這篇文章主要介紹了iOS如何滑動全屏實現(xiàn)返回功能，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。

遜克網(wǎng)站制作公司哪家好，找創(chuàng)新互聯(lián)建站！從網(wǎng)頁設(shè)計、網(wǎng)站建設(shè)、微信開發(fā)、APP開發(fā)、響應(yīng)式網(wǎng)站建設(shè)等網(wǎng)站項目制作，到程序開發(fā)，運營維護。創(chuàng)新互聯(lián)建站自2013年起到現(xiàn)在10年的時間，我們擁有了豐富的建站經(jīng)驗和運維經(jīng)驗，來保證我們的工作的順利進行。專注于網(wǎng)站建設(shè)就選創(chuàng)新互聯(lián)建站。

具體內(nèi)容如下

系統(tǒng)自帶的滑動返回功能，只能滑動邊緣返回，而我們希望通過滑動全屏實現(xiàn)返回功能。

定義BaseNavigationController來取代UINavigationController

UIBarButtonItem+item
