问题描述

我是新来的iOS开发动画。如何动画一个图像按钮，四个或五个按钮中的iOS顶部？每当点击任一按钮时，图像按钮被放置在该按钮的顶部。

I am new to animation in iOS development. How to animate the one image button to the top of four or five buttons in iOS? Whenever I tap any of the buttons, the image button has to be placed at the top of that button.

推荐答案

在.h文件中，声明的ImageButton为：

In .h file,declare the imageButton as:

    int selectedCurveIndex;
    @property(nonatomic,retain)IBOutlet UIButton *mvngButton;
   -(IBAction) btnMoveTo:(id)sender;
-(IBAction) btnDownUnder:(id)sender;

在.m文件，

static int curveValues [] = {
UIViewAnimationOptionCurveEaseInOut,
UIViewAnimationOptionCurveEaseIn,
UIViewAnimationOptionCurveEaseOut,
UIViewAnimationOptionCurveLinear};

   -(IBAction) btnMoveTo:(id)sender
{
UIButton *btn=(UIButton *)sender;
[mvngButton moveTo: CGPointMake(btn.center.x - (mvngButton.frame.size.width/2),btn.frame.origin.y - (mvngButton.frame.size.height + 5.0))duration:2.0 option:curveValues[selectedCurveIndex]];
}
-(IBAction) btnDownUnder:(id)sender
{
UIButton *btn=(UIButton *)sender;
[btn downUnder:1.0 option:curveValues[selectedCurveIndex]];
}

对于剩下的四个按钮，在厦门国际银行文件， touchupinside 与 - （IBAction为）btnMoveTo：（ID）发送方法。
而对于在厦门国际银行文件的ImageButton，里面润色方法与 - （IBAction为）btnDownUnder：（ID）发送方法和引用插座与 mvngButton 。

For the remaining four buttons,in xib file,touchupinside with the -(IBAction) btnMoveTo:(id)sender method. And for the imageButton in xib file,touch up inside method with the -(IBAction) btnDownUnder:(id)sender method and the referencing outlet with the mvngButton.
