iOS中制作微信摇一摇的图框雏形

模拟一下微信摇一摇的时候，两个图片上下滑动开，中间露出一朵小花的操作。

在这里用到的是触摸事件

对应的方法提示为：

<p style="margin-top: 0px; margin-bottom: 0px; font-size: 18px; line-height: normal; font-family: Menlo;"><span style="font-variant-ligatures: no-common-ligatures">- (</span><span style="font-variant-ligatures: no-common-ligatures; color: #c32275">void</span><span style="font-variant-ligatures: no-common-ligatures">)motionBegan:(</span><span style="font-variant-ligatures: no-common-ligatures; color: #703daa">UIEventSubtype</span><span style="font-variant-ligatures: no-common-ligatures">)motion withEvent:(</span><span style="font-variant-ligatures: no-common-ligatures; color: #6122ae">UIEvent</span><span style="font-variant-ligatures: no-common-ligatures"> *)event</span></p>

动画的方法：

<p style="margin-top: 0px; margin-bottom: 0px; font-size: 18px; line-height: normal; font-family: Menlo; color: rgb(95, 49, 193);"><span style="font-variant-ligatures: no-common-ligatures; color: #6122ae">[UIView</span><span style="font-variant-ligatures: no-common-ligatures; color: #000000"> </span><span style="font-variant-ligatures: no-common-ligatures">animateWithDuration</span><span style="font-variant-ligatures: no-common-ligatures; color: #000000">:</span><span style="font-variant-ligatures: no-common-ligatures; color: #0435ff">1.5</span><span style="font-variant-ligatures: no-common-ligatures; color: #000000"> </span><span style="font-variant-ligatures: no-common-ligatures">animations</span><span style="font-variant-ligatures: no-common-ligatures; color: #000000">:^{</span></p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 18px; line-height: normal; font-family: Menlo; color: rgb(95, 49, 193);"><span style="font-variant-ligatures: no-common-ligatures; color: #000000"></span></p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 18px; line-height: normal; font-family: Menlo;"><span style="font-variant-ligatures: no-common-ligatures">     //先完成一个操作</span></p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 18px; line-height: normal; font-family: Menlo;"><span style="font-variant-ligatures: no-common-ligatures">}</span><span style="font-variant-ligatures: no-common-ligatures; color: #5f31c1">completion</span><span style="font-variant-ligatures: no-common-ligatures">:^(</span><span style="font-variant-ligatures: no-common-ligatures; color: #c32275">BOOL</span><span style="font-variant-ligatures: no-common-ligatures"> finished) {</span></p><p style="margin-top: 0px; margin-bottom: 0px; font-size: 18px; line-height: normal; font-family: Menlo; color: rgb(95, 49, 193);"><span style="font-variant-ligatures: no-common-ligatures; color: #000000">     //上面的操作完成后来完成这里面的操作</span></p>}];

transform方法
