iphone sdk：如何在UIImageView中使用CoreAnimation動畫設置圖像集？

Question

我已經在UIImageView中加載了一組圖像。如何使用CoreAnimation在UIImageView中對圖像進行動畫處理？ PLZ給我suggesstions

Answer 1

如果你只想動畫在ImageView的圖像集，下面的代碼將有助於

UIImageView* animatedImageView = [[UIImageView alloc]init]; 
animatedImageView.animationImages = [NSArray arrayWithObjects:  
            [UIImage imageNamed:@"1.gif"], 
            [UIImage imageNamed:@"2.gif"], 
            [UIImage imageNamed:@"3.gif"], 
            [UIImage imageNamed:@"4.gif"], nil]; 
animatedImageView.animationDuration = 1.0f; 
animatedImageView.animationRepeatCount = 0; 
[animatedImageView startAnimating]; 
[self.view addSubview: animatedImageView]; 

Answer 2

它是與剩餘時間的動畫圖像非常漂亮的代碼，如果你設置的計時器報警在動畫根據定時器的剩餘秒我已經使用圖像以便使花

{圖像

// -----------------圖片動畫------------------- //

-(void)imageAnimationMethod 

    { 

imageAnimation=[[UIImageView alloc]initWithFrame:CGRectMake(20, 150, 135, 135)]; 


    [ self.view addSubview:imageAnimation]; 

imageAnimation.animationImages=[NSArray arrayWithObjects: 
           [UIImage imageNamed:@"101.png"], 
           [UIImage imageNamed:@"102.png"], 
           [UIImage imageNamed:@"103.png"], 
           [UIImage imageNamed:@"104.png"], 
           [UIImage imageNamed:@"105.png"], 
           [UIImage imageNamed:@"106.png"], 
           [UIImage imageNamed:@"107.png"], 
           [UIImage imageNamed:@"108.png"], 
           [UIImage imageNamed:@"109.png"], 
           [UIImage imageNamed:@"110.png"], 
           [UIImage imageNamed:@"111.png"], 
           [UIImage imageNamed:@"112.png"], 
           [UIImage imageNamed:@"113.png"], 
           [UIImage imageNamed:@"114.png"], 
           [UIImage imageNamed:@"115.png"], 
           [UIImage imageNamed:@"116.png"], 

          nil]; 

// -----剩餘的第二剩餘的計時器--------- //

int i=remaining*16/16; 


    imageAnimation.animationDuration=i; 

    imageAnimation.animationRepeatCount=0;
