iphone - 移动UIImageView

Question

第一个动画结束后,我很难将图像移动到另一个位置.

图像在我指定的点处动画,然后停止(工作正常).然后我想将图像移动到另一个位置并重复.

这是我的代码:

-(void) loadTap {

NSArray *imageArray  = [[NSArray alloc] initWithObjects:
                                                        [UIImage imageNamed:@"tap1.png"],
                                                        [UIImage imageNamed:@"tap2.png"],
                                                        [UIImage imageNamed:@"tap3.png"],
                                                        [UIImage imageNamed:@"tap4.png"],                                                       
                                                nil];

    tapImage.animationImages = imageArray;
    tapImage.animationRepeatCount = 1;

    [imageArray release];

    tapImage.animationDuration = 1;
    tapImage.animationRepeatCount = 20;

    [tapImage startAnimating];
    tapImage.center = CGPointMake(156, 110);

}

谢谢你的帮助.

为了移动图像,您应该将代码包含在动画块中移动:

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
tapImage.center = CGPointMake(156, 110);
[UIView commitAnimations];

您还可以使用方法在完成动画时执行一个UIView setAnimationDidStopSelector:方法.

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:@selector(animateImages)];
tapImage.center = CGPointMake(156, 110);
[UIView commitAnimations];

//other stuff

-(void)animateImages{
     [tapImage startAnimating];
}
