トム猫が牛乳を飲む(タイマー、フレームアニメーション)

1、タイマーを使ってトム猫が牛乳を飲むコードを実現する:

@interface ZMSecondViewController ()

@end

@implementation ZMSecondViewController

//                        ，self.view
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    //      
    catView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
    catView.image=[UIImage imageNamed:@"drink_0.jpg"];
    [self.view addSubview:catView];
    
    //    Button
    drinkButton=[UIButton buttonWithType:UIButtonTypeSystem];
    drinkButton.frame=CGRectMake(240, 290, 60, 60);
    [drinkButton addTarget:self action:@selector(drinkClick) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:drinkButton];
    
    //milk  
    //                 ，   （0，0）；
    milkView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 60, 60)];
    milkView.image=[UIImage imageNamed:@"milk.png"];
    [drinkButton addSubview:milkView];
    
    //      
    UIButton *goToFirstButton=[UIButton buttonWithType:UIButtonTypeSystem];
    goToFirstButton.frame=CGRectMake(5, 420, 60, 40);
    [goToFirstButton setTitle:@"Back" forState:UIControlStateNormal];
    [goToFirstButton addTarget:self action:@selector(goBackClick) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:goToFirstButton];
    
}

//       
- (void)drinkClick
{
    //           button ，     tom     ，      ，     ；   ，     ；
    //timer   ，       timer ，tom     
    if(_timer==nil)
    {
        _timer=[NSTimer scheduledTimerWithTimeInterval:0.12 target:self selector:@selector(drink) userInfo:nil repeats:YES];
        //     fire    ，       ，    ，  0.15     changePic  ；
        //    fire     ，       ，     changePic  ，  ，  ，  0.15     changePic   ；
        [_timer fire];
        //        ,   NSRunLoop   
        //          ，                
        [[NSRunLoop currentRunLoop] addTimer:_timer forMode:NSRunLoopCommonModes];
    }
}

//     ，        
- (void)drink
{
    _count++;
    NSString *picture=[NSString stringWithFormat:@"drink_%d.jpg",_count];
    catView.image=[UIImage imageNamed:picture];
    if(_count==80)
    {
        //_conut  0 ；        button  ，tom       
        _count=0;
        //          ；    tom          ,_timer        ；        ，   
        if(_timer!=nil)
        {
         //    timer,       ,timer    ，   
         //      ，             
        [_timer invalidate];
        //   ，        button   ，      ，       timer， tom     
        _timer =nil;
        }
    }
}

2、フレームアニメーション実現コード:

@interface ZMSecondViewController ()

@end

@implementation ZMSecondViewController
{
    int             i;
    UIImageView     *catView;
    NSMutableArray  *pictureArray;
}
//                        ，self.view
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    //      
    catView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 480)];
    catView.image=[UIImage imageNamed:@"drink_0.jpg"];
    [self.view addSubview:catView];
    
    //    Button
    UIButton *drinkButton=[UIButton buttonWithType:UIButtonTypeSystem];
    drinkButton.frame=CGRectMake(240, 290, 60, 60);
    [drinkButton addTarget:self action:@selector(drinkClick) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:drinkButton];
    
    //milk  
    //                 ，   （0，0）；
    UIImageView *milkView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 60, 60)];
    milkView.image=[UIImage imageNamed:@"milk.png"];
    [drinkButton addSubview:milkView];
    
    //            
    pictureArray=[[NSMutableArray alloc] init];
    for(i=1;i<81;i++)
    {
        NSString *imageName=[NSString stringWithFormat:@"drink_%d.jpg",i];
        UIImage *imageDrink=[UIImage imageNamed:imageName];
        [pictureArray addObject:imageDrink];
    }
 
    //      
    UIButton *goToFirstButton=[UIButton buttonWithType:UIButtonTypeSystem];
    goToFirstButton.frame=CGRectMake(5, 420, 60, 40);
    [goToFirstButton setTitle:@"Back" forState:UIControlStateNormal];
    [goToFirstButton addTarget:self action:@selector(goBackClick) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:goToFirstButton];
    
}

//       
- (void)drinkClick
{
    NSLog(@"   ");
    if(i==80)
    {
        //      ；     ，       _fireView       
        // Timer    ，Timer           ，                
        [catView stopAnimating];
        i=0;
    }
    else
    {
        //              ；          * 1/30.0 ;
        catView.animationDuration=8;
        
        //         ；      UIImage   
        catView.animationImages=pictureArray;
        
        //         ，    0，     
        catView.animationRepeatCount=1;
        
        //    
        [catView startAnimating];
    }
}

@end
