本文详细介绍了如何使用UIView的beginAnimations和commitAnimations方法实现视图的动画位移效果，包括设置动画参数、过渡类型和回调方法。通过实例演示了不同动画效果的应用，适合iOS开发人员学习。

   [UIView beginAnimations:@"suck" context:NULL];
    [UIView setAnimationDuration:0.6];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationPosition:[self convertPoint:CGPointMake(self.closeX, self.closeY) toView:[self superview]]];
    [UIView setAnimationTransition:103 forView:self cache:NO];//103  就是suckEffect  的枚举
    [UIView setAnimationDidStopSelector:@selector(removeFromSuperview)];
    [UIView commitAnimations];

编译的时候出现'UIView' may not respond to '+setAnimationPosition:' 不用理会，其实setAnimationPosition 是起作用的。

    [UIView beginAnimations:@"suckEffect" context:NULL];
    [UIView setAnimationTransition:103 forView:view1 cache:YES];//forview后面是要改变的view
    [UIView setAnimationDuration:3];
    [UIView setAnimationPosition:CGPointMake(400, 200)];// 你要的位置！
    [UIView commitAnimations];

    CATransition *transition = [CATransition animation];
    transition.duration = 1.5f;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
   transition.type = kCATransitionReveal;
    transition.subtype = kCATransitionFromTop;
    [UIView setAnimationPosition:CGPointMake(400, 200)];
    transition.removedOnCompletion = TRUE;
    [[view1 layer] addAnimation:transition forKey:nil];
