Flip Transition Animation - 翻轉(zhuǎn)過渡效果

默認(rèn)的模態(tài)視圖翻轉(zhuǎn)效果

Interactive transitioning - 交互式轉(zhuǎn)換

自定義交互協(xié)議

#import <Foundation/Foundation.h>

// 1.該協(xié)議的作用：
// 將手勢與目標(biāo)視圖相關(guān)聯(lián)，手勢開始時，自定義的手勢處理類需要向目標(biāo)視圖發(fā)送執(zhí)行視圖轉(zhuǎn)場的命令。
// 2.為什么要將手勢與目標(biāo)視圖關(guān)聯(lián)呢？
// 因為手勢是添加到 window 上的，這樣就可以響應(yīng)預(yù)期的行為。
// 3.為什么手勢要添加到 window 上而不是視圖上？
// 因為動畫發(fā)生的時候，視圖控制器中的視圖將會被移除，因此手勢就沒有辦法響應(yīng)行為了。
