Question

-(ibaction)sometouched:(id)sender
{
    [UIView beginAnimations:@"first one" context:nil];
    [UIView setAnimationDuration:1.0];
    [myview setFrame:CGRectMake(0,y,width.height.);
    [UIView commitAnimations];

    [UIView beginAnimations:@"second one" context:nil];
    [UIView setAnimationDuration:1.0];
    [myview setFrame:CGRectMake(x,0,width.height.);
    [UIView commitAnimations];
}

这只是一个证明。我想要的是动画需要2个部分。第一个向下移动视图，第二个向右移动视图。但我得到的是它迅速向下移动然后向右移动。

我在这里想念的是什么？

您需要从animationDidStop委托方法开始第二个动画。

-(ibaction)sometouched:(id)sender
{
    [UIView beginAnimations:@"first one" context:nil];
    [UIView setAnimationDuration:1.0];
    [myview setFrame:CGRectMake(0,y,width.height.);
    [UIView setAnimationDelegate:self];
    [UIView commitAnimations];
}

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag {
    [UIView beginAnimations:@"second one" context:nil];
    [UIView setAnimationDuration:1.0];
    [myview setFrame:CGRectMake(x,0,width.height.);
    [UIView setAnimationDelegate:nil];
    [UIView commitAnimations];
}

如何连续执行多个动画？
