UIImageView動畫問題？

Question

我想使用CGAffineTransformScale製作UIImageView的動畫，並伴隨着動畫，uiimageview也應該改變它的原點。讓我寫下面的方法，

- （無效）imageDidMoving {

imageV = [[UIImageView alloc] init]; 
imageV.frame = CGRectMake(0, 0, 768, 1024); 
imageV.contentMode = UIViewContentModeScaleToFill; 
[self.view addSubview:imageV]; 
imageV.image = [UIImage imageNamed:@"image.png"]; 
imageV.autoresizingMask = UIViewAutoresizingFlexibleWidth || UIViewAutoresizingFlexibleHeight; 

imageV.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.1, 0.1); 
[UIView beginAnimations:@"image animation" context:nil]; 
[UIView setAnimationDuration: 0.75];  
imageV.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.0, 1.0); 
[UIView commitAnimations]; 

[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:.3]; 
imageV.transform = CGAffineTransformScale(CGAffineTransformIdentity,1.5, 1.5); 
[UIView commitAnimations]; 

}

，但它並沒有奏效。 我也使用CGAffineTransformScale代替，

CGRect frame2 = CGRectMake(70,70, 300, 600);    
    [UIView beginAnimations:nil context:nil]; 
    [UIView setAnimationDuration:1.0]; 
    imageView.frame = frame2; 
    [UIView commitAnimations]; 

，但它也不能正常工作？

如何在不使用NSTimer的情況下縮放和更改UIImageView的原點？

imageV.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.1, 0.1); 
[UIView beginAnimations:@"image animation" context:nil]; 
[UIView setAnimationDuration: 0.75];  
imageV.center = CGPointMake(65, 270); 
imageV.transform = CGAffineTransformScale(CGAffineTransformIdentity, 1.76, 1.24); 
[UIView commitAnimations];
