UIImage view animation problem
<p>I have done the effect of playing lots of images like below:</p>

<pre><code>NSInteger faceNum = 12;

NSMutableArray *faceArray = [[NSMutableArray alloc] initWithCapacity:faceNum];

for (int i = 1;i&lt;faceNum+1; i++) {
    NSString *facename = [[NSBundle mainBundle] 
      pathForResource:[NSString   stringWithFormat:@"animationFace%d",i] ofType:@"png"];    
    UIImage *faceImage = [UIImage imageWithContentsOfFile:facename];    
    [faceArray addObject:faceImage];
}

 UIImageView *faceView = [[UIImageView alloc] 
   initWithFrame:CGRectMake(414, 157, 161, 124)];

 faceView.animationImages = faceArray;    
 faceView.animationDuration = 30;    
 faceView.animationRepeatCount = 0;

 [faceView startAnimating];    
 [self.view addSubview:faceView];    
 [faceView release];    
 [faceArray release];
</code></pre>

<p>And how to add the EaseInEaseOut effect to this.One picture disappear gradually，then another picture appear gradually.
Thanks</p>
