UIAnimation的理解

我正在尝试使用以下代码来执行一些动画

-(void) performSlidingfromX:(int) xx fromY:(int) yy 
{
UIImageView *Image= [self getImage];

[UIView beginAnimations:nil context:NULL];  
[UIView setAnimationDuration: 1.0];
[UIView setAnimationBeginsFromCurrentState:true];
[UIView setAnimationCurve: UIViewAnimationCurveEaseOut];
[token setFrame:CGRectMake(xx, yy, 64, 64)];
[UIView commitAnimations];

}

我在 for 循环中像这样调用

for (i = 0; i < totMoves; i++) {
    Moment *m = [moments objectAtIndex:i];
    int xx= [m X];
    int yy= [m Y];

    [self performSlidingfromX:xx fromY:yy];

}

我面临的问题是它的动画到最终位置，例如，如果我输入 xx,yy 的以下时刻

0,0
50,0
50,50

它将图像对角线从 0,0 移动到 50,50，我希望它先水平滑动，然后垂直滑动。

有帮助吗？

Thanks

使用新的块动画。它简单且稳定：

[UIView animateWithDuration:0.5 
                          delay:0 
                        options:UIViewAnimationOptionBeginFromCurrentState
                     animations:^{
                         [token setFrame:CGRectMake(xx, 0, 64, 64)];
                         //here you may add any othe actions, but notice, that ALL of them will do in SINGLE step. so, we setting ONLY xx coordinate to move it horizantly first.
                     } 
                     completion:^(BOOL finished){

                         //here any actions, thet must be done AFTER 1st animation is finished. If you whant to loop animations, call your function here.
                         [UIView animateWithDuration:0.5 
                                               delay:0 
                                             options:UIViewAnimationOptionBeginFromCurrentState 
                                          animations:^{[token setFrame:CGRectMake(xx, yy, 64, 64)];} // adding yy coordinate to move it verticaly} 
                                          completion:nil];
                     }];
