IOS 動(dòng)畫實(shí)例詳解

iOS動(dòng)畫的實(shí)現(xiàn)方式多種多樣，這里就只記錄一下 beginAnimations:context 。

在你調(diào)用 beginAnimations:context:方法來啟動(dòng)一個(gè)動(dòng)畫后,動(dòng)畫并不會(huì)立即被執(zhí)行,直到你調(diào)用 UIView 類的 commitAnimations 類方法。你對一個(gè)視圖對象執(zhí)行的介于 beginAnimations:context:方法跟 commitAnimations方法之間的操作(例如移動(dòng))會(huì)在 commitAnimations 被執(zhí)行后才會(huì)生效。

實(shí)現(xiàn)效果圖：

代碼很簡單，直接貼了，如下：
