithFormat:@"yinJiaoDaWang%02ld",i+1];        //创建图片对象        UIImage *image = [UIImage imageNamed:fileName];        //将创建好的图片 添加到数组中        [allImages addObject:image];    }    //设置 动画所需图片 （需要的是一个图片数组）    self.npcImageView.animationImages = allImages;    //设置动画的时长  （一次多长时间）    self.npcImageView.animationDuration = 1 / 10.0 * 32;    //设置动画运行次数   值为0 是无限运行    self.npcImageView.animationRepeatCount = 0;    //运行动画    [self.npcImageView startAnimating];    if (self.npcImageView.animationRepeatCount != 0) {        //动画运行完 要释放动画数组        //获取动画总时间        CGFloat afterDelay = self.npcImageView.animationDuration * self.npcImageView.animationRepeatCount;        //等待 afterDelay 时间后 向 self.npcImageView 发送setAnimationImages 消息 并把 nil 做为参数传给 setAnimationImages 方法        [self.npcImageView performSelector:@selector(setAnimationImages:) withObject:nil afterDelay:afterDelay];    }}

页面跳转动画：

MyViewController *myVC = [[MyViewController alloc]init];    /*    UIModalTransitionStyleCoverVertical    UIModalTransitionStyleFlipHorizontal    UIModalTransitionStyleCrossDissolve    UIModalTransitionStylePartialCurl     */    //设置跳转动画的类型    myVC.modalTransitionStyle = UIModalTransitionStylePartialCurl;    [self presentViewController:myVC animated:YES completion:nil];

2.NSTimer动画

• 创建定时器
  
  • [NSTimer schedulexxx];
  • [NSTimer timerWithxxx];
• 销毁定时器
  
  • [timer invalidate];

动画主要修改frame bounds center alpha等属性

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {    [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(timer:) userInfo:nil repeats:YES];}- (void)viewDidLoad {    [super viewDidLoad];//    self.imageView.alpha = 0;}-(void)timer:(NSTimer *)sender {    CGRect bounds = self.imageView.bounds;    bounds.size.width +=5;    bounds.size.height += 5;    self.imageView.bounds = bounds;//    CGRect frame = self.imageView.frame;//    frame.size.width +=5;//    frame.size.height += 5;//    self.imageView.frame = frame;//    CGPoint center = self.imageView.center;//    center.y += 5;//    self.imageView.center = center;//    self.imageView.alpha += 0.1;//    if (self.imageView.alpha >= 1) {//        [sender invalidate]; //销毁定时器//    }    NSLog(@"-------");}
